wifi using WPA2

Hi everybody,
A question re., conecting my Desire to the WiFi on my computer. I am using WPA2 for security and the phone will not conect. Is there a fix for this problem, download etc?
the phone excepts WEP but I prefer the stronger protection of WPA2.
Any advice would be gratefully received.

Hi Paul,
To be honest from what i know your better off using WPA as apposed to WPA2 unless you use your WAN for corporate purposes, all your doing is weighing down the packets of data further with more encryption thus slowing your network in general. I've used WPA with mac/linux/windoze for years with no problems!

Paul, you might try changing the password and re-entering it. It's a pain to do it, but it's all I can think of. I'm using WPA2 with a strong password no problem. It's slow entering all the characters but you only have to do it once, assuming you set it up right. Modern computers, routers, and smart phones should have no problem handling WPA2 encryption. The latency out on the Internet is worse than any slowdown from locked-down WiFi. Your router is likely capable of far greater speeds than you are getting from your ISP, anyway.
I'm assuming you are having trouble connecting the Desire to your WiFi router, right? You said "connecting to your computer" in the question, but I think you are trying to connect to the WiFi hotspot in your house/office/whatever. If you are trying to connect directly between the Desire and your computer (tethering, for example) then that's something totally different.
Try and just reset the password on the router to something really simple and try that first. If it works, you probably typed something wrong or something simple like that. Go back once you get it working and choose a much stronger password then. Good luck.

yes i have the wpa2 and i use a very long password without problems...try forgetting it from settings and reentering its info

Thanks guys for your replys, I will try out your sugestions and get back to you.

[Q] how to get WEP to work?!

Hi, I cant get Wif-Ace to work( it just goes to a black screen when i open it) and when it works I dont know how to set it up so i can use wifi! Can you help?!

Try this version from google code. It works fine on my TP2. As far as settings, I basically turned off everything except WEP password. It depends on how your wireless router is set up. Just match wifi-ace settings to what is on your router.

WEP is EXTREMELY insecure. If you have any option, get rid of WEP. If it's not your router, tell whoever owns the router that it is a very insecure protocol and any script kiddie with a laptop can bust into it in less than 2 minutes.
Don't use WEP!!!!

But i need WEP so i can download apps faster!!!

Uh... what? You really think it's that much faster than WPA? Might as well just run an open network. I seriously doubt that WPA/2 adds that much overhead...

di what i do change my modem to wpa2 more fast and more secure before wep easy hack

wep i have ap rogram with the madem of you modem i now you speedtouch password

how do you change it to WPA2

How did you change it to WEP?
The security settings are in your router. Kinda outside of the scope of not just XDAndroid, but xda-devs in general.

I didnt change it to WEP, it just came that way when i bought internet and i dont think i can change it to WPA2 cause i have 2WIRE

Tell your provider then.

i use is wpa2-psk and work with everything waring when you have to this key you have to reconnect everything to the router (put the password again to every equipment). one time i used wpa2 the first some with the modem and docent work very well

MAC Address Changing with every Reset?

Just updated my HD7 to the update with internet sharing. After this, I can confirm that every time I reboot my phone, I get a new mac address. Which prevents me from connecting to my MAC-address-filtered wifi. I've done it 6 times and gotten 6 unique MAC addresses.
Does this happen to anyone else's phone? HD7 specific? or all phones with internet sharing? My internet sharing is turned off.

That's strange, I've never heard of a device with a dynamic MAC address before. Does your phone have one printed under the battery?

Nope, just IMEI, SN and PN. No MAC address.
This must be related in internet sharing somehow.

I can confirm this on my HD7.
MAC changes on every reboot.

I confirm too,i have the issue of mac adress changing every reboot
& my wifi is not visible since the update,My wifi is N and i can only see wifi G near me but not mine

hi
for me too : mac adress change after shutdown.
for time don't shutdown the phone to have same mac adress with my internet box.
htc support tell me that they will answer on monday.
but i think it's a big problem with this update...
Ben

That's a bit strange. Normally you can't change MAC's for yourself, only spoofing is possible. If WP is really changing the MAC adress with every reboot, WP needs a valid MAC adress block licensed from IEEE, otherwise it would be a violation against IEEE.

I thought mac address we're never aloud to change!?

