Wi-Fi Issues.

Hi, I got the HTC desire during the week and all going great so far except issues with connecting to my Wi-fi at home.
On initial setup i had it scan for my wireless signal but had to manually enter it, network is not hidden. 3 laptops, PS3, PSP, DS all have been able to see it and connect in the past. Anyway, connected through WPA and was able to connect to the internet and market fine.
The issue is it keeps dropping the connection, signal bar stays as if connected but all pages timeout. turning the wireless on/off does not resolve, sometimes turning the power on/off will sort it, most times not. I drove to work last night, 25km and it said i was still connected to a network untill i disabled the wireless on the phone in the carpark !!
I have trawled the net and have come across known issues with other HTC devices and wireless networks but most of the fixes i tried have drawn a blank so far, bar hard reset.
Unsure if it is settings in my router or the phone. One thing i did notice is when it was connected and i went to the settings>wireless and networks it was smooth like the usual progs on the phone, but when i cant connect and go to the settings it is serious laggy.
BB is Eircom, netopia router.
Phone is Vodafone.
Any other info needed just ask, could do with a fix for this before i pull my hair out.
edit: downloaded a wifi analyzer app and it says my signal is very weak, even sitting on the router, it is either the router sending the wrong signal or the hardware on the phone i think.
Anyone have to chage their wireless settings on the router to get the desire to connect ? If so, to what ?
Update.
powered off my phone and ran the wifi analyser again, same thing, -98db.(red, no signal)
powered off the phone again, and was hitting -40db sitting on top of the router and ~ -70 2 rooms away(green/yellow) and internet pages were flying, this is what is happening, may stay for 10 mins and go again.
Another update:
I had a good connection so changed the sleep from 1 min to 30, checked the sig strenght every 15 mins, surfed a few pages and all fine. Changed the sleep back to 1 min, let it sleep, came back 5 mins later and wifi dead again. this leads me to taking the router out of the equation and phone based issue.

Wifi issues
Hiya,
I had exactly the same problem with my desire. It is on Orange UK and came withall their crud on it. I spent two days playing around with the router settings and phone settings. I could connect to the router but not use the internet. In the end I followed the links on here to erase the orange crud and install a generic rom. After that the phone connected to wifi internet and telephone internet and switches between them without any problems whatsoever. I did wonder if it was a ploy by the telecom provider to get you to use more of their online data rather than over wifi.

Galaxy Note 2 Wifi issue

This is pretty strange so I thought I'd check here with people.
I got my new Sprint Note 2 today. When I was at home it connected to my wifi network and worked fine. When I got to work I connected it to our wifi network and the internet won't work. If I turn off wifi internet comes back.
Here's the kicker, I have my old iPhone right next to it connected to the work wifi network and it is connected fine to the internet. This is definitely going through wifi as I no longer have a data plan on that phone.
I checked with our IT admin who said that there is no need to "accept" a device on our wifi network. He also rebooted the network for good measure. After both phones lost the network (from the reboot) and reconnected the same thing happened. No internet from my Note but internet works fine on the iPhone. Restarting my Note doesn't fix the problem.
Any ideas? Thanks.

I have the same problem. Need help too.

Is the wi-fi sleep mode on?

Very odd. I've had no such problem at home,work or university

My network admin created a second wifi network to connect to (I guess our router supported it) and when I connected to the new one I got internet.
If it helps others try and solve the issue he tried pinging the IP address that my phone was using and said that he could only send information but not get anything back.

Try changing your wifi channel config in the router.

Hi, I've got the International version N7100 and experiencing weird wifi problem. I have tried to reset my wifi router and use static IP but it doesn't solve the problem. Btw, the problem is whenever I connect my Note 2 to wifi it would lose connection after a while then messes my router and connection of my PC to router as well. Never had this issue until I brought the Note 2 home a week ago. I had to restart my router and turn off my wifi on Note 2 for everything else to work. My iPad, iPhone and PC are all doing fine when Note 2's wifi is off.

I used to have terrible problems with my Virgin Superhub which all went away when I changed the security settings to WEP hexidecimal from WPA2-PSK (AES). Laptops and phones would have intermittent connections all the time which a reboot or channel change would sort out but only temporarily. Give it a whirl.

