I tried everything and I found a solution. I also searched the forum and couldn't find a similar post.
When I first received my Note 4 the wifi constantly disconnected. I am talking every 20 seconds or so. I had to manually reconnected every single time.
So my solutions? Either disable mixed signal mode altogether on your router, or set it to use for example B/G only(Instead of B/G/N). Once I set my router to omit wireless N the wireless became stable and for the past several hours hasn't disconnected once.
I hope this helps someone. If this is a double post my apologies.
Good luck!
Almost 24hrs later and not a single disconnect. Just an update.
Going to bump this for new Note 4 owners. The solution is still working.

My Nexus 7 had no problem with wifi connections since I bought in right after they were first released. Last week, I bought a Virgin Broadband Mobile Hotspot to use while doing some traveling. (In some areas, it works a lot better than I expected.) The problem is that fairly frequently, the connection drops and I can't reconnect. When reselecting the device (or any other network) in the list of available wifi networks, I get an error message that reads "failed to connect to network." My only recourse is to reboot. A fast reboot is good enough, but I've done plenty of those and complete reboots.
Then, I can reconnect. That new connection may last ten minutes or many hours. But at some point, the connection will drop and I'll have to reboot to get another one.
I figured this must be related to the Virgin hardware, but when I got home yesterday, I discovered that this happened again with my router. In the 5 months I've had the Nexus 7, I've never had a problem connecting to my home router. So I "forgot" my remembered wifi networks and reestablished them. There are only two, my home router and the Virgin device. Didn't help. Right now, I don't have the Virgin device turned on, so maybe this will temporarily solve the problem. I'm not sure, yet.
One thing that seemed to help was that when driving and using the Google Navigation app, this seemed to be less of an issue. It's even possible that we never dropped a connection while navigation was active. When nav is active, the device doesn't sleep. So there may be some relation there. But plenty of connections were dropped while nav was off and the device was awake. In fact, most drops occur when I'm stationary, i.e., not in a moving car or walking around.
Another piece of info — our other Nexus 7, which also came along on the trip, doesn't seem to have this problem, but it didn't get used that much, so it may be that it would be there, we just didn't have the opportunity to see it happen.
Anyone seen anything like this and/or have any ideas about what to do about it? Why would I need to reboot to renew a connection?
I had a similar issue,it would see connections not connect automaticly and when trying to manually connect it would disappear.I shut off the autoscan for networks off and it works much better.
Hope this helps

Thanks. I'll play with that and see what happens.
The nexus 7 that I purchased for my wife last week is experiencing the similar issue. I can see many network in range but any connect I try to connect will return a message "failed to connect to network".
I found some submitted issues on the Android project thread, but none of them offered any solution.

I'll try this at some other places to make sure the problem persists and will probably return it.
Hi, I'm having trouble with my N7 dropping WiFi signal. Not sure if it's related to android 4.2.2 or what. It was working a while ago, but now not so much. The wifi hangs - like when I'm in chrome a website will take way too long to load, and then a minute later it will load in like half a second. Or when I'm streaming netflix, I'll go for 5 minutes just fine. And then the next 5 minutes it will stutter every 2 seconds.
I'm really not sure what the deal is. Any ideas?
I've tried on a couple networks. I have an asus n66u router. I set up a separate network on the 2.4 ghz band all by itself just to see if it would improve performance. It hasn't. Most recently I tried using my phone a a wifi AP from about 3 inches away. Still the N7 stutters and drops the signal.
Any help would be appreciated thanks!
Sorry if this is in another thread. I tried searching but couldn't find anything similar.
Hi,
I have realized that my wifi connection drops down from more than 20 to only 1 Mbps with my lg g2. It happens with 2 routers and seems that if I reconnect the phone then I go back to more than 20 (and short later in goes down again). Any idea what can be?
No suggestions on this one? I tried the location services changes with no success. I would say it is some app causing issues, but no idea which one could be...

