SM-G960W (Canadian Device TELUS) Wifi issues - Samsung Galaxy S9 Questions & Answers

Greetings,
Recently upgraded from Galaxy S7 Edge to the Galaxy S9 (standard). The phone so far is fantastic in virtually every way. I am still running all stock (fully updated) software and I have not yet unlocked the bootloader or rooted my device. The only issue I seem to be having that may or may not be environmental is what can best be described as wifi drop outs or hanging.
While the phone doesn't appear to disconnect from the wifi network but it will occasionally hang and websites and net based apps will be unable to load content for a few seconds. Often when the hang occurs the Wifi notification Icon will show a solid white upstream arrow and a blank downstream arrow with no blinking activity during the hang. After a few seconds things seem to return to normal. I have had this occur on both my 2.4 and 5.0ghz AC networks. I have tried rebooting the router and resetting network settings on my device. The issue does not occur on any other wireless devices connected to the router (23 total). Router is a Linksys WRT32X running DD-WRT w/ OpenVPN running ExpressVPN for all except 4 clients (Rokus) that do not use the VPN but rather a split tunneled to be direct with using ExpressVPN Smart DNS for media.
Unfortunately I have been unable to test my phone on a different router to see if I can recreate the issue. This is more so to see if anyone else has heard anything about this kind of issue with the s9 or if my case is isolated and thus potentially a defective wifi unit on my SoC.
Thanks in advance for any information or advice offered.
EDIT: I also noticed that occasionally during the wifi hang/interruption the Wifi notification icon will have an exclamation (!) mark. This does not always occur but sometimes and other times it is the aforementioned upstream arrow going solid while with no activity from downstream arrow.

Turn the VPNs off and see if the connection fixes itself, then you can narrow it down somewhat

[Q] WLAN Issues when downloading large files

I have major issues downloading large files via WLAN (e.g. offline cards for travelling or game content from Gameloft). After just a few megabytes the download suddenly stops, the wlan symbol disappears and the download times out.
A few seconds later, the WLAN Symbol reappears and a connection ist possible again. The WLAN issue impacts other devices too, my macbook drops the connection an reestablish it a few seconds later. I tried different settings on my router and even another model. Nothing helps, no B/G/N setting, no adjustments for fragment or rts threshold, removing encryption, changing channels, passwords, static IP.
Does anyone else experience this behaviour too? I'm running now stock kernel 42.0.2.A.0.42 with Baseband 56, as provided from SE. Does anyone have a working solution?
I have the same issue with stock browser. I switched to Opera and now I can download larger files to my phone.
Same here...same FW and baseband...wifi keeps getting intermittent...previously owned xperia play but connection to the same router had not given issues like this...
I assume its not hardware...been looking through the net but no working solutions yet...hoping someone in xda could shed some light...

Intermittent WiFi Dropouts?

I got a Tab S 10.5 a few weeks ago as a replacement for my Nexus 10. Overall, I feel like the Tab S is head and shoulders above the Nexus - but I've had some strange issues. I've had the wifi signal intermittently stop responding - it seems to be more prevalent on my 5GHz network using 802.11ac speeds but I've experienced it at standard 2.4GHz connections as well.
I haven't rooted the tablet yet. I thought at first it might be my wireless network as I hadn't used any other devices that were 'ac' capable even though I have a pair of Netgear R6300V2 routers bridged across my home. However, these wifi signal dropouts persist only on the Tab S - if I turn wifi off, then back on, connectivity is restored. My Galaxy S4, Chromecast, PC, DVR, all stay online just fine.
Has anyone else had this issue? I got my Tab S with the Samsung Book Cover - which I love, but it almost seems like it happens when I hold the Tab a certain way.
Thanks for anyone who can give any feedback.

Did you connect your Tab S with your S4 through SideSync at one point?
Yes, I have used Sidesync. I disabled remote notifications, but occasionally still get a pop-up that remote notifications are enabled even if I haven't used sidesync in days.

I too suffered wifi drop-out and Bluetooth issues. Following this thread (http://forum.xda-developers.com/galaxy-tab-s/general/heads-sidesync-bt-wi-fi-bug-t2828911) I realized that there is a problem with SideSync. Even when not connected it sitll tries to communicate with the tablet and affects the wireless components. I removed Sidesync from my Note II and clear the data from SideSync on the tablet and for the past week I have not ahd any issue with Wifi or Bluetooth.
Thanks. Side Sync Sux.
Brilliant. Thanks. I was having a big problem with 2.4ghz wifi. I though there must have been some interference. 5g was fine. Tried chaining channel and all sorts. Would have thought it was my router but I have two with same prob just on 2.4ghz. It was happening to my phone and tablet, but then noticed only when the table was connected to wifi. Just disabled Side Sync and now the wifi is blazing.

