What I'm about to relate is independent of which ROM I am running.
I live in a large apartment in an 80-year old building, with walls that are pretty solid and seemingly difficult for electromagnetic waves to penetrate. A Wifi router's range isn't ever as great as what its documentation proclaims, so I have two WiFi units in different rooms.
Whenever I reboot, Android will always try to connect to one particular router, no matter if the other one happens to be physically closer and offering a stronger signal.
So what algorithm is used to pick the connection, if not the stronger signal?

I just switched over to an SX66 from an Axim X30 (624Mhz) and loving the converged life.
I've had very few, minor problems but the one that really bothers me is the signal strength of the wifi connection.
In my house, from my bedroom with the Dell, I was able to get a great signal to surf with. However, with the Siemens I don't get connected at all. :x I almost have to be within 20 ft of the router (Belkin) in order to connect and then I do connect. It's not a question of speed, only distance from the router.
Also I was in a hotel last week when I bought the Blue Angel. I had the Axim with me at the time. The Axim had a great signal and I was able to retrieve emails.... The BA did not get any signal.
I am using a sotfware called Wifi companion and use the proper WEP settings but it only connects within 20 feet.
Is this as good as it gets???
Please advise!!
Thanks in advance,
Larry
To some extent, the limited range of the SX66 is due to its design; however, 20 ft sounds a bit extreme. In my experience, the range is a bit better than that -- I've picked my neighbor's WiFi more than once, so that suggests a range of at least 50 ft.
One thing that might help is updating your ROM firmware. Customized SX66-friendly upgrades can be downloaded from http://home.comcast.net/~sx66-blueangel/.
My XDA2s will only pick up the signal from my linksys router in the main rooms of my house. If I go into the conservatory (about 20 feet away) I get nothing. My laptop will pick it up ouside some 30 meters away.
From what I've read in these forums this is about average. Something to do with the antenna position inside the device.
EDIT: Right now I'm sat in my bedroom 5 feet above my wireless router in the room below. My signal strength is 50%.
EDIT 2: I just switched the setings from 'best battery' to 'best performance' and the signal strength dropped to around 33%. Wierd.
Any one know if it is possible to force a 3G connection, my house is located right between where 2 towers overlap, as I pull up to my house in the car, I have a 3G connection, but a soon as I walk into the house I can see the 1 tower drop off and the other pick up, problem is the stronger tower is only an EDGE connection. I bought an 8db gain antenna, but that just made the EDGE connection stronger.
Shy of moving my house 1 block over, does anyone have any ideas.......?
did you try forcing it to wcdma only ? were you able to keep the signal?
did it, works great, thanks
I happen to live in an area where I seldom get a signal stronger than 60% outside my home. Within my home, I run between 10% and 30% signal. Due to this I tend to get a lot of dropped calls. I have reported this "valley" in my city as being in a weak signal area for AT&T. Most of it began with 3G. I have now resolved that I should purchase a signal amplifier with an omni antenna that can be installed in my attic that would have about a 35-40 foot cable running to the inside unit. As I understand it, that should closely resemble an outside signal.
Anyone have any suggestions on home cell phone amplifiers that will handle multiple calls simultaneously? It obviously is not totally an AT&T issue because I have several friends on differing networks that have the same problem in my house.
Any help would be appreciated.
Hi guys,
We've just setup our chromecast network. Now with 1 or even 2 chromecasts in the network, everything runs smooth. But if we switch to a bigger network with 3 or more chromecasts, the connection is really hard or won't even happen at all. Anyone experienced this as well? The Wifi is new and quite strong (with additional routers on the first floor, so the wifi shouldn't be the problem).
Thanks for the reply
This is a limitation of WIFI. The more devices you have on a wifi, less bandwidth you will have available. WIFI protocol is using air time allocation protocol because it can talk only with one device at the same time. More devices you have active, more times it will switch between them to deliver all the packages requested. If you have wifi booster or extenders, I would recommend you to grab them all, smack them with a hammer, put them in water, take them out, dry them in the microwave oven, burn them with a torch and trow them in the garbage because that is what they are. Extenders ads latency and packet loss and also is reducing your bandwidth in half before you even have a device on. Do it yourself or contact a professional to install UNIFI from UBNT or similar products. Huge fan of their gear. If you have it properly installed and set-up(not just plugged in) you wont have any problems with any devices not just Chromecast.
BTW, strong WIFI doesnt mean anything. Your wifi is as strong as the weakest device. You can have a wifi that transmits 10 miles, if your other device transmits back only 30ft, it will be 30ft max wifi range even if at 300ft it shows full bars. The best thing to do is add a bunch of AP with the transmit power on the lowest. Keep in mind that wifi 2.4 has only 3 true channels that wont overlap: 1. 6 and 11. If you set them all the same channels they will hurt them self with their own noise floor. If you properly set them up with a spectrum analyzer, to be right at the limit, you could make them all same channel and do cool things like zero-handoff. Performance WIFI requires knowledge and proper set-up not just plug and go.
Curious if anyone here has used any yagi (or other style) antennas to pick up a T-Mobile signal in poor signal areas. Was trying to get my dad hooked up with high speed internet... he's very close to getting 35mbps (end of the driveway), but down the road, through the trees, little to no signal. He has a metal tower up (with wave or some crap, 3mpbs) so i was thinking i could mount a yagi antenna up there and point it towards the tower... just not sure exactly what to get, and how to interface with the phone (d851). Thanks for any help.
(i did climb up the tower with an extension cord and one of T-Mobiles "window" unit range extenders... got about 3 bars up there, but need a waterproof, more powerful solution, as the speeds were fairly low even with the increased signal, was just thinking yagi style could do the trick).