Lol that's illegal as all hell, a dynamic mac address

Gotta be a glitch in the firmware surely? No way that's allowed. Your definitely sure it's not a dynamic IP address you're seeing?

ive also asked this question a couple of days ago right after applying the htc internet sharing update. and ive posted my question here (entry #38) and people provided good answers about it. hope this helps

Yes, mine also changes it's only when i read this thread and test my hd7 and i notice the changes.But I S is a breeze.

The issue is that some people assign static IPs to devices on their home networks, and this is done in most routers via MAC address coupling (MAC a always gets IP z and so forth). That way you can simply block all devices you and people in the residence do not own. I do it on all my machines for development reasons, cause I like knowing I can always use x IP address to get at a certain machine even if I turn it off or it's down for a while for repairs. The IP never changes as long as I continue to use that specific network card in the computer.
I don't know why they would do that. Perhaps for security reasons?

I have the same problem - cannot connect to my University WiFi network as the MAC address keeps on changing....
This is crazy!

They better get on that quick! They could get in a lot of **** for that

putting aside the weird WP7 behaviour for the moment...
MAC filtering is useless as a security measure. It's trivially spoofable by anyone who actually wants to attack your network, and causes a pain in the arse for yourself. do yourself a favour and disable it already. the only thing it might be good for is router-side internet access control of your technically challenged 8 year old who doesn't know how to use google.
just use a strong password i.e. 20+ characters alpha (upper & lower) + numeric + special characters, and proper wireless security (WPA-2 AES, or at least WPA AES) and you'll be just fine.

Confirming
That update was a bag full of $$$$ !Luckly I was able to restore through Zune,but my Bootloader (SPL) was also updated to 5.01 and no way of going back!

With regards to the missing WiFi network - make sure it's not using Channel 13. The new update seems to disable the use of Channel 13 for some reason.
There is also another issue with the changing MAC's - I believe that some "public" WiFi networks such as the cloud use the MAC to remember your device and allow it to connect...

Mac filtering is not useless as a security measure. It's not used by itself. It's used in conjunction with other methods, the same way businesses also hide their wireless network's SSID.
I'm not filtering on an Open Connection. That would be retarded.
Seriously...

im not sure though but im guessing so does other apps with secured log in parameters. i do have the bank of america app. right after i did the update, and after inluding the new mac to my networks allowed list of mac addresses, the boa app again posted a message saying that the device where im accessing boa has not been used previously to access the account. so im guessing that it saves all the mac addresses of devices that accessed a boa account.

Help... Wifi Mac Address Changes On Every Reboot

Hey fellow GN users!
I seem to be having a problem with my wifi mac address changing every time I reboot... I was wondering if this is a hardware or a software problem? I have mac address filtering set on my router so it would be convenient if the mac address didn't change... I'm still on my first week with the phone and I want to make sure everything works before my 14 day period is over. Is anyone else having this problem? Anyone know a fix if they are having the problem? Any help would be most appreciated! Thanks!
Galaxy Nexus (LTE)
Unlocked, Rooted
Flashed with Android Revolution HD 2.1.2

Welcome to the club!
http://code.google.com/p/android/issues/detail?id=23330
From my support call to Samsung, this is apparently a software issue, but I'm not sure I believe that 100%. For me, I switched my home wifi around to use WPA-2 with a ridiculously long password and no MAC filter to make me no longer care, but that's just me I'm secretly hoping to be the guy that can tell Google "hey - you fixed it!!", probably why I don't push harder to exchange my phone.
Please add a comment/star to my Google Code issue if you don't mind; the more people that chime in the better off we will be. I truly believe that a lot of GNs have this problem since it's not something that most people would notice.
If getting rid of your MAC filter is impossible, you should really consider exchanging your device, I imagine it will be quite a while (if ever) for this to get fixed. Call me a pessimist if you must.

Odd, isn't a MAC address suppose to be hard flashed to the radio?

Mine started changing the Mac address today after rooting. The last month with it running stock, no issue. Hmmm, used the Galaxy Nexus tool kit for rooting.

MAC address filtering is not really a good security measure. It is very easy for someone to see the MAC addresses connected to a particular WAP and clone one of them.
You are much more secure using WPA2 with a decently long password.

