WiFi Issues

Hi Everyone
I looked and I could not find info on this issue. I have just used WiFi at home in the past with the Note 3 and it was fine. Here is some history of the changes:
- Old home WiFi was single band wireless N (53mbps) with a second repeater hot spot. This worked well with the Note 3.
- Had issues with the router so I upgraded to a dual band ac router and removed the second hot spot. So now it is just the new router for the whole house.
- Issues now - receive 2 bars at the far end of the house and basic WiFi is OK. Watching You Tube is an issue and it loads, plays for a few seconds, loads more etc.
I don't see a way to tell if I am on ac or wireless N. I was going to try to switch to wireless N and see if that helped but I can't see a way to do this? This router is way faster than my old one so I thought speed would not be an issue. no one else is using the wireless in the house. I would think that 2 bars would be strong enough? I think that wireless N would have a better range so that is why I wanted to try that. I am assuming that I am connecting to ac. Any thoughts?
thx in advance

AC routers have two separate ssid's. One for b,g,n. And another for 5G band. The 5G band default ssid is the same as the other with "5G" at the end. 5G band doesn't have good range, but it has faster speed between connected devices. 5G won't have faster internet unless you have a 100mb download speed. Which is unlikely. So your YouTube issue is either your modem, or a Qos setting in the router. If your router is at default settings it's definitely your modem.
You might be able to get more support on this subject thru a forum for your router, or modem.

why not use your old router from your old home as a repeater? wouldn't that work?

That's called buffering and it's due to low thruput (which is different than speed). It can be caused by low signal strength (due to distance or to the signal haveing to go through too much along the path), noise between the router and the phone, interference with someone else's wifi signal ...
You need at least a couple of apps like Signal Check Lite and Wifi Analytics to see what's going on. Guessing isn't going to give you a solution.

Can't see 5GHz WiFis

5GHz Wifi N signals are "missing" on my XSP.
While at home, my old LG 4X picked up automatically three 5GHz frequencies from local hotspots using WiFi Analyzer app. The Xperia SP doesn't display any, like the 5GHz is not there at all. Tried with all the 5GHz channels turned on in the app, as well as just a few, more common of them, to no avail. Furthermore, WiFi Analyzer is missing the 5G icon on its graph screen.
I thought it was the weak signal problem on the SP so many spoke about, but I found the WiFi performs much better at the same places and circumstances than the mentioned 4X, although at 2.4GHz. I also went to a place where I previously used a 5GHz wifi, but still nothing.
The phone is on .1.254 generic UK FW.

Can anyone help me with this?

No 5Ghz
I can confirm this. I'm on 1.205 and I can't see any 5Ghz AP. The phone is advertised as dual band, even tho I don't use a dual band router this still annoys me, My old and cheap Blu Dash 4.5 gets better speed from the router (130+) compared to the SP (74). I'm happy with the XP but these WiFi issues are really annoying.
For a fix, my uninformed opinion is, this should be addressed on the kernel or driver level, the chipset has the dual band hardware but something is missing between the hardware and our stock FWs.

Wifi blows on 10.5

I gotta tell ya, id absolutely love this thing if it wasnt for wifi issues. This thing drops connection all the time and lags so bad its awful. Done everything I read to do, freezing or deleting apks. Think it would be a home run if it wasnt for the wifi.

I've had mine a few weeks and I've never seen it drop wifi.
Sent from my SM-T800 using XDA Free mobile app

Never had a problem with the wifi, but the lag is horrible

Did you messes with your kernel?

I've got an 8.4 but I'm assuming the WiFi hardware is the same??? I've had mine for several months and never dropped a connection (except when my router went down) . I use it mainly on a 2.4 Ghz network at work. In my office I'm on the other side of an elevator shaft from the access point so reception isn't good on any device in my particular location - but it works and even there never dropped a connection. At home I've got it on 5 Ghz and where I typically use it the signal is very strong. On speedtest.net it matches the speed of my desktop PC which is wired into the router....so it's getting all my internet connection has to offer (service level is 30 Mbps but speedtest.net usually shows 32 - 35).
I'm assuming you have already checked the obvious things like signal strength? Does it drop the connection in some locations but not others? Does it make a difference what router or access point you are connecting to? Interference from other WiFi networks or (if using 2.4 Ghz) other devices like cordless phones?
Try installing WiFi Analyzer (free in the play store). It will give you a real time chart of your signals strength for all access points it can detect on both 2.4 Ghz and 5 Ghz. For example in my Culdesac I can see at least 6 other access points with pretty strong signals (all my immediate neighbors). At my office, on the side of the building facing an appartment building on the opposite side of the street, I can see at least 25 2.4 Ghz access points. Amazing how many are named Xfinity WiFi or Linksys . On the other hand, on the 5 Ghz band in my home I only see one access point other than mine.
Try manually setting your router/Access point to a channel no one else is using. Switch to 5 Ghz if your router has it or buy a new router if it doesn't. This band is a lot less crowded, at least where I live. If your signal strength is low in the place you want to use the tablet, try moving closer to the router to see if that helps. If it does, consider moving the router or getting a second router or repeater.