I've been experiencing the same problem. It's especially annoying when I try to download big size apps on Google Play ( > 1 gb) because it will stop any moment and i will have to re-download it over and over again. It never happens when I connect to school wifi but it just happens when I connect to my wifi at home. Weird. Nothing is wrong with my wifi at all because my other computer is always connected 24/7 without any problem.

I have a similar problem on Omega Ron v5.0 with latest Andrei kernel. The phone gets stuck sometimes in getting IP address part or have disconnects. It's annoying.

Afraid not.
I did that after other efforts failed but still have to go through same issue every now and then. This is not a permanent problem but something that occurs at least once a day for me.

Also having Wifi issues with GN2 from Sprint
I got the GN2 on it's release date (this past Thursday) through Sprint. Got it home got set up, connected...everything worked beautifully.
After a couple of hours, downloading apps etc. I noticed it had stalled. Turned off WiFI and used the network to finish. Turned back on WiFi and Voila, action again, but a few hours later it stalled.
I first made sure all of my settings were in agreement. No sleep mode or anything like that was enabled. No power saver either.
Couple hours goes by, WiFi connectivity stalls (even though it shows a full signal) I contacted TWC and made sure it wasn't the modem/router. I changed the wifi channel, tinked with the bandwidth... everything worked...an hour later it stalled. Called Sprint they said I had a dud, took it back, exchanged it, got the new one... SAME ISSUES. YEsterday I connected to my Church network HOPING it was an issue at home, but not so. After an hour on the network it stalled.
Contacted Samsung today and they have had no complaints according to them so i said I'm happy to be the first... If anyone finds a fix please let me know.
PD

Do you have any solution yet? I have the same issues with 2 different networks. I already contacted Samsung, but they only say I should do a reset of my device and read the setup instuctions for wifi. I'm still in contact with Samsung and hardly try to get a solution.
Stay tuned, I'll post any news I can get.

I'd prefer it to work with the stronger encryption of WPA2 rather than WEP.

OP: it will be great if you could add a poll to the thread as that way we can see whats the percentage of users are experiencing this issue,
Thanks

I had this issue with my S3, but never with the Note 2. What i did in that instance was reinstall the OS and that seemed to have fixed the issue. Hope this helps!

Same issue here. Connect wifi and I'm able to hold connection for as little as minutes at times. Turn back on 4G and I'm fine. If I re enable wifi straight after it works intermittently. This is true of both my home and office wifi. So I'm lead to believe it's the phone.

Hi,
Almost the same thing here. everytime I go out of my home and comeback the wifi network seems to work but no internet access. I have to stop and restart wifi then it works.
very strange issue. ok I have a work around but I'm going to open a ticket to Samsung.

Same issue - connects for about 30 seconds
I've tried on different routers. Other devices (iphone, ipad, S3, etc.) all work fine. Sees the wifi network. connects, then disconnects and TURNS OFF WIFI. I can't figure out how to go to service mode to see if this is a timer issue. I've tried on both G and N networks. using a verizon fios, actionteck router (and netgear). Also, will not remember the password credentials. tried router reboot and fidling, etc. Driving me nuts. any suggestions ???

[Q] Wifi is connected but no traffic, WTF?

I thought at first my router was having issues, but that is not the case. I have confirmed zero router issues by using 3 laptops and 2 other phones (Samsung units) to connect to anything I want.
If I connect using my M8 (Verizon), it connects with no issue but I have no real internet connection. The signal strength is -40 so that is not the issue.
I have tried multiple restarts, multiple networks, and multiple SSID's. I even tried forcing it to 2.4 or 5 Ghz and nothing at all seems to work.
Is this a known issue? I am coming from a long line of Samsung stuff so I am not up to speed on the quirks with HTC stuff. Your assistance is appreciated!

Stock, custom ROM, etc?

This is a stock ROM with weaksauce root and nothing else.

Ok, so I just connected to the wifi at my office and it appears to be working just fine, but it took about 15 minutes form my phone to recognize that the network even existed.