I just started experiencing the problem yesterday. My phone DID have a 2c:44 address and I switched roms pretty frequently. I flashed an update to the Codename rom that I had been using for a while, and I wasn't able to connect to my router. Knowing what I thought I knew about MAC addresses I didnt think about it, i rebooted all sortsa crap, then thought what the hell check the mac filter list, and sure enough mine had changed, and now i'm sporting one of the dreaded 00:90:4c addresses and the last few characters change every reboot... I am not a happy camper.
I understand how it isn't an amazing security option, but in a small apartment building in the sticks in PA I know my neighbors have no idea how to get around it. WPA2 uses up too much bandwidth overhead for streaming 1080p over wifi. That's why I dont use it and use MAC filtering.

It is not a bandwidth overhead but a resource hog. But I get your jist. I save all my HD streaming for wired.

Have you done an EFS partition backup?
Sent from my Galaxy Nexus using XDA App

I didnt know what and EFS partition was until I just googled it and I've been rooting / rom'ing phones and devices (5 different phones and 2 tablets) for the last 2 years and never once heard of it.. that being said i did a nandroid backup and restoring it did not help
I'm going to try Odin flashing back, I read somewhere it fixes IMEI / EFS corruption, heres hoping it works for wlan mac addresses. Only place I found an Odin image of it was from megaupload so it will take a long time to get it...
Edit: if you clicked on the link for the firmware i posted, do NOT click it, i think that was GSM

Well that was a bust, odining back didn't help... I dont want to risk swapping the phone out considering i put one of those zagg screen protectors on it for a phone that is going to have the same problem... I am concerned because of the fact that i did have a valid sticking mac address, and all of a sudden it just stopped which leads me to believe it is totally software related.

Was just about to say it. +1000. There is nothing about MAC address filtering that is secure. Anyone can spoof the MAC address, and its easy to intercept them when in range.
Use a normal security protocol and you'll be better off all around. MAC filtering is just a hassle anyways.

Thank you for your concerns however as I said before I dont need crazy security, I just had to deal with rednecks connecting to my router using torrents a couple times. Since that has happened and i enabled mac filtering I haven't had any problems (i would know because my internet bandwidth would go to crap)
Actually setting up WPA2 is more of a hassle than logging into a router, clicking on one link and typing in the mac address rather than somehow finding a way to configure my network to handle the bandwidth with WPA2, which I have tried, but even with a dual band n wireless ethernet bridge with gigabit out to a gigabit switch doesnt do the trick, disable wpa2 all of a sudden all my video stuttering woes go away.
That is at a personal level, at work I have MAC filtering not to connect as a security measure but my ip address is assigned based on it, and well it's much more complicated than at home... please if you are going to post something in this thread try to be helpful.

Again, it has nothing to do with bandwidth. It has everything to do with the devices ability to encrypt and decrypt packets at full speeds, which obviously your device cannot do. You might want to step up to something a little more powerful.
I can do 1080p streaming on a G network with WPA2 enabled. The difference between my setup and yours? I am using an enterprise grade WAP (Cisco 1242). It has no problems whatsoever doing the encryption and decryption at the full wireless speed.
And I think you mentioned you were located in Central PA, and all you had to protect from was hicks. Well, I am one of those hicks (Live in Central PA as well) and I LOVE cracking in to WAPs

I am having this issue now. any solutions?

WPA2 isn't crazy security. I wouldn't recommend anybody running anything less than WPA2 with 256 bit AES encryption. If you can't run that I recommend upgrading your hardware.

so... i just started having this issue after my battery died last night now today I have a different MAC..
This has to be fixed at kernel level or maybe a script to set the mac at bootup time can be used. really annoying and stupid

802.1x wifi problem | galaxy gio

Hey,
I want to connect to a 802.1x security wifi network on my school, it does connect.
It sais I am connected but I can't browse the web and all my apps dont refresh either.
Is there anyway I can fix this? Maybe with some setting or change in root?

work fine on mine

I'll install cm9 as soon as I can, and see if it fixes my probs. Otherwise it could be a chipset problem, that it just doesnt support. Some other people on my school also cant connect (budget phones).

I think its weird that some devices can connect and others not, on my school, some galaxy s or galaxy ace will connect while others can't. I have cyanogenmod 7.2 with android 2.3.7! I think it should work but someway it keeps connected, so I am connected to the router, but I can't browse the net. Maybe it cant open default gateway in someway?

maybe that router is not compatible .. i have the same problem in some places..