I use to have problems in my home with 2 things.
A baby room monitor - REALLY tore up my wifi all over the house!
A set of wireless rear surround speakers was a problem for about a day. Lucky for me they have the ability to change the channel they use. Wipped out my freq counter, found out where they were and moved them to ch 11. Unit isn't marked as to what 3 channels you can select from. So the freq counter helped me find where they were and where I could put them. After I got them on ch11 I moved the router to ch4 as there was no one using it near by. Problem solved and have no wifi problems at all with the Sammy.... Matter of fact my router sits on a cabinet 6 feet off the floor. I get coverage over my whole .7 acre Ponderosa while listening to music riding the mower!

my wifi seems to drop once in a while too but i think its the crap router i use.. not sure
i also reset my tab and that helped.

Another thing I just thought of that you may want to check.....
Make sure no devices are fighting with each other trying to get the same address on your network. I just went through this last night. Once resolved, no problem.

A lot of this sort of problem can be fixed by going to 5 Ghz - which may mean a new router if you are using a router that isn't dual band. Most of those other devices in homes (and in your neighbor's homes too) are on 2.4 Ghz so there are a lot of things that compete for that spectrum that aren't even WiFi.

No WiFi issues here

No wifi issues here. I was on stock for about the 1st 30 days on the device and have rooted and installed various ROMs since. I would argue that this device has better wifi than other devices in my house, though my router is not AC so I have no comment on AC performance. I do have an issue with N 5 ghz networks not being seen right now, but that is something I induced.

Too many factors to consider but I can say if other's haven't had issues than it's likely something else.
Distance from access point
Access point's distance from other electronic equip.,
Wireless channel
G or N connection
latest firmware on wireless access point
cabling on AP
trying a different Access Point or wireless network altogether (coffee shop, etc)
wireless sucks to troubleshoot. Constantly changing settings until some magical combination works for all of your equipment.
like to connect my Nexus 5 to wireless N I have to set my 5Ghz channel to be on upper or lower frequency band or something- can't remember which it's supposed to be, though. My PSP needs the 2.4Ghz radio set on a b/g mixed setting. That's the only weird wireless settings I've ever needed to actually get specific devices to connect.
if you're looking for advice we'd need to know the model of your router/access point, though I'd probably go look at a forum where people talk about it.

Hi,
I am wondering, if anyone else having this problem...
My best available 2.4 ghz wifi channel is 13 (2472). If I select this channel my tab does not find the wifi anymore ("out of range"). All my other devices are running on channel 13. All other channels working.
Tried it with stock rom + stock kernel as well as with stock rom + latest UpInTheAir kernel, iron rom + UpInTheAir kernel, iron rom + stock kernel, factory reset, clean flash etc...
Can anyone confirm channel 13 is working on this tab?

Thx, brgds!

Android 7 - 5Ghz WiFi slow

Jun-3 2017 got OTA update a few weeks ago. T813 doesn't have problem connecting to 5Ghz wifi but on 5Ghz the connection is slow. Appears to be capped at about 10MB. Whenever I run speedtest while connected to my 5Ghz network I get 10MB uploads. Disconnect from 5Ghz, rerun speedtest and I get 80MB uploads. Go back to 5Ghz rerun speedtest, back to 10MB. Can reproduce this every time.
I guess I am stuck not using 5Ghz.

change channel to 40 (on router/AP).. and test,.

Found this in a different thread. Changed to channel 40 and speedtest shows upload speeds of 80MB. Netgear recommends using channels above 149 but I will stick to 40. Anyone know why using the lower band 5Ghz channels gives higher speeds than the higher band channels?

do you happen to be using a euro model in north america? what is your CSC and which country are you using the device?

On router (if possible) change channel width to 20 any frequency should fix wifi. Atleast for me this worked
Sent from my SM-T813 using Tapatalk

After changing the routers channel bandwith, this thing goes from 10 mbps to 80mbps. They need to fix this. All my other devices max out at 235mbps on 5ghz. This tab is too advanced to be doing this.

Had the exact same issue on my new T713 and the channel width change from Auto to 20 worked for me on Asus router. Left the Control Channel on Auto. Thanks!

I had this same issue too. I had to turn off Power Save Support then I didn't have anymore 5 GHz slowdowns

Mine had the slowdown with Power Save off - the channel bandwidth was what fixed mine.

hey guys, my download speed is very slow on 5ghz wifi, but few time ago was working well, I dont know what happened. My macbook reach 120MB download and 10MB upload, but my galaxy s8 shows 10MB dowload speed. I tried change my channel width on router, but didn't work.