I am pretty sure this phone is just a piece of crap. About 2 hours after my last post it started doing the same thing (at work). I just got home and did a 100% fresh reset of both my router and my phone to eliminate any possible configuration issues and it shows that it is connected on the phone, but the router is not seeing that it is connected... how the hell does that work?

Since you've determined its a piece of crap, sell it and get yourself a iPhone. Why bother trying to get it to work.

When you connect to your router what details does it give in the phone WiFi settings for that connection?
Also which router do you use?

[Q] Wifi issues

Hey guys,
So all of a sudden, my wifi is searching and not connecting in a campus setting. My Samsung Galaxy Note 10.1 2014 is still connected to the same wifi my Note 4 was. I have tried rebooting, removing battery, shutting off and on data and wifi, and airplane mode. Nothing reconnects it. Also tried forgetting all networks since there are 5 when searching for networks it finds and reconnecting to one, still no dice. It's been 4 hours, still can't reconnect. Any ideas?

Have you tried to forget the network and then ADD it with + Add Wi-Fi network? I actually had an issue playing with a Galaxy note 10.1 2012 edition, I turned my hotspot (sprint note 4) on and named it the same as our current network (was showing how open networks aren't always the network they say and anybody can create a Starbucks-Guest network.... I used starbucks-guest because I didn't want to put my schools on here). The tablet didn't see the network even after reboots, but when I added the network manually it connected right away. Also was this connecting to the same access points or different ones on the other side of campus?

Yep tried forgetting, re-adding the wifi spot and nothing.

I've been having wifi connection issues since day one of getting this phone.
Not sure if I have the same problem.
But at least once a day, it seems the phone can no longer make a connection to my wifi.
The only solution is to either just power off the phone and restart or do what Sprint asked me to do.
Sprint said to try and reset the network connection information by dialing ##72786#
The phone will power off and then restart do some background stuff and then power off again and restart.
Once that is done, all is fine.
I've never had this happen on any other of my Android devices. I even use a static IP with my phone setup.
And yes, I have tried just using the default of DHCP.
I had thought it was my router (Asus RT-AC68U) which transmits both 2.4ghz and 5ghz. I have both setup and I try to use 5ghz the most.
I did upgrade the router software because I was one version behind, but that did not fix anything.
Also, I had a Sprint femocell in my house (provided for free from Sprint) because I had bad signal issues years ago.. But because this phone uses LTE and now it seems the phone comes with built-in WiFi Calling. (Means instead of using the cellular network it will use my network and ISP to make Sprint calls, all voice and text messages come through normally, it's basically a built-in femocell).
I returned that, whoops still in the box, need to get that mailed out fast.
I'm not sure how widespread this issue is, but I suspect it's bigger that just the two of us here. And if I'm in the wrong thread, please let m know.
Thanks

Mesh WiFi issues after latest update

My wife has the S8 and I have the S8+. After the latest update (July 9-10'ish) both of our phones are having problems with our Mesh WiFi, but not our non-Mesh WiFi. We don't have issues with the connectivity to the actual WiFi, that always stays connected, but every few minutes, we'll get an exclamation point next to the WiFi signal meter, and our Internet connectivity drops. When I check WiFi connections during this time, it shows "Internet may not be available". Then, after 1-3 minutes or so, it's working fine again. While this is happening, none of our other devices have any problems with Internet connectivity.
T-Mobile had me boot into Safe Mode, and the problem didn't happen at all in safe mode. So, I did a master rest, and with just factory apps installed, it was happening again. T-Mobile asked me to wipe the cache partition. While trying to boot to that menu, my phone went into a boot loop, then after trying several different button combinations, it just turned off and wouldn't power back on again. So, T-Mobile sent me a replacement. Since receiving the replacement, I have not installed the update, and I have not had the problem on my phone at all. But, there's still my wifes phone. T-Mobile tells me I'm the only one having this problem, so they don't know what the solution is.
Our Mesh WiFI system is fairly new, so I kept the old WiFI active as a fall back option. There are no problems when connecting to that SSID, so I'm thinking the update has caused some issues when jumping between access points on the mesh system. I was also thinking maybe it's a double NAT issue, since my modem doesn't have a true bridge mode option. (My modem hands my mesh WiFi router a 192.168.1.xxx IP, but my devices that connect to the mesh WiFi get a 192.168.0.xxx IP) I tried putting the Mesh WiFi in the DMZ and making sure it gets the public IP. That didn't work. The WiFi manufacturer had me open ports 500 & 4500 to the WiFi router. That didn't work.
Does anyone have any other ideas for me? At the point, T-Mobile is telling me that it's my WiFI because it doesn't happen when connected to the non-mesh WiFi. But, it didn't start happening until the last update, and it's not happening on my replacement phone. We rely very heavily on WiFi calling, so this has been problematic. Obviously I can connect my wife's phone to the old system, but we don't get full coverage in our house from it, which is why we went to a mesh system.
I welcome and appreciate all suggestions.
Thank you