Wifi loosing connectivity (H815)

This has been plaguing me for a while and it's making me hate this phone. I've also seen this issue pop around the internet so it's not just me.
What happens is the wifi stays connected to the router but has no connectivity (i've tried pinging the gateway when it happens, the connection is dead although it is listed in the router as connected). And it happens totally random, sometimes it works entire day, sometimes it happens every hour or worse. This seems to have gotten worse with MM. I used to be able to fix it with turning wifi off/on but now even reboot wont help (it connects to the router but immediately says no internet on wifi), i have to reset wifi on the router for it to start working. I have 2 other androids (kitkat, lolipop), an iphone 5, tablet with a hybrid OS, 2 laptops and a desktop on the wifi working without issues so that kinda rules out the router as the sole culprit (it's a Technicolor crap from my ISP that i can't change, i can only buy an additional AP but i have no idea it will help). Ofc, when the connectivity is lost, the phone is still connected to the wifi, hence doesn't switch to network and i stop receiving notifications, which is driving me insane (also a work phone).
I recently installed an app ("wifi connection manager", the app itself is fairly useless, half the stuff doesn't really work that well, and all the options are really things you can do manually) that has a background service that i thought would keep the connection alive. It worked for about a week and then all of a sudden it stopped. I've tries everything else, short of reflashing the phone.
So after ****ing around for the 1000th time, trying to figure it out i realized that turning the WMM off (router QoS) stops the connectivity issues. Problem with this solution is that my download rate over the wifi drops by half immediately (from 50mbit to 25) and after a while all the wifi connections start to deteriorate to the point where it becomes painfully slow. What's more puzzling however is that when i do turn it off, the G4 connects via 802.11g (and for some reason this makes the connection not lose connectivity). Other devices connect via 802.11n whether WMM is off or on (except the desktop, which has an old wifi card, also on 11g).
Sorry for the wall of text. This and the anticipation of a bootloop is making me seriously regret my purchase.
So my two questions are:
1. Is there a way for me to force the G4 to connect via 802.11g even when WMM is On ? It obviously chooses how to connect on it's own.
2. Given the history of events, is there a network guy somewhere here that could identify wth is going on ?
Thanks a lot for those that made it this far

OnePlus 3 - 3.2.4 Home WiFi issue

Not sure if anyone else has experienced this.
I am using a DLink 880 router and I find that when I connect to my home 5GHz network, loading pages would periodically stutter for 10-15 seconds or longer before loading. Sometimes, loading Google takes a good 30 seconds. I have other smart phones along with computers hooked up to the same network with no issues, and the problem persists even when I turn off all other devices.
Incidentally, I can connect to the guest network from the same router and be perfectly fine. Any ideas what I can look at to fix this?

Question S22 Wifi drops connection on 5g WIFI 6

I am on the June update and ever since I installed a wifi 6 AP from zyxel my S22 drops the wifi connection every few minutes. It either stays omegle connected with about 2mbits or says connected no internet (with the exclamation on wifi symbol)
I tested this behavior on S21, ASUS ROG flow x13 and Intel WIFI Ax200 (PC). All of them are wifi 6 compatible and have no issues connecting.
My 5ghz and 2ghz bands are separate SSIDs, channels are checked and selected to free channels. AP is connected by LAN to router.
This issue doesn't seem to be that uncommon though, it's probably a QS issue or hardware/firmware related...
Should I contact Samsung? Do they offer replacements that are sent before I send mine back? Because I only have one phone atm and I can't reset it without another phone since there's multiple 2FA accounts etc that I would need to transfer first.
Just as an FYI, I work as an IT specialist and I checked everything so far. This issue is not caused by me or my network configuration!
I have this same issue with my new S22 so I don't think it's a problem with your phone. I have TP-Link Omada APs with the same SSID on both bands. All of my other devices work fine, but my S22 couldn't stay connected for more than a couple of minutes. I fixed it by creating a second SSID for 2.4ghz only and connecting my phone to that one. Now it stays connected most of the time. So I guess it's just the 5ghz band that the phone has problems with.
Do you know what chipset your Zyxel AP uses? Looking online, it's likely to be a Qualcomm IPQ8072. My Omadas use IPC8074 chips which are basically identical. Maybe there's some incompatibility between the phone and this chipset? Hopefully it will be fixed in a firmware release for one or the other...
