[Q] Really low speeds on wifi

When I try to use my wifi connection at home its really really slow. Sometimes it just loads part of the websites or some other it doesnt load at all and I have to refresh it several times so it loads. I also have an iphone and a laptop which dont have this problem at all. Theyre working perfectly fine with my wifi connection.
This only happens with wifi, on 3g it works fine. I havent been able to try more wifi networks to see if this only happens with mine

Are you rooted? Could certainly be a kernel issue.

To me it shouts out kernel issue. I've had graphical errors on stock where it shows I don't have any signal but everything still pulls up nice and fast. I would reccomend a new rom and or kernel

It also could be a WiFi issue. I was having WiFi issues with my GNex also that I thought was the phone until I started tweaking my Router settings. Some devices are more forgiving to certain routers. In addition some devices Roam to different AP's much better than others.
I have 2 WiFi AP's in my house to span covereage across 2900sqft. I found that my WiFi was just conflicting with each other causing issues with speed and connection so this is what I did.
My Modem is a TWC Wireless Modem - WiFi turned off.
Router 1 Linksys E4200 is Bridged to TWC Modem it is dual band so I have the 5ghz band set MyHomeAP in mixed mode with a 40Mhz Spread, using 36 as the Channel. The 2.4Ghz band is set to MyHomeAP-N in N only mode with a 40mhz Spread and 11 as the channel. I need a seperate SSID here because it was causing conflicts and I needed a 2.4ghz connection upstairs for my Transformer Prime Tab since it does not support 5ghz radios.
Router 2 Netgear WNR300L with DD-WRT loaded is downstairs on the other side of the house. It is a 2.4 ghz router which I have set to MyHomeAP with a 20mhz spread set to channel 1. This allows my devices that are 5ghz compatible to Roam between each AP without conflicts.
So with all that I am now getting 45 mbs WiFi when I am upstairs and connected to the Linksys and 21 mbps downstairs when I am connected to the Netgear downstairs. The Tab is getting a consistent 15mbps on each router which is acceptable for me. This is an improvement from getting 3mbps anywhere in the else regardless of the closeness to the router or the device being used. I'm now able to maximizesmy use of the WideBand service which gets about 52 mbps on a wired connection most of the time.

The GN has lots of issues with different network gear and a lot of it can't be solved by tweaking. Seems like I've heard the most success stories with netgear. I'm using ubee and trendnet and my wifi isn't great. I get between 5 and 20 mbps and its choppy with a lot of disconnects.

You always have to be careful using multiple Wireless routers in the house, because if they are not setup right you will get consistent disconnects and low speeds. Same thing was happening to me until I really digged in and configured my multiple routers correctly. Check my previous post on how I solved my router issues.

Are you getting good signal when your connected to your wifi

Just one router, the time warner ubee docsis 3.0 modem/router. The rest are trendnet APs at 1,6,11. All with same ssid and security. No interference as checked with wifi analyzer. The wifi just sucks. Not much more you can say except try different gear which shouldn't be necessary. All of my laptops etc work great.

I tried my gnex on other wifi network and it worked well. I tried it again on mine with negative results. Idk what could be wrong, all other devices i have, 2 laptops and 1 iphone work well

What's wrong is the GNs wifi doesn't play nice with all network gear as it should. Just curious, what is your router and APs?

Your basic rate is set to 1-2mbs, so don't expect more than that. Change it to 54mbs or whatever the max is and see if it helps.

5GHz WiFi not working, well sorta....

Wondering if anyone else is having issues connecting to a 5ghz network? I wasn't able to get it working, wouldn't even show up in available networks. That was stock out of the box, and after flashing a couple ROMs. I'm using slimbean now and am able to connect, but I have to turn WiFi on/off several times on the n7 before it shows up and connects. My s 3 connects no problem.
And I've tried all the standard troubleshooting on the router. Even changed some settings on the 5GHz band.
So if someone could double check for me that would be great!

5ghz works great for me. Reception is the best I've ever gotten on that band. Currently on stock, but it's worked in CM10 too

The 5 ghz didn't show up for me either. Had to manually enter the SSID and it connected right away.

