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.

Mine didn't at first either, but after update/reboot no problem. Now connecting at 150meg on 5ghz.

Still hit or miss for me. Sometimes its connected when I reboot. Usually I have to toggle WiFi on/off 2-3 times.

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

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.

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?

Poor Wifi Connectivity on M8?

Hi, is anyone else having poor wifi connectivity on your M8?
My wifi signal will drop completely after a period of time. Conducted speed test and speed turned out to be much lower as compared to my Nexus 5 on the same wifi network, and somehow websites/apps take ages to load via Wifi.
Am on 1.54.707.7 (International) by the way.
Found a video that perfectly describes my problem. :silly:

Yes I'm having the same issue. tried turning off the power saving mode. what kind of works sometimes is if I turn off my mobile data off. I also heard that you Wi-Fi password needs to be 9 characters or else, seems like too much of a hassle. I haven't tried changing the password.

Finally someone who is in the same plight as I am! Haha yes I've tried that too, apparently the signal that the M8 is capable of receiving is weaker than other phones, have a friend who tried on a G2, an M8 and an Oppo Find 7a. The 7a had full bars for WiFi, 1 bar for G2 and the M8 couldn't even connect. :crying:
And about that 9 characters for password myth, yeah have heard about it too! Just counting that out as I don't see any impact it has on the WiFi connectivity though.

possible fix

Hi guys, go to advanced settings in Wifi and uncheck "wifi optimization" give it a try might help

noticed the same thing but i dont lose connectivity the thing is wireless is really good but the signal bars play alot and jumps but if i go a bit far from the router eg in the kitchen where most my phones couldnt get wireless connection i still get it with the m8

Have flashed back to sense to try something so tested once I saw this thread.
Am on 1.54.401.9 and still get the speeds below in my sig with everything set to default and no 'other' kernels installed etc
Ranges from 70mb to 108. (International / UK )

What seems to be working for me so far is I went into my advance Wi-Fi settings and change the frequency from auto to 2.4GHz only instead of auto. I haven't had any issues so far let me know if that helps

I've left mine on auto but connect to 5ghz. (both 2.4 and 5ghz available from router) and again get top speeds.

I don't have any problem at wifi connectivity.

Hi, that worked perfectly for my M8 and my wife's M7. We had big trouble on 2.4 Ghz Networks. After long and disappointing tests for trouble shooting I found this post. And it works. Thanks alot.

am too facing the same problem, wifi keeps dropping consistently.. this happens on each and every sense rom... even on the stock rom.
did a factory reset, but no luck.. also tried turning off and on the wifi optimization in settings-wifi-advanced & changed the wifi frequency band to auto, 5 ghz & 2.4 ghz, but no luck. like it means dropping 12-15 times in 10 minutes. the power saver is also off. wifi in aosp and gpe roms works fine. any suggestions? (firmware is up to date)

Was it due to full metal body? Wifi is worse than my old Butterfly 1

[Q] Poor wifi signal

Sooo I've had my M8 for nearly a month now and I love the thing. However, I notice that I've been having some issues with the M8 not being able to detect or connect to my home and office's wifi. My laptop and my fiance's Nexus 5 can detect our home wifi network with full strength.
Interestingly, the closer I get to my router, the stronger the signal gets, but the moment I move maybe 20 feet away into another room, the wifi cuts out or gets very weak. I understand that distance is a factor, but I feel that my M8 should be able to connect to my router in the next room, especially when other devices can do so with no problem.
I think it's also worth noting that this was not always an issue. This only started happening recently - the only software upgrade that I did was the Verizon push that installed right out the box. I have not made any changes to my wifi network at home or work.
I've tried a couple of things with no resolution, including;
Resetting my router (power cycling)
Restarting my phone
Forgetting both wifi networks and manually re-adding them
Changing my wifi direct name
Turning on airplane mode, turning off my wifi, turning off airplane mode then turning on wifi (this was a suggested method for the M7 that I saw on another forum)
I did some Googling and didnt find much, so maybe I just have a lemon, but I did see that wifi connectivity was an issue with the M7.
Any ideas or suggestions would be greatly appreciated!

I'm having the exact same problem getting over 20Mbps over Ethernet but then 0.25Mbps on my M8 over WiFi even when close to router

Have you guys played around with your routers settings?
What signal is your router on, wireless b,g,n,ac?
Is it throwing mixed frequency? (2.4ghz or 5ghz or both)
Go to WiFi settings in the phone, then advanced, then it will probably say "auto".
Try setting it on only 2.4ghz or only 5ghz see if that helps.

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.

Slow Wifi at home

Noticed a very slow connection when using home WiFi, my wife gets around 70Mbps using her iPhone 7 while I only get 4Mbps with my OnePlus 3! When using my workplace WiFi I get high numbers and my 4G connection is good most of the time.
I have a 100Mbps internet at home and my router is D-Link DSL-6740U maybe I need to change something in the configuration?
Currently running Oxygen OS 4.1.3 but I had this issue even before the latest update.
Help would be highly appreciated!

Cant remember where I read, but try and change in your router the wireless channel the 2.4GHz is running on. By default it may be set to automatic, try setting it to 7 or 11. Iphone and pc's don't have an issue with the auto channel, but some android phones do.

The wifi antenna or chip in the OP3 is awful. I can get maybe 30Mbps on it with a fiber connection. My old Note 4 has hit a Max of 560Mbps sitting right next to the OP3. Both on 5GHz. Note 4 is MIMO, OP3 is a single channel and not very good.

This indead looks like an android-wifi issue , I get the same low speed with my old Nexus 5.. I tried changing the channel to both 7 or 11 but it didn't improve the speed.

The phone occasionally has problems connected to older routers using IPv6. This was addressed in OOS 4.0.3, but they removed the option to disable IPv6 on OOS 4.1.x. If your router has the ability, try disabling IPv6 there. If not, try following this guide and see where it gets you.
