[Q] Does WiFi not work with channel 13? - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

I just got this phone and haven't even had a chance to root it yet, so I'm still on the stock ROM. I'm trying to connect to a wifi network and my TouchPad and MacBook Pro can see it just fine. But my SGS4 can't see it - though it can see quite a few other wireless networks. Our friend's iPhone can see it just fine as well.
I searched quite a bit but only found reports of a custom ROM on the SGS4 not working with channel 13.

Android Revolution HD 2.0.11 - Channel 13 wifi not working

I am using Android Revolution HD 2.0.11 and when I installed it, I lost my wifi connection (my HD found many other wireless networks on my building, but not mine).
Then I manually set my router to channel 11 and it started working again. Previously, I was using the stock ROM and my router was set to channel 13 and it worked just fine.
I guess this may have to do with the higher channels and the wifi driver.
I just wanted to let the developers know about this, but am not allowed to post in the development forum yet. Maybe this is a known fact, but I couldn't find any information on this.
By the way, in case anyone is wondering, I need to manually set my router to one of the highest channels in order to get a stable wireless connection at home.
Also, my wife's Legend with rooted stock ROM has been working the whole time on channels 13 and 11.

[Q] Wifi network problems

Hello everyone,
Recently I upgraded to the 3.1OS and after that I have been having some problems connecting to wifi networks.
I was at my parents house this weekend for fathers day and tried to connect to the network. Every time I connected it would bring the whole network down. On my tablet it would connect, then the signal would go "out of range" and when I looked at my phone I noticed it was back on 3g. After several attempts I determined it was my tablet that brought down the network.
I had been previously been able to connect using the 3.0 OS.
The network provider is Fios.
My tablet is unrooted
Any suggestions or ideas?
Hi, I am experiencing the same problem with 3.0.1 the wifi connection was working just fine. After I upgraded to 3.1 I am loosing signal, the strenght of the signal is much much lower as it used to be.
What I read in 3.1 they downgraded the wifi driver, maybe this is the reason.

Is it possible to check any logs on your router (if it supports it) and see what exactly happened..
It is not about the router, my PC or my Desire get full strength signal. Even with EEE pad before update to 3.1 I had no wifi drops.
So form my point of view the driver is the issue.
There was some mention of people having issues with the non-NA supported channels like 13 and 14. Are you guys using these?
workaround
While not an answer to your specific problem, you could use the wifi on you phone and then tether your Transformer to it...that way you wouldnt be using up the 3G from your phone , still using the wifi technically..
Just an idea to get around your problem...
Was using channel 11, then I found out a lot of other routers are using 11 also.
So i switched to 9. Helped a little bit, but still not optimal.
Let`s see how it evolves. :-D

Slow 802.11n?

I just got my GT p3110 today. Looks like a great device but I get extremeley slow net on my work wifi wich supports 802.11n. I turned on wifi hotspot on my phone and got the speeds expected from a wifi hotspot. I upgraded the device hoping that this was a know bug being fixed but my work wifi is still very, very slow.
Are there any known bugs in .n-networking? I have tried to search the forum but cannot find any other threads discussing this.

Never mind. It seems the tablet has problems using channel 13 on an 802.11n network. Changed the channel to 9 and everything works just fine. Older devices like the iphone 4 and Galaxy SIII have no problems, though. But they are using the g-radio. This makes me think this is an n-radio issue either on the access point or the tablet.
This might be an issue for norway only (so far) since the use of channel 13 was prohibited. So my tab has probably been flipping between the older 802.11g access points with other channels elsewhere in the building and the access point in my department.

SM-N910C 5Ghz WiFi Issue - no Internet connection

My router is Tp-Link Archer C20i working at dual bands 2.4 and 5 GHz. I bought it two days ago and the first day I brought it home, my Note 4 (SM-N910C) connected to it at both bands without any issues, providing me with a stable connection to the Internet. Yesterday, the problems started with the 5GHz band. My phone connects to the 5GHz network successfully, but it all ends there. I cannot access neither the setup page of the router, nor the Internet at all. The 2.4 GHz band works really well in comparison. I hadn't changed any settings, nor installed any apps.
Now my laptop, iMac 2008 and tablet Note 10.1 2014 edition work just awesomely well with the 5GHz band. I've browsed various sites and forums on the Internet and a similar problem seemed to have plagued both Galaxy S4 and Note 8, but the solution was to adjust the date and time. My phone doesn't have any issues with screwed up time and/or date.
I'm running the latest version of Lollipop 5.0.1, stock, no root. I've now tried to both downgrade back to KitKat and upgrade the phone to various firmware versions (and countries') to no avail. I've also upgraded my router's firmware to the latest version - it also didn't work.
Anyone stumbled across anything remotely similar? I appreciate any input.

I had this problem too, but I fixed it by turning off the wifi power saving mode and rebooting.
Did you try turning off the wifi power saving mode in *#0011# --> WiFi(top right) --> Toggle ON/OFF. Then reboot.

Help with WI-FI. Can't connect to 5 GHz at all.

Hello Everyone.
I've got a problem with my WI-FI in my V20 that doesn't allow me to connect to 5GHz at all.
I'm in the UK with a virgin media super hub 2, I also tested it with a TP-Link C2 which is the one upstairs and nothing still. I know it's not my router as I have about 6 other devices which connects to 5GHz perfectly fine, so I know It's a problem with this device.
I have done everything I can think of to try and get it to work as well. I removed all security from the router. I tested it with another router. I used a WI-FI analyzer to see if the device picks anything up but unfortunately it doesn't find anything at all while my PC next to it can pick up 4 to 5. I also changed the channels of the WI-FI and still nothing except that it seen a few high frequencies which I couldn't connect to and the few that I did it doesn't connect to the internet at all. I've also reset the device, and updated the firmware. Still nothing has worked.
This is my 2nd V20 as my first one had the WI-FI problem as well and I hoped I just unlucky with that one and the replacement had exactly the same problem.
I brought it from ebay by the name of eglobalcentral-gb. They quickly got in contact and everything. Perfect communication. The 2nd device was also from this person as well.
The phone is also the H990DS duel sim version.
Thanks Ben