I have the same problem with my non-mesh Google Wifi router occasionally. it's annoying.

I'm having the same exact problem with my S8+ and my netgear orbi, all was good until about a month ago, and I've tried pretty much everything, and the exclamation point still comes every few minutes. I can't wait to get rid of this phone honestly. And I've had EVERY Samsung phone to date, and this one has given me the most problems by far. I am on my 5th S8+. HURRY NOTE 8!

Running Luma mesh network... Have the same issue on my S8+ after the update...

Thank you! I just changed that setting. I really hope that works!

Other fix is enabling guest network on your router. It worked for me with Netgear Orbi.

I have an orbi and the above fix didn't quite fix my troubles. After enabling guest mode, then what? Use guest mode? Or does just the act of enabling guest mode change something? Thanks in advance.

Wi-Fi Verbose Logging
Yep! This is a problem the carries and Samsung have chosen to ignore so far. I have the exact same issue with two S8's in my household. Everything, all devices, LG, Apple, HTC, Google, Amazon, PC's, etc., including the S8's worked on our mesh wifi network until the two S8's took on the latest update. After that point neither S8 device would consistently work properly on the mesh network. While all other devices, including a Note 5 and Samsung Smart TV, among a plethora of other devices, continued to work flawlessly. It is definitely tied to the latest update on the S8 devices. I reset the wifi, the phones, etc., including factory resets but that did not solve the problem. Verizon sent 2 replacement phones and we have not allowed the latest update to load on the phones and the replacement phones are working perfectly! The latest software version that screws up mesh wifi connectivity is: NRD90M.G950USQU1AQG4. Beware. So far, neither Verizon or Samsung will acknowledge the issue. Only after hours of trouble shooting and persistence on my part about this issue being a well documented situation in on-line forums did they respond by saying they found one case similar to mine but they did not see this as a wide spread issue. Well, for anyone with a mesh wifi network, this is a big issue and irritating as heck! Come on Samsung! Own up to the issue, support your customers, and fix the problem. The evidence that there is a problem at this point is pretty convincing. All one has to do is go on-line and search the issue and bam, there it is. All somebody at Samsung has to do is take an S8 load the latest update and try it on a mesh wifi network. Really try it that is... It work at first but as soon as the mesh network moves the device to a channel or frequency that is less congested, the device will lose connectivity. Sometimes it is sporadic but eventually it becomes a more persistent problem to the point of uselessness. Either put out a patch or push out the wifi portion prior update for us to revert back to. Don't call us liars and ignore the issue. Hard to achieve customer loyalty and retention with behavior like that. I've already had to muddle through the Note 7 fiasco with the 3 recalls and final discontinuing of the device itself. Samsung, don't leave me hanging again.
UPDATE:
Turning on the Wi-Fi verbose logging did not solve my issue. It seemed to work at first. However, after a few minutes it said it was no longer connected to the web when trying to load some very common url's. However, this time there is no "!" next to the Wi-Fi signal on the S8. It now just stops working. Wish I hadn't let it update on the replacement phone. Again working just fine before the NRD90M.G950USQU1AQG4 update.
Help....anyone!?

After enabling guest-network, forget the main SSID and connect to guest-network. If you "allow guest to see each other..." you will be able to see other devices, like printer, Sonos, Roku, etc.
