[Q] HELP! HD2 wifi is completely unreliable

My wifi is spotty, at best. I've tried every ROM but every ROM has the same issues: wifi will work for awhile, then it won't, then I power the phone off, then it doesn't work after I power it back on, then I disable it and re-enable it, and it may/may not work. Basically, it's totally unreliable.
I AM running a 2.4 mouse/keyboard combo, but I've tried different channels on my router: 1,6,11 ... they all have issues. My router is a D-LINK 615 and supports 801.11b-n.
I have an iPhone and it is rock solid on the wifi; plays nicely with the keyboard and mouse and doesn't miss a beat. But I REALLY want my HD2 to work: it's more baddass!
Can anyone help me out?

by not working, could you be more detailed? coz if the problem is about wifi went to sleep state after you lock the phone, then there's a settings for that.

Where's the setting?... I must have missed it! I can restart the phone and get the wifi symbol, but the reception bars aren't fully lit... only the very lowest (I'm on a sense build now).
I go into wifi settings and it says 'connected' ... but I try to load the browser, or marketplace, or Amazon AppStore ... and I'm not connected. I disable wifi then I renable it and my wifi bar is full! And the wifi works for, maybe, 30-45 seconds before it doesn't work again.
Really, really odd. And this is how it behaves on all ROMs I've tried.
*EDIT* I just saw that my wifi sleep policy is set to 'never' go to sleep.
I just turned on "best wi-fi performance" but I have my doubts that it will work... and my battery is going to suffer, big time.

I suffer from similar symptoms.
Wifi will show as being connected (but sometimes the signal meter is obviously off), but things like the browser won't load. It'd be nice if wifi just dropped entirely (and then push notifications would work again), but it doesn't. It just doesn't work; it shows as being connected, but I can't load things.
If I disable/re-enable wifi, it works again.
I think most of the time (for me) the trouble is the result of going between different APs or coming back to an AP, but still sometimes problems occur even when I'm sitting still at a single place (I'm connected to a campus network, but I've had this problem happen on a 1-router network before too).
I've found that, overall, the g.lewarne kernel works really well after a few reboots (wifi sometimes still gets "stuck," but not as often...), at least better than Raf 1.9. But... problems still exist.
Hope you find a solution here! There have been several threads with this already...

Thanks! Help installing a new kernel...

Hrmm.... I've been searching high and low for a good kernel and was thinking it might be the issue. I found g.lewarne's kernel http://forum.xda-developers.com/showthread.php?t=917590 ... but I have no idea how to apply it to my current build: http://forum.xda-developers.com/showthread.php?t=1027768
Is it possible to apply the g.lewarne kernel to CME Desire HD2?

I just flashed g.lewarne's GL_CORE_V5 from here:
http://forum.xda-developers.com/showthread.php?t=917590&highlight=reboot
... I flashed the whole ROM and I'm getting zero wifi. Even with the other kernels I was able to get some wifi, but none with this one. I like the ROM look a lot, but nothing doing on the wifi front.
Anyone else have suggestions??

WPA vs WPA2
Make sure you set ONLY WPA and TKIP in your router settings... I have much more reliable wifi because of this.
Also, choose specific wifi channel ... channel 6 works for me, and I've seen channels 1 and 11 as recommended channels as well.
Mixed WPA/WPA2 and TKIP/AES modes were horrible for wifi
FYI!
My ROMs are working relatively well now... much better than mixed modes (no wifi working)

Ah. Unfortunately I have little control over the wifi infrastructure on campus (I'm in a college environment). That said, I'm not connected to the WPA2 Enterprise ssid but the unencrypted one.
Good to hear you found a resolution!

I have found that WiFi works just as good as my laptop when I'm running Windows Phone 7. Much faster at connecting and can connect further to the edges of signal then Android. I wonder why this is.

Wifi Issues

I'm having problems connecting to the corperate wifi with my Nexus 10, I've used an android tablet berfore on it, TF101 connected without any problems, I've seen issues reported with the Nexus 7 and Wifi, has anyone else had and issues connecting to WPA/EAP with Certifcate authentication.
The device is crrectly registered as it can connect to another SSID which uses the same mac database

Working fine for me, however I have been disconnected twice in the last 2 days,

Bump.
Any fix to this issue? We use WPA/EAS and I get "not in range". Some people got it to work and some didnt. there's an open bug being tracked on Google (Issue 34212) but no workable solution on the N10.

Having problems with optimium wifi. I have to sign in everytime, while on my phone/laptop its not needed.
I downloaded the wifi register app from optimium, but it can't sign in with that. Any solution?

My connection stays strong (max bars) when for example playing a youtube video, but after while the video endlessly buffers (or freezes) until, either I jump in and out of multitasking screen or restart the WiFi connection. It's as if it can't reinitialize the stream for some reason. I have the same problem downloading apps and other media, i.e. good signal, stable connection, but just seems to time out continuously. It's driving me mental, without reliable WiFi the device is next to useless. I'm hoping it's a software issue that will be addressed soon, but if not I suppose it's RMA time.