I'm finding 5GHz to be a real mixed bag across all of my devices - Tab S2 T713, 2 iPad Air 2's, Dell XPS 13 9350 laptop, a Lenovo desktop, 2 Dell desktops, and a Galaxy S7 Edge phone. Performance seems to be inconsistent and I see complete dropouts where the band isn't even visible on some devices. This is irrespective of distance from the router, an Asus RT-AC66U_B1, number of connected devices, etc. When it's good, I see 120MB/sec but other times it will drop off by 50% or more or will disconnect. I've pretty much reverted to 2.4GHz except when I get the urge to test 5GHz out again.

WiFi strength, range, and throughput

Rate this thread to express how you think the Google Pixel 2's Wifi performs. A higher rating indicates that it has excellent range, throughput, and signal strength. Like when you're taking a dump in the bedroom upstairs, do your videos have to buffer or do they come through without interruption?
Then, drop a comment if you have anything to add!

2.4ghz signal strength is improved over my OG Pixel, but the 5ghz reception for me has been significantly worse to the point that I can't use 5ghz in my home with this phone as it has to be much closer to the router than my OG pixel which I can go anywhere in my house with. Anyone else experiencing the same?

Using speedtest.net on 5ghz, downoad speeds on my Pixel 2 are about 20-50% slower than my Nexus 6P.

I've been noticing a lot of drops with 5ghz where my old Nexus 5x has been solid. Lately, it's been from the next room over from my router. I've switched over to 2.4 and will test that out over the next few days.

If it's on a 5GHZ network it will always lose connection if you aren't close to your WiFi router. That's how 5GHZ just works.

How profound, you also lose connection to 2.4ghz wifi if you aren't close enough, that's just how it works!
However what is being said here is that the 5ghz reception on the Pixel 2 is not great. At a range where my OG Pixel and laptop are both showing around -68dbm signal strength the Pixel 2 is showing -80dbm and can't hold a stable connection to 5ghz. I doubt there is anything wrong with it and most likely this just boils down to the design of the antennas and case. The 2.4ghz wifi strength seems to be slightly better than my OG Pixel.

Where are you getting this information from? Are you doing internet speed tests?

On the phones I am using WiFiAnalyzer app from VREM Software to get signal strength information. There are lots of others available in the play store. I have a wifi analyzer application on my desktop as well to read out the dBm values for networks from my laptop.

I concur - 5GHz WiFi lacks range. 2.4GHz WiFi appears fine, though.

5 GHz Band has a smaller coverage area than 2.4 GHz. It has nothing to do with the phone..5 GHz band is the better one to be on. It has more non-overlapping channels which means less traffic assuming you don't pick a busy one. 2.4 GHz band only has 3 channels that don't overlap.

Like with the 5X and the 6P.
Pixel 2 starts with 5Ghz when I reboot the phone and minutes later change to 2.4Ghz and never come back to 5Ghz until the next phone reboot.
This is happening even near the router and in a small house that have 90% 5Ghz signal even in the most remote areas.
The 5Ghz traffic is also pretty low in the area compared to 2.4Ghz which is more crowded.
The router used is an Asus OnHub and both SSIDs have the same name.

some problems with wifi, on 3 different routers, no miracast

Hi

We have a pair of Ubiquiti UniFi AP-AC-Pro WAPs at opposite ends of the house to provide decent coverage throughout (long skinny house with solid internal walls). My Pixel 2 always connects at 5GHz using 802.11ac and stays connected at 5GHz using 802.11ac, and the UniFi WAP controller software shows that the phone connects at a TX rate of between about 500Mbps and 900Mbps depending on distance from the WAPs. With the phone about 10m from the nearest WAP, if I run an ftp server on the phone and use an ftp client on a PC to copy a 1Gb VOB file up to the phone and then back down again, I get a throughput of around 55-58Mb/sec (440-465Mbps) in either direction.
I suspect a lot of the problems reported are due to the generally poor quality of consumer-grade WiFi WAPs.

Same here! My pixel 2 wont connect to the 5ghz network unless its near the router. And also WiFi disconnects automatically frequently. Any fix for this???

Haris, that depends on your wifi signal. If it's strong, the phone is defective, and you know the "cure" for that. If you're going through anything large and conductive, or noisy - a refrigerator, a microwave oven that's running, 5 walls, etc. - that's the problem and you have to get some signal to where you are. (I could never use anything on my deck, which had to shoot 2.4MHz through a microwave to get to the router, when the microwave was running. the only "solution"? Wait.) Now, in a larger house, with a more centralized router, no problem anywhere. No problems finding a clean 2.4 MHz channel, so I have 5MHz turned off.)

Does anyone know the maximum wifi speed possible on a Pixel 2 XL?
