5.0 5Ghz Wifi Issues

Did a full image wipe/install with the official 5.0. I'm no-longer able to connect to my Netgear r6800v2 router with the same channel 48 setting for 5Ghz that previously worked on android 4.4.4.
Any other folks out there with android 5.0 problems using 5Ghz channel?
EDIT: I should add - I'm fully aware the N10 has limited 5Ghz frequencies it works on (e.g. 40, 44, 48) - I've tried 36, 40, 44, and 48... none of these seem to work in android 5.0 with the same router settings. It can see the broadcast and attempts to connect, but IP address is never acquired (DHCP)

I'm having the same issue and my 2.4 network is very slow. Anyone else have this issue or any idea how to fix it.

Yeah I've had issues with 5ghz on every lollipop device I have. Haven't figured out how to fix it yet

I had the same issue and changing to Channel 44 (with Auto bandwidth = 40 mhz) solved it for me, it was on 36 initially

No problems here, did a clean flash of Lollipop and 5GHz is working fine with my RT-AC68U, channel 36, auto bandwidth.

Same problem here. Changed to channel 44 and is at least working

Wiped. Clean flash. No problems. On channel 157. Wish it would tell me if im 300mbit or not. Ac n66u.

Installed from a sideloaded OTA.
Have issues connecting to my Virgin Superhub 2 both on 2.4Ghz and 5Ghz.. Channel 8 and 36 i believe.

Go into Settings -> Wifi then tap the connected wifi network. It will tell you your link speed there. Mine is connected at 300mb/s, while in powersaver mode it drops to 24mb/s.

Mine only connects at 24Mbps and its not in powersave mode

I've similar issue, but both on 5ghz and 2.4ghz.
The connection isn't stable and I get disconnected all the time after upgrading to lollipop. If I'm tethering with my phone right next to the tablet (on 5ghz) it works perfectly. I'm not sure if they've tweaked the disconnect/reconnect threshold base on signal strength.

I'm having problems with 2.4 Ghz wifi too. In Jelly Bean I have a pretty good coverage with my home router but with Lollipop I get lots of disconnections and slow speed. I'm not sure if it's a drivers problem or an operative system change, but I know for sure that it's a pain in the ass.

I'm having the same problem with 2.4 Ghz.

Both 5 and 2.4 are much worse for me as well compared to kk.

I've solved my Wi-Fi speed problems changing one setting in my router: just disable WMM ( Wifi MultiMedia).
Try to enable/disable that setting (can be shown also as WME instead of WMM).
Good luck!

wifi is terrible after 5 update, on both 2g and 5g, constantley disconnects and not loading pages :crying:

My 2.4g is working perfectly, but it cannot see my neighbours 5g network. My Note 2 sees it fine. I checked with Wifi analyzer app.

I can connect to my BT home hub 5 but it only works for a free minutes and then it kind of freezes.
I'm still connected according to my tablet with good signal strength but there is no internet activity making the tablet pretty much a big paper weight for me at the moment.
If some one can help me fix this issue id be very grateful

Connecting just fine at 5GHz 300Mbps with 5.0. I have tested 2.4GHz as well and both function just fine.

I do connect easly, but connection quality is poor... There is definitely something wrong with Wi-Fi on lollipop

Nexus Player Wifi

Hello, I own 2 nexus players, suddenly 2 days ago after working well, both started to develop slow wifi connections, streaming is nearly impossible, I downloaded a web browser for the device and opened a speed test page, the maximum speed registered is no more than 1.5 mbps while my internet connection is 10 mbps, all my other wireless devices get at least 9.8 mbps when tested the connection, strangely in the nexus playerthe speed increases a little more during the morning at the most to 3 mbps. I tried everything regarding the router, at first I used my dsl router wifi then I turned it of and started using my airport extreme, no changes in my nexus players, and getting full speed in my other devices, then I connected the nexus players to the airportextreme 5ghz wifi network, no change, I also tried to get the router closer to the nexus player, no change.
The last thing I tried is to share my mobile 4g connection to the nexus player which is about 25 mbps, I was standing next to the nexus player and the fastest speed it got was 1.5 mbps.
The problem occur in both nexus players, my other wireless devices get full wifi network speed, I dont know what else to do. Is this a common known issue?

How far away are they from the router? I have my router and NP #1 in the same room, and 5ghz signal is excellent. But the signal for NP #2 in the bedroom is lousy, so it uses the 2.4ghz band.
Maybe try using a wifi analyzer app to see what the best channels are for your router?

The router is at the most 15 feet from the nexus player. The strange thing is that both worked fine for about 3 months and suddenly at the same time they presented this problem. Could it maybe a firmware update? Mmmm When I shared my 4g connection I was three feet from the nexus player, I have no further ideas of what could be the problem. Neither google nor asus have responded my emails.

same problem
Exactly the same problem I have. It started today. I have even performed factory reset but without any help. It runs 6.0 software but until today everything works fine. My internet connection is 40/20 mb/s and all other devices works just fine.Anyone knows what can be?

most likely a driver incompatibility issue that came with the latest update.
I assume this to be the case since I used to have wifi problems with the Nexus player in the past, which used to disconnect from my wifi sometimes, especially with my 5GHz wifi, to which it never managed to stay connected more than a few days in a row. And all of those problems are gone after the new update. So I assume that the changes fixed things for some people (like me) and broke things for others (like you). My speed from the Nexus Player is blazing fast as well, it maxes out my connection when performing a speed test.

Thanks for reply.
If it is happend right after I have updated to 6.0 I will understand but three weeks later....
Somewhere I read that NP can be connected with wlan cabel using wlan adapter.If is it possible do you think it will solve the problem?