I had the same issue with YouTube last night. It took me a while to get the connection back at one point. I rebooted the device and the router and I eventually got my connection back. I would tend to think it is a combination of Android and the router that will eventually be worked out with an Android software update.

Selective Wi-fi

Hello everyone,
I checked the forums and I haven't seen anything like this, but I'm hope my situation isn't unique.
So I got the Nexus 4 and I love it. I have it linked to my wi-fi at home and the campus wi-fi. Every time I got to the college campus it links just fine. However, when I get to the home wi-fi, it sometimes takes a while for the phone to connect to the wi-fi, or say that the wi-fi is out of range.... even when standing next to the router.
I've tried rebooting the router, rebooting the phone. When it connects it's awesome. Sometimes I have to turn off the wi-fi on the N4 then back on again for it to connect.
Does anyone know what this may be? Anything would be great help.
P.S. - everything else works on my wi-fi just fine. A couple Rokus, a notebook, and etc.
Thank you

Nexus 4 has several flaky wifi issues. When I first got mine I could not get it to connect to my home router at all. Then it just started and has been working fine ever since. You may try changing your frequency settings on the router or using a different security protocol. In my case it seems once it got connected the situation was resolved. Good luck!

I tried changing the frequency, seeing that my neighbor was on the band as me. I'm not sure if that did the trick, but now my N4 seems to be picking up the signal a little more quickly.
Thank you for your suggestion.

Same issue here. Sometimes I'm connected to campus wifi, I drive all the way home and look at my phone, it's still trying to connect to campus wifi. I have to turn wifi off then back on for it to disconnect and auto connect to my home wifi.

Why does YouTube hate the internet connection at my house?

Hey Everyone,
I've seen posts about problems with YouTube constantly buffering on HQ and have tried every possible solution I've seen, but I'm still having issues. I am hoping someone can help me.
HERE'S WHAT IS INTERESTING... when I use my phone as a hotspot (T-mobile HSPA+) and connect my N7 to it, YouTube works absolutely fine, no buffering at all! What is up with that? The internet at my house is fast (Verizon Fios) and I can stream and play everything fine on my N7 except for YouTube videos. But, once again... YouTube works fine when I connect my N7 to my phone's much slower wifi hotspot! So, obviously YouTube (both the app and web browser have the problem, but the app seems a little worse) has a problem with my home internet connection. Does anyone have any ideas on how to diagnose and fix this? I've tried rebooting the router. The Verizon Fios box is a kind of "all in one" device, so I can't swap out another router. Is there any settings I can try, either on my N7 or somehow on the router itself (don't know much about routers)? Any ideas? The Nexus 7 is such a great device for watching videos, etc... it's really aggravating to not be able to watch YouTube videos on it.
Thanks for any help you can offer.

You're not the only one buddy. It happens to me as well. It's really annoying. When I watch YouTube videos on my PC it's quick and on the n7 you know..

Thanks for the reply. I definitely realize that I'm not the only one. But, why does YouTube work absolutely fine on my N7 when I tether it to my phone (a much slower connection)? This means that YouTube CAN work on the N7. It just doesn't like some routers apparently, or something like that. And why does YouTube work fine for some people and not for others on the N7?

I doubt this is the problem, but your neighbors could be using the same channel as your WiFi. So their WiFi interferes with yours. You can download an app called WiFi analyzer. It will show you the channels you and your neighbors are using. It will also show you better channels than what you are on. You then go to the IP address of your router and change your channel.

Could be. Could even be microwave ovens or portable phones/base stations if the WiFi link is using 802.11b or 802.11g (or even 802.11n, depending), as they also overlap the same ISM bands that B and G use.
Resolving performance problems (as opposed to gross connectivity issues) is tedious work - the root of the problem can be in a very large search space.
With enough packet sniffing (tcpdump or Wireshark) you can sometimes ferret out network performance problems; but it's not for the faint of heart. Your eyes will bleed from looking at raw packet data without purpose-built tools. You have to follow the data where it goes, too - you don't know if the problem is delays as a result of small % of packet loss, or something more twisty than that. If the cause is a small % of packet loss, you would be looking for TCP segment retransmissions by the server, or duplicated ACKs from the client (tablet). The will occur along one link (e.g. WiFi) but much less frequently along a different link.
Sometimes problems can be detected by just looking at gross statistics on each network interface (e.g. /sys/class/net/wlan0/statistics/* on the tablet versus something equivalent on the router) - even easier to do if you can manage to clear the counters without rebooting as you can then run a "youtube test" right after clearing them to see if the drop/error counts are actually happening when you are using the app. Either that or just collect them twice (immediately before and after the youtube test) and use subtraction.
The OP might be able to prove it's not his ISP link if it is possible to use a OTG+USB Ethernet nic plugged in to the N7 (use ethernet to his home router instead of wireless), but I can't say I've tried this myself, and I suppose he probably would prefer not to spend money solving the problem if it can be avoided.
There are some tcpdump-based tools such as "Shark for Root" on the market. Not that using the phone itself for sniffing will be all that easier, but setting up a wireless sniffer is even harder and more expensive, and since the OPs router is an "all-in-one" box, the only way to intercept traffic off of it will be if it's admin tools allow you to dump traffic to a designated ethernet port. Not typical for consumer devices, but who knows.

