WiFi speeds

Ok I have cable internet which on a wired connection I get right around 45m/second. On my laptop over WiFi I get around 20 I understand I loose some because of WiFi, however when I do a speed test on my phone I only get 5 is there a way to get faster WiFi on my phone?

Try upgrading to the newest radios. Get them here. http://forum.xda-developers.com/showthread.php?t=715485 . While in WiFi settings, hit your menu button. Should be a option for advanced settings. Click the one for best WiFi performance. It may help

Are you using an Wireless N router and a WiFi N enabled kernel?

I have great speed with a N band Kernnal and a N and multi band router with cable internet

[Q] N7100 5GHz WiFi issue

Hi XDA,
My Netgear router has Dual-band support 2.4GHz & 5GHz...
I don't have problem in 2.4GHz, if the N7100 is in standby mode or in restart it will get connect automatically when the system resumed...
In 5GHz mode it is connecting and speed is twice faster than 2.4GHz,But the problem is it is not connecting automatically when the system resumed from (standby or restarts)... i have checked all the WiFi policies in N7100 but no use.. am getting same Issue when i tried with different 5GHz routers....:crying:
am also am using iPhone5 its working fine in 5GHz mode...
Think XDA will solve my issue soon:angel:
Thanks in advance..
Plz share your experiences

Can any one help?
My N7100 is not connecting automatically to 5GHz WiFi router

i have similar issue with a tp-link tl-wdr4300 router, so it must be some phone limitation. i would also like a solution to that if it's possible.

yes AFAIK the phone doesn't support the 5GHz wifi so its hardware limitation as they said,
hope I answered your question,
Bests

I have the same problem and 3 firmwares have gone by and still the problem exists. Connecting to the 5ghz manually works but turning from off to on, the n7100 does not auto connect to the saved 5ghz wifi. I am using an Apple Airport Extreme at 5ghz-only mode.

Published spec includes 5GHz:
WiFi 802.11 a/b/g/n (2.4 & 5 GHz), Wi-Fi HT40
I have netgear dual band too, but I cant test this because I set all the radios in my netgear plus my powerline extender to the same SSID so the phone can roam between them transparently.
5Ghz has a too short range for me unless I sit in the same room.

Is this related to the "wifi bug" that so many users report, in several threads?
You know, when wifi speed decreases to ridiculous levels, as soon as phone
goes into "sleep mode" (AKA as soon as the screen goes black). In that case
welcome to the club. I've been waiting for a fix since end of January, when we
all were "blessed" with the 4.1.2 fw. I don't think Sammy gives a s**t anymore.
With a revenue of about $8.3 million, I guess they don't care to give a f**k....
If the wifi problems aren't solved with the 4.2.2, this is my last Sammy.

The Note 2 definitely supports 5ghz 11n, but range is quite limited, due to the nature of 5ghz. I've found it only picks up channels < 48, regardless of which region it's set to. Setting a static IP speeds up resume from sleep at times.

I was facing same problem as u mention,repeatedly i gave for repair to authorised service centre & finally they replaced a board,now wifi is works like charm.

Thanx alot! That was news to all of us, I think!
It's strange though, that the problem on my phone
only appeared AFTER the 4.1.2 fw was installed.
Perhaps I should just pass it over to the service
guys, instead of waiting another month(s)....
Anyway, mucho obligado for the info!

Of course it was not easy,I was keep flashing different country stock rom in hop may now they fix the issue,when given first & second time to service centre,they kept my mobile for 3 to 4 days & return me saying no problem found,I am regular reader of XDA so aware of SDS also, I was feeling like cheated by samsung,carrying sick mobile all the time since I have Insane cheap also,but finally they replaced motherboard with sane cheap & one more board for Wifi issue.

Is this issue not the same like the roaming bug? My N 7105 has got both.

I solved it on n7105 with the latest firmware. It now roams smoothly on wifi and it prefers 5 ghz close to the router, at -40 db.

No internet access after switching between Asus RT-AC66U and data

I have no internet access on one certain wifi router (asus rt-ac66u), with my n7 lte, although I can access the internet on other routers and through the dataa connection, I can access my router management though. I did a factory reset of the router and that solved the problem temporarily but the problem came back. Just switching router/tablet on/off doesn't solve the problem
edit: well after turning on/off the n7 wifi worked but now data doesn't work when I disable wifi

If flashing the latest firmware doesn't help. You can try and change the wireless mode of your router. Log into mgmt. Navigate to your wireless settings, change "wireless mode" from "auto" to "N Only."
It's worth a try. What that will do is force N band only, whereas on auto when a g/b band connects the router switches to b/g mode, and that might mess with the Nexus. If the problem you encountered was fine with a factory reset temporarily, all it would take would be a "g or b" band device to log on to kill your n band and dumb down to g/b band.
It's not a bad idea if you don't have any b/g devices to turn off 'auto' anyways. The jury is still out on whether or not it actually benefits an all "N" environment, but it sure as hell won't be switching to G or B on you.
Those routers had issues with their early versions of firmware. They might have straightened it out by now. Upgrade it!