got exactly the same problem
switching wifi off an on solves the problem for 2 minutes or so. then it drops to 1mbps again. tried different routers.
I figured out that it only concerns internet traffic. LAN traffic remains at full speed.
WHO can help please? :cyclops:
hmmm. wonder if this is the same problem a lot nexus 5 owners have including me.. there's quite a big thread on it in n5 QA section
there's no fix but workaround solutions include running in 2g mode or turning off data when on WiFi and even making a script to do so automatically when entering WiFi areas.
http://forum.xda-developers.com/google-nexus-5/help/slow-wifi-n5-t2514501
thank you for that interesting link.
unfortunately the solution turning mobile data off didn't worked for me.
I also tried static IP instead of DHCP - no success.
one strange thing, as already mentioned: LAN traffic to my computer works perfectly with max speed. (copying files e.g.)
so, wifi works in principle. It's about internet traffic only.
but which kind of software/hardware is able to distinguish between internet- and local traffic?
Hey all,
I've had my galaxy s5 since launch and just a couple days ago started to have a weird wifi issue. Whenever my phone wifi is turned on and connected, my home wifi significantly slows down. The moment I turn my phone wifi off, the home wifi speeds up again. This is not a router issue as the same problem occurs at my girlfriend's house and my friends house. Any ideas?
I have the very same issue and after talking to Apple Care because it seemed to be a router issue (Airport Extreme), I was told it was the antenna in the phone that was faulty. This never happened on my S4 or S3. I found an app that I made a shortcut to quickly turn the wifi off, then on, thus speeding things up. (WiFi Connection Fixer *ROOT* by ZEXTR.) I sure wish this issue would resolve itself on its own. Ever find anything?
This does not happen with my S5 and home router. So presumably it's some random conflict with your router settings.
It's impossible to more than speculate on a cause or solution though since you didn't provide any details. The best you can hope for is that someone has already experienced your situation, found a solution and reads this thread.
If you described your router configuration in depth, we'd have a lot more to go on. If possible, an ethereal session or router log at least would go a long way towards elucidating the situation.

Fix? Maybe! (Nope...Issue back)
I THINK I might have found the fix for this weird issue. Go to Settings > WiFi > "Smart network switch" and UNcheck it. My speeds have stayed consistently high for the last two hours, where normally after only 5 minutes, they would drop from 40-50 Mbps down to 10-13 Mbps. Here's hoping!
Sorry...didn't fix it.
Another Fix That is Sticking
I turned data OFF on my SGS5 by using a widget called "Data Enabler" and WiFi speeds have been flying (45-50 Mpbs.) for over 3 hours. (Previously, WiFi speeds dropped to 5-7 Mpbs after 10-15 minutes. Obviously, when I leave home or work where WiFi is not available, I will enable data again. Hope this helps others.
I got my nexus 4 off my brother as he recently got a new phone. I replaced the battery with a new one and all seemed to be going well.
Everything is stock, I have even tried flashing a few older stock builds LMY48M/T to try fix this. I currently have my sim card in an old phone while I am having issues with this nexus 4. I cannot remember if these issues also effected my phone sim network too. I cannot test this until the weekend. I could have damaged the antenna when replacing the battery.. but then when the wifi does eventually connect, it stays connected fine.
I am unsure if it is a problem with my Nexus 4, or my BT HH 4 router.
The issue with the wifi is my home connection says 'Saved' but it never connects instantly. However I could put my phone down and come back some time later and it would have managed to connect. As soon as I turn wifi off, and then on again it will just say 'Saved' and not connect. Once connected wifi works perfectly, excellent signal strength and link speed.
Things I have tried so far:
- 2.4ghz only, 5ghz only, and automatic
- Factory resets multiple times
- Forgetting the wifi network and re-adding password
- Going into recovery and wipe cache partition
- Restarting router
-
As for my BT HH 4, every other device in the house has no issue connecting, (shield k1 tablet, HTC desire S, TF101 tablet, laptops, chromecast all fine) it is just the Nexus 4. Maybe someone could reply who is also with BT and has a Home Hub 4. I cant see how it would be an issue with my router since everything else can connect fine. For this reason I would rather avoid changing settings.
Here are some things showing up when trying to connect my nexus 4 to the wifi from the Home Hub logs.
- Client associated - Client disassociated over and over
- IN: BLOCK [9] Packet invalid in connection (tcp reset attack is suspected:
- BLOCKED 3 more packets (because of Packet invalid in connection)
I have spent so much time searching around trying to fix this and got nowhere, so hopefully someone can help. Any posts I did manage to find were from years ago, I tried the suggestions anyway and still no luck.