To the extent that the YouTube app is unaware of which interface it is getting it's data from, that's a demonstration right there that the problem is probably not the N7 or the YouTube app. Could be your ISP or your home network.
Out of curiosity - does your phone do WiFi tether in Infrastructure Mode, or is this a USB tether? (afaik, the N7 doesn't work with ad-hoc WiFi tether... unless you've got some tricks up your sleeve).
hope some of that helped

I've also been having this issue since i got my N7. It happens on every single WiFi network I'm on. Using the web based YouTube doesn't help either. I was getting so aggravating today that i almost threw my tablet across the room.....

Thank you so much for taking the time to write all that. I'm afraid most of it was above my head unfortunately. But, I'm trying to use your words to help me as I research at least
As for your question above, I think I may have used the word "tether" wrong. I just meant, when I use my phone as a wireless hotspot and connect to it on my N7 YouTube videos playback flawlessly, which seriously makes no sense. The wireless network at my house is much, much faster and I use it all the time to stream YouTube or hi-def movies to my TV (Netflix) without a hiccup. And my Nexus 7 streams Netflix as well just fine over my home network. It's just YouTube that is constantly buffering. Which would imply that it's the YouTube app... but, then why does the YouTube app stream fine when connected to my much slower phone connection? It's not making any sense!
I really appreciate you trying to help!
Thanks again,
Mebborne

Did you see this thread?
I wasn't aware of it when I responded to your post. Seems like you are in good company. I didn't read that whole thread, so I can't summarize or tell you if there are any fixes. OTOH, given the number of people saying "me too", I wonder if it is an ISP issue - purposely throttling of connections coming from youtube.

super slow apps via wifi on home network, works great using data or other networks

Hoping the community can help me troubleshoot this issue I'm having... on a new S10+ (SM-G975W) running OneUI 2.0 Android v10. I cannot seem to figure out why apps like DAZN, Sleeper, Pluto, Microsoft News, etc. all run extremely slow (if at all) using my home network wifi. I can literally open an app and it won't even load while I'm on my own wifi, however once I turn my wifi off and use data it loads instantly. Every time. When I'm on away wifi networks (work office, friends places, etc) it works perfectly. Other devices on my home wifi network work perfectly using wifi. Other apps on my phone seem to work without any issue while on wifi (insta, youtube, brave/chrome, google news, etc)... so the wifi certainly does work on this phone; I can do speed tests on fast.com and using the speedtest app and get great results.
I've tried:
- toggling between 2.4ghz and 5ghz networks
- resetting network settings on phone
- resetting network settings on my router (EA 7500 V2)
- forgetting/restarting rejoining wifi network
- hard resetting my router
- toggling various power mode options from high performance to optimized to medium
None of these have worked. I can't seem to figure this out. Does anyone have any ideas for what I can try to do to resolve this - it's driving me mad.

Any help here? Wrong place?

Maybe you could try to change channel of 2.4GHz and 5GHz wifi in your router. If it's possible, try tu put DNS of your IPS in router. Or try to change router for another one for test.

Thanks for the help... I have tried toggling betwwwn 2.4 and 5ghz settings. I will look up what the DNS would be and try that. Router seems fine - worked / works with everything else..it seems the issue is on my phone.
When I put my phone in airplane mode then take it off, the wifi works well for a.period of time. Then, it stops again.

Do you know of any? I cant find any to turn off.
Also, I have now hard reset both my router and my phone, still the same issue. DAZN wont even load on wifi. Works on other devices' wifi on the same network. Works with cellular data instantly.
Could it be my ISP that's blocking certain types of traffic?
The behaviour is so weird, for most apps it takes 20ish seconds before the wifi 'kicks in' and starts working. I have no throttling or other apps installed.

It also doesnt load certain online streams. Some work, but some dont, and if i switch to cellular they work perfectly.
PlutoTV is another app / stream that simply does not work while using wifi, but works using cellular.
So in summary:
- S10+ DAZN and PlutoTV apps definitely do not work over 5ghz wifi connection
- other phones using same apps on same wifi networks work pefectly
- I've hard-resetted my phone and router and it's still not solving the issue
so... what in the heck could this be?

Is the WiFi-Safe Mode enabled in the developer settings? If yes, try to disable it.

FYI - figured it out. By disabling IPv6 on my router it solved my issues. Hope this helps someone else in my situation.

Thankyou, was having weird behaviour on all android devices on my new ISP, disabling IPv6 on the router helped. Really interesting it seemed to affect only android (S23, S21, Google Home and Shield TV) but not windows, IOS or Mac.