On the first boot it didn't show my 5GHz WiFi, but after I connected it to my 2.4GHz, it immediately downloaded an update and rebooted itself. When it came back up, it saw my 5GHz.

My Nexus 7 connects to my 5ghz router band all the time. I think it actually prefers it. I'm using it right now.
Sent from my Nexus 7 using xda premium

Well I think I have it working. I gave the n7 a static address and now after a half dozen reboots its auto connecting every time. I tried changing channels on the router. Tried 20/40 MHz channel width. Ticked on/off all the options on n7 WiFi settings. Nothing worked. Then I set static address on my tablet and router and like I said so far so good.
I'll update if there are any other issues because doing a search showed a lot of other devices having this issue. But none of the results recommended setting a static address. Maybe I got lucky. I could use my 2.4GHz network reliably but I want full network speed since I only have the 16 GB model and do a lot of folder syncs to keep my SD storage free.
Edit: scratch that. Worked half dozen times in a row. Rebooted after I wrote this and it didn't connect.

During initial setup i was not able to connect to my 5ghz but i was able to connect to my 2.4ghz. After setup was complete i was able to go in and switch it manually to the 5ghz network. If i power the device off and turn it back on it would not connect to my 5ghz or my 2.4ghz. I then went into wifi advanced settings and switched to 5ghz only and it connected immediately to the network and hasn't lost it since. This was true before and after the update, i am stock, unlocked and rooted. I also do not broadcast my ssid.

If I am connected to 5ghz and go in advanced and select 5ghz only, it disconnects me from WiFi. It will still show my 5ghz network in range with good signal but if I now try to connect..it does nothing. Keep clicking connect and nothing happens. Then go back and put frequency on auto and the 5ghz disappears. I then have to toggle WiFi 4-6 times before it connects again to the 5ghz.
Strange.
Sent from my Nexus 7 using Tapatalk 4

I had the same problem at first too. Here's what solved it for me: set 5ghz frequency to 20mhz instead of auto, change the channel from auto to any number you want, 5ghz will most likely be completely clear in your area so just choose any channel. After doing that it should see the 5ghz network every time and connect automatically.

Same issue here. But i have to restart my device. Is it hardware or software you guys think?

I'm not sure. Seems like software to me because once its connected it stays connected. And the signal range is really good. Better WiFi than any phone I've ever had. Better than my laptop too. My s3 has no problems connecting. Even with all the router settings I've tweaked its never had an issue connecting with the s3.
Are you able to connect?

In another thread someone noticed his WiFi settings were set to Europe. He said he hadn't changed them and that he was fresh on stock (his first time booted). Double check your settings if you're still having issues.
Settings | WiFi | advanced | WiFi region code.
Mine was also set to Europe as well for some reason. If your router is setup to use a channel not available in Europe this would cause the problems described here.

Update..powered on after a few hours and it did not connect to 5ghz. Went in to the advanced settings and switched from 5ghz to 2.4 and back again and connected right away. Will try the region code, to see if it helps.
update to the update: flashed vanir 4.3.081213 and wifi connected to my 5ghz right away and has continued working through two reboots so far. On stock rooted 4.3 i had to toggle wifi frequency to get it to connect after every reboot.

OK guys, I think I have as real solid lead on this bug. I'll update with some info a little later, I want to test this some more. But for now I'll say that I made some changes and I have had zero disconnects or problems connecting while toggling or after reboot. And I mean 100% connection rate after 50 toggles and a dozen reboots.
Till I can get the info up, one question for you guys having the same issue. Do you have multiple routers in your network and/or custom firmware on your router?

So it's not just me. Hmm.

Yes i think its aome software problem because it worked for me first time only for a 10 mins and then it never connected.
I even tried hard reset but not successfull.

So I tried connecting to it again, and I noticed it keeps losing sight of the wifi connection. It will show my 5GHz network out of range, and then try to connect, then show it out of range for a bit again.