Try changing the WIFI channel used in your router. My nexus 10 had issues on certain channels especially on 5GHZ.
You may also have a Wifi region setting somewhere on your nexus. I remember seeing it before but can't find it right now. The region basically locks your nexus to (possibly) the wrong channels. IE. Not all euro channels work with american wifi channels

I tried different channels and connecting to 2.4 GHz only.

Help!

HELP!!

Let's divide the problem into smaller pieces - is this an N7 LTE problem or ASUS router problem?
Get another router (I use the Asus RT-N66U) and test if it works with the N7 LTE. If it does, then it's your' router.
If it does NOT work wit hth eN7 LTE, then it's your N7 LTE probably have a bad chip.

I installed the kitkat factory images and the problem still persists :crying:

Galaxy Watch messing up my 2.4Ghz wifi network

Hello,
Ever since I've bought my Galaxy Watch non LTE 46mm, I've been having issues at home with the 2.4Ghz wifi network on all devices. Speeds won't go more than 18-20mbps, while on the 5Ghz I reach 350-400mbps.
My router is having these 2.4Ghz settings:
Channel 6, channel width 20mhz, mode 802.11b/g/n
All my devices: tablets, phones show the same behavior: very weak wifi speed on this freq.
Even my watch drops the BT connection to my phone in a matter of 3 meters from it, like from the couch to the desk.
I remember before having the watch that on 2.4Ghz I always got between 60-80mbps no matter the device used.

Have you rebooted your router recently? I've found that helps speeds sometimes.

Yep. I guess the only thing I can do is to try and mess with the wifi channels

That's a good idea. Maybe get an app to see channel usage around you to see what's open. A neighbor may have added things. Maybe change the PW on your router in case someone is piggybacking off it?

Well, my wifi is mac filter based, so no chance of someone from outside getting on. I have tried now with the watch turned off, speedtest returned 50mbps on my phone and 68 on my ipad. Once I turned the watch on and it connected to my phone, both devices fell to 17-19mbps.

Hi, may it be too bad reception with the clock because it is too far from your router? Is it the same problem if you put the clock near your router?

It's not about the wifi connection of my watch.It's about the fact that when the watch is connected to my phone via bluetooth, all my other devices including the phone, are having bad wifi speeds on 2.4ghz. When I turn the watch off, everything gets back to normal.

It sure sounds like an IP conflict on the network.

Question 5ghz WiFi Issue

I bought a Poco F4 (global version, xiaomi.eu 14.0.5.0) about one month ago, I haven't had any issues with it whatsoever, save for the fact that it suddenly won't detect my 5ghz WiFi networks (my main router + a repeater) - and I'm not even sure if this is an issue with the phone itself.
I'm coming from a Samsung Galaxy S20 FE, which was known to have this issue, but to have this happen on 2 different phones is really weird. If I recall correctly this issue started to affect me after I changed my ISP.
The only ways I have to detect the networks again is to go the debug mode and use the WiFi Sniffer Test Tool or reboot the phone, which was more or less the same thing I had to do on the S20 FE (I had to go turn on airplane mode try updating the firmware via debug mode).
What I've tried so far to solve this issue:
1. Changing the channel of the 5ghz WiFi
2. Changing the bandwith from 20/40/80 to 20/40
3. Setting "Use Device Mac" on the phone's network settings.
4. Turning off WiFi Scan Throttle
5. Changing the bandwith to 20
All of the above methods, save for the last one, did not work. And while it does work, it limits the speed of my internet to bellow 100mbps.
The issue is not related to the WiFi coverage as well since it only happened when I'm on my own room, which is where my router is located.
I don't know if I can detect other networks apart from my own since even when they 5ghz detection is working I can't find any of my neighbors' networks. I'm unable to create a 5ghz hotspot on my S20 FE or on my old Redmi Note 9S for some reason.
I'm at a loss on what to do, it happens on both stock and xiaomi.eu, at least and at most once per day.
If anyone else is facing the same issue or has any suggestion on what I should try next please let me know.
Thanks in advance.

I have no problems with 5G Wifi on xiaomi.eu rom
All the time 300Mbit/s
Buy Wifi6 router

This doesn't look like a problem with the phone (s).
Try connecting to another router to see if you have the same problem.

Are they on any specific channel/bandwith?
Both of mine are WiFi 5 though.
Thanks for the reply.

Thank you for your input. I'll try to turn on my old router when the issue happens again. I find it odd that the issue affects both my main router and the one I use as a repeater, but everytime I made any slight change on the main router, the other one's signal almost immediately disappears to apply the changes as well, so it's probably that.

mode: 802.11a/n/ac/ax
channel: 48
bandwith :80MHz
I'm using Tenda TX3 Wifi6 router.
No issues at all. Great internet speed on wifi connection.

The problem is indeed with your router + repeater setup. Your phones are fine.

Thank you! I'm almost certain that the issue is that the bandwith isn't fixed at 80mhz, it's 20/40/80mhz, and when I had the bandwith set to 20mhz I didn't had the issue.

Thank you! It's probably related to the bandwith. I was able to turn on an old router and my phone was able to detect the 5ghz network after the bug happened and my router + repeater signal was missing.

Have you tried resetting your router to the default settings? Or maybe set a specific IP address on your phone in your home network? As said above, it is a setup issue of your network most probably..