It should solve the problem. Also I've heard wlan cables come cheap these days on ebay.

Maybe a neighbor is now using a bad channel. See adjacent channel interference and co-channel interference.

Apparently my dsl modem blacklisted both nexus players, i don't know why, so the bandwidth for the two devices was limited. What i did was to reset the modem, problem solved temporarily, I already had to reseted it twice, as it blacklisted the np again. After doing that the speed in my nexus players is back to nearly 10 mbps again.

Tanks! I deleted Nexus Player from wifi devices list (in router network manager) and bandwith comes back!

all 5GHz wifi will disappear sometime

Hi there,
i found that all 5GHz wifi will disappear sometime and only 2.4GHz wifi were left even the signal is very good.
Not only mine but also my neighbor's 5GHz wifi was gone too so i can confirm that there is no problem with my router.
but it can be solved by restarting WIFI in setting menu.
is that a hardware bug or software bug? have anyone facing this problem too? :crying:
ps: using stock rom 4.5.5 & stock kernel

I've too, but disappear and restore itself.

I have the exact same issue, I have 2 separate routers, one upstairs and one downstairs. The one upstairs is a 2.4ghz router and the one downstairs a dual-band router with separate SSID's for the bands, sometimes when I come downstairs I can only see the 2.4ghz SSID not the 5ghz one.

but the 5ghz one shown when u restart wifi, right?

Have you guys already contacted OnePlus about this? I have a few days ago, and I'm currently still in touch with them to find out why this happens.
I for example have the problem, that sometimes the data throughput using 5 GHz networks is absolutely zero, no data is transferred at all (tested with iperf3) and then sometimes it resumes but other times I have to disable WiFi entirely (disable background scan to do that) and reconnect and only then it would start communicating again.
BTW: I'll include a link to this thread on my ticket with them, so that they can see I'm not alone with WiFi issues on the 5 GHz band.

Wi-Fi AC only 72 Mbps

I'm connected to the 5 GHz band on my WiFi AC 2X2 MU-MIMO Router but the link speed is only 72 Mbps instead of the 433 Mbps that I should get on WiFi AC 1X1 Client. The problem is not on the router because my laptop with 2X2 network card can connect at 866.7 Mbps link speed.
When I set my router 5 GHz Mode to 802.11ac only my Mi A1 won't connect to the network anymore unless I set it a again to mixed.
ROM: Stock March update with locked bootloader
Router: TP-LINK Archer C60 V2
5 GHz Mode: 802.11a/n/ac mixed
Channel: Auto - 153(155)
Channel width: Auto - 80 MHz

I'll do a factory reset but now i'm going to select Spanish (United States) instead of Spanish (Ecuador) to see if that works without rooting my device and installing Xposed.

I noticed that my mi A1 has problems connetting to 5GHz networks on certain channels (usually >100). Try switching in your router settings your 5GHz WiFi channel to something like 36 or 40 and see if it helps.

I can connect 5GHz wifi with 200 Mbps link speed by install Magisk modules "WiFi Bonding (Qualcomm)"

I can connect to the 5 GHz network but i can't get expected 433 Mbps link speed with a AC Router instead of that it only gets 72 Mbps (WiFi N).

Maybe try a custom ROMto see if it is a hardware issue or a ROM issue? I have no issues with 433mbps on 5GHz AC.
If you can also try another 5GHz network to ensure that it isn't a compatibility issue with your router, then we can narrow down the possible issues.
Did it ever connect at a higher rate than 72mbps? Or have you only had this phone for a short time? Maybe see if you can find an older stock ROM to fastboot flash to ensure it isn't the ROM that is messed up?

In which channel if your 5 GHz network working?
PD: This is my second Mi A1 because the previous one got stolen from my house so when I bought it the first thing that I did was installing Oreo and then a factory reset. Also I bought the new router the next day so I've never tested it with Nougat.

btw have 72mbit/s on 2,4GHz as well :/ tried on stock and LOS 15.1

In 2.4 GHz it's completely normal unless you set your router channel bandwidth to 40 MHz (not recommended if you live in a very populated area with a lot of nearly WiFi networks) and enable channel bonding on your devices and you'll get 150 Mbps.

I unlocked the bootloader and flashed latest fastboot ROM with MiFlash using clean all and lock, I'm still getting 72 mbps but the WiFi signal has improved and also now I have Mi Drop, Mi Community and Mi File Manager preinstalled. I'll try a custom ROM in this days and I'll post the results.

It's on auto, currently channel 36. I have no problem with 433Mbps connection on 5GHz, being about 20 feet away in another room with 2 walls in between. I can be upstairs in a bedroom, not directly above the router, and still have over 300Mbps connection.
This is running a Linksys EA6900 router with XWRT Vortex/Merlin custom firmware, and Mi A1 running Pixel Experience with Franco Kernel R2.

10mbps wifi download max?

I can only download at 10mbps max on a 100mbps connection. My old phone downloads at like 40mbps. My labtop at 100mbps. So I don't think its my router. Maybe something is wrong with my device. Maybe this is any energy saving feature. Is this normal? Is there a fix or patch?
I have a mi9t. Currently on the the pixal experience rom, but I had this same issue on stock.

Since you had this issue on multiple ROMs so you're network is to blame. I never have slow downloads like this on mine

No problem here either. I get 180mbps over wifi here.

Yes that is the problem, kinda. Both my Mi Box S and my Mi phone only get 10mbps. However I have labtop with a intel card connected to 5ghz that pulls in the full 100mpbs. All are equidistant to the router. I tried changing channel that didn't seem to work.
Is my netgear router a racist?