I found a solution go to wifi settings and go to menu and advanced and turn off smart network switch and always allow scanning. And then reset ur modem and router and it should work .
It worked for me and now my 5ghz is working fine.

Mine has worked since I got the phone. With the authentication error, are you positive you've entered the correct key? With the weak signal, have you tried a different channel, maybe some interference going on???

Yup I'm sure, it's the same password as the 2.4GHz network. Besides that, it works for my laptop and tablet perfectly fine.

I reset my modem and router again and now it worked. Guess it just took some motivation lol.
On 2.4GHz I got like 15-25mbps on my wifi.
Here's 5GHz:
Wish Verizon's LTE wasn't pathetic compared to the competition, especially given how expensive they are.

in other devices you can select preferred wifi band to connect.

I also miss this feature. I used to have separate SSIDs for each band but some apps don't like sharing across different ssid names even though it is the same network... Don't know if this is still a problem but it hit me the hardest with chromecast.

Mine always craps out when I connect to 5 GHz, stays connected but there's no data.

This on my T-Mobile 811, I can control it at home, but not at work.

Sorry to revive an old thread but I searched to no avail.
Anyone know how/where to set the wifi frequency band on the G4? I want to force it to use 2.4GHz but the option is not there in Advanced Wifi settings. It is there on my Nexus 4 with AOSP but not the G4.
Thanks in advance.

My router keeps crashing and it's my Pixel's fault - but why?

Yesterday I noticed something unusual. Somehow the internet connection on my computer was unstable. It took a while until I figured out why:
Everytime I turn the Wi-Fi on my Pixel on and it connects to my network, the router crashes. Not always instantaneously, but inevitably.
As long as I keep the Wi-Fi turned off, everything is fine.
It does resemble an issue which plagued the Pixel in December last year, also letting routers (especially mesh networks) crash.
So my question is: Did anybody find a fix for that issue back then? Because Google apparently didn't fix this or patched it back.

Interesting. I have been having WIFI issues at home where the wireless freezes but my wired connection is fine. It doesn't happen all the time, but can happen 1-4 times per week. What internet provider/router do you have? I'm on Cox with a router provided by them.
Honestly I have no idea how to troubleshoot my issue.

I actually have a TP-link archer c5400 and have been having wifi crashes as well. thought it was a google home issue but that was apparently fixed. Still getting crashes. starting to think its my pixel too

I have this too. Asus AC66U router with updated firmware. Pixel 2 XL causes everything to drop - wifi, lan - and it won't come back until I turn off wifi on the phone. Today I installed Beta Google Play services which supposedly should fix the problem so will test this afternoon.

Exact same issues here with my new XL 2.
I resolved it by switching off the dual band on my router and just using 2.4.
Been fine since I did that.

Just wanted to report that I had the same problem with my Pixel 2 Xl and my ASUS RT-AC68U router running on its stock up-to-date firmware. My different Chromecast devices and my Google Home would lose connection to the router and appear as "linked devices" that are unavailable (and would require to be turned off and on to reconnect).
What fixed it for me? Using the Asuswrt-Merlin firmware https://asuswrt.lostrealm.ca/
Not a single problem yet since I did it

Pixel 2 crashes Asus router using 802.11ac 5G
I wish Google would fix this!
All the latest patches and firmware on phone and router. Pixel 2 connects via 802.11ac 5G and router goes offline immediately, losing even wired connections.
After many hours of screwing around with this I finally deleted the Pixel 2 802.11ac 5G profile and kept the slower 802.11n 2G profile intact, which does not seem to have any compatibility issues with this router. It does suck to use slower connection, but it's better than the alternative.
Update: The 802.11n 2G connection from Pixel 2 also crashes the router, so I deleted it now too.

Simple fix is to buy an expensive router next time

This issue is your phone checking multicast for google home devices and if any media is playing back. This was reported back a while ago and many companies have pushed FW to update their newer routers. If you have an older router, maybe nows the time to upgrade as you can get a fairly cheap one for 50-100.
Google WiFi works great.

I wouldn't call Asus AC66U a cheap router but it's still happening.
Any way we could manually block those multicast packets on a router software?