I think it's weird some devices connect and other do not, maybe it has to due with diffrence in android versions? I use cyanogenmod 7.2, android gingerbread 2.3.7

Oi, there is so much that could be going on here...
Its an Atheros AR6003G chip, which as far as i know, supports 802.11 A/B/G/N, and hardware encryption for WEP/WPA...
Odds are, if its an 802.1x type network, the chip will do the encrypting/decrypting after the handshake is completed, provided its set up correctly. WEP and WPA are set up by using a Pre-shared Key that all users need to have... If you study how to recover the key, you'll find that the hash is created by taking the plaintext passkey, running it through the specified algorithm, then salting it with the name of the network. So long as all devices have the correct network name and the correct plaintext password, any device can connect to the network, because they'll all end up with the same hash.
802.1x encryption is different. It uses an authentication server. This makes it similar to any modern computer you log onto. You provide the computer with your credentials, and it checks it against the server. If they match, then you are allowed access. If they don't you get an error message. Which means, that if anything is broken, it won't work. If you don't use the correct authentication protocol, it won't work. If you don't have the right certificates, it won't work.
Best advice I can give is, double check everything. Make sure your Gio has the correct certificates and that its using the correct protocols. Double check your IP/Subnet Mask/Gateway addresses. If you don't have an IP address, you'll have to manually configure it. If the Subnet Mask is incorrect or the Gateway address is incorrect, it won't work either. Also, check your DNS server addresses. If those aren't correct it won't load any webpages using URLs. It will only load them using the IP address of the server. Which means, telling the browser to go to www.google.com won't work, but if you tell it to go to 173.194.67.99:80, it will load the Google homepage.
Hopefully this will give you somewhere to start...

Yes true, only problem is that static IP's dont work, otherwise I could just copy the DNS and gateway numbers from a device it does work on. It uses DHCP and I think that I have the problem you told about.I dont think our school uses certificates cause a friend of my (Galaxy S) can connect without having installed certificates or something.
I think its an hardware isue and it cant decrypt the code well, my WIFI indicator stays white, with internet acces it should turn blue or green.

That is very very odd... I use a Linksys WRT54G2 router at home, and its set up for DHCP. Its address is the standard 192.168.1.1, and it can address 50 clients between the addresses of 192.168.1.100 and 192.168.1.149. However, if i set my computer up to use static settings, it works just fine... Granted the networks are probably set up differently.... but the theory should work just fine...
Code:
IP: 192.168.1.4
Subnet Mask: 255.255.255.0
Gateway 192.168.1.1
DNS: 64.59.160.13, 64.59.160.15
Are you positive it doesn't work?
If you can get me the encryption type, IP address, Subnet Mask and Gateway address your friends phone uses, I may be able to help more... The more information you can get me, the better.
The only reason I can think of that would cause it to not work is that the IP address is already in use, or the Subnet mask is incorrect... It shouldn't matter what IP address you use, so long as the subnet mask and gateway are correct... In theory anyway...

I'll gather them and put them in a post!
Thanks for your help so far,

Im on the same school as runedegroot but the neteork does work for me, and i dont think a stattic ip will work cause the network is spread over a lot of routers so if any other phone gets that ip via dhcp it wont work anymore

Actually that was for willie1001...
And its possible that changing the reguatory domain could work. If you're running software designed for the states, it would disable any channel above 11... But then again, if you can "see" the wireless network in the settings menu, it would make sense that its programmed to use a channel isn't above channel 11... Which would mean that changing the regulatory domain wouldn't help it at all...
Come to think of it, if your MAC address is blocked, it wouldn't allow you access... But then again, you'd have to do something for the school to block your MAC address. And if the other students can access it, then it would have to be specifically you who did something to piss off a teacher.
Also, any information you can get me about the router would help greatly. By figuring out the manufacturer of the router and the model number of the router, its possible to narrow down the likely IP addresses that the router would use..

Man, thats odd... I assume you aren't on the North American continent... Where did you pick your Gio up from?
You know... Its possible that the issue you have was fixed in a base band (modem) update... You could try flashing the phone to the latest OE firmware (Not necessarily the one that came with your carrier as branded firmware tends to take forever to get updated), and see if that works...
