hero wifi dropping out

Is anyone else having issues with the WiFi stalling and having to reset it, even though signal strength shows as excellent?
It's not a channel interference issue as I know what channels are in use, plus its doing the same on 3 different networks where other devices work fine, I'm using WiFi fixer to reconnect but its still problematic.
What have others found to be the best solution?

Samme issue here. Wifi keeps on disconnecting/loosing the connection and is most of the time unable to reconnect. Have to either turn wifi off/on or choose "forget" and reconfigure the AP my Hero in order to get it to work again.
It´s a Linksys WRT54GX running WPA/WPA2 + TKIP.
Have used an iPhone 3G on the same router for a year now without ´any´ problems.

I'm using WiFi quite often but I don't have this problem with my Hero.
Are you absolutely sure that there isn't any interference? It might be that the Hero is just a bit more sensitive than your iphone.
Today I found G-mon at Market which scans around for WiFi-networks. Perhaps you'll find out that there is a network that's interfering constantly. I've had that a few years ago and then found out that the bus-company uses WiFi on their busses which uses the same channel as I did with my WiFi-network.

Thx for the tip. Checked and no interference.

Also having this problem with a Linksys WRT54G. No WPA though.
I don't trust this router at all; using WPA and connecting a Dell Axim X51v to it in the past used to knock out WLAN on router, needing a hard reset.

same problem here. Wifi is disconnecting randomly within a few meters from the Airport extreme. It also reconnects again...most of the time....without me doing anything.

i'm also having problems with wifi - using a linksys befw11s4 with wep. i've got everythign else turned off - have followed all the instructions i can find here in the forums, and not had any success :/

If you press the Menu button in the Wifi settings you can select Advanced. There's an option there that defines when Wifi is disconnected. If you set this to Never than the Wifi connection will be stable. (At least in my case it is).

Again, thx for the tip but this is not really considered a "solution" but rather a workaround.
I don't like the idea of having it on "allways on". A real battery drainer and it shouldn't be necessary.

I had similar issues with my wifi (Linksys WRT160NL) until I installed "Wifi Fixer" from the market on my hero. Since then wifi runs without problems!

I had similar problem, Linksys WRT54G v1.0 running fairly old (but latest available) Linksys firmware, with WPA/PSK.
Yesterday, re-flashed router to Tomato (based on HyperWRT), setup for WPA2/PSK(AES) and now all is working perfectly, no problems at all.
So looks like some incompatibility between the Hero and the Linksys firmware, for WPA.

Well, I'm running the latest firmware for my router but have now done some other configuration changes and it seem somewhat consistent with your findings.
Previously it was running in a "WPA, WPA2 + TKIP" mode but it has now been working flawlessly since I change it to "WPA2 + AES". Hence:
- WPA2
- AES
=
- WPA, WPA2
- TKIP
=
Info, update on the router: I'm having a WRT54GX, not WRT54G.

interesting; I had no choice but to upgrade, as the newest firmware for the v1.0 WRT54G doesn't - I believe - support WPA2.
Since I had many other wireless clients working fine with WPA (not WPA2), but not the Hero, one wonders if there are some WPA bugs on the Hero that get tickled by older routers, or just that the Hero is being less lenient than other clients.
glad yours is better too, anyway

I found that wifi performance and stability on the hero improved a lot when I changed my AP from dynamic 802.11 b/g/n operation to 802.11g only. I've seen other boxes with linux having similar issues with this AP (D-Link DIR-655), which points towards a driver issue. Wifi works better on Linux kernel 2.6.30 and later on notebooks so things should improve once HTC produce a build that include a more recent kernel. Wifi was quite a headache on notebooks too with the drivers in kernel 2.6.27.x that is included in the current hero firmware.

I have same problem - frequent line drops whne full strenght signal shows
I also have a Linksys WRT54G - never had any problems before.
tried wep and wpa -no difference.
Also tried some "always On" utility from the market place, it only helped reset it quicker.

As stated above, mine got more stable when fixing router to WPA2+AES but I now realize that I still do experience connectivity issues, although less frequently then before...

i don't think this has anyting to do with the router. I got a router from HUAWEI,forgot its brand, but not linksys for sure. I've tried the university wifi as well. they all have the same issue.

Mine is working great with a Belkin.
Looks like a problem with the Linksys firmware.
Anyone tried a firmware upgrade on the router?

Indeed, if you read up just a few posts, you'll find that question answered

that said, although things seemed initially to get better, I'm still seeing regular drop-outs with the upgraded router, and now still with the Hero upgraded to the HTC 2.0 ROM.
I do note that it seems to drop most when I'm sitting quite close to a different strong wireless client, e.g. a laptop. Perhaps the Hero just isn't a strong enough signal, and gets swamped?
Anyone else notice a correlation between dropouts, and proximity to other clients?

Anyone else having issues with wpa2?

I factory reset my phone and tried a different google profile, finally I tried wep 64 and was able to connect and router, if I use wpa2 it will not route, anyone else having that same issue should I take it to a verizon store? Just did some more research looks like it has problems like the droid x where you have you use wpa instead of wpa2, not very happy with this at least I get 3g in my apartment, wonder if it will ever get fixed though.

Using WPA2 here with no issues. Might be your router? Try to update your routers firmware for kicks and giggles.

It's up to date, everything I have been reading through google searches says it doesn't support AES only TKIP.

Not sure then man. I have mine working just fine via AES here.

Are you sure? My router works with both and if I set it to AES only it stops working and won't route, now I have it set to work with both and it works.

Help with fixing Wi-Fi

I have reached my wit's end trying to resolve my problems, so I'm posting here for ideas on fixing this, any input is appreciated!
When this started I was on stock, rooted, ICS 4.0.3 and had been for months. My wife has a nexus s with the same config and hers works fine.
Last week, my daughters sidekick 4G stopped having wi-fi internet connectivity. I turned her wi-fi off, then back on and it was fine and has been ever since. Later that night, my nexus did the same thing, the same procedure resolved it. Ever since then, my wi-fi will only work for 1-5 minutes after turning the wi-fi on. This is the only thing I can think of that changed that could have caused this. This was the first night we connected her sidekick to wi-fi.
The wifi symbol is up there, it'll be blue for up to half an hour, but won't have internet connectivity for long. One thing I noticed pretty quickly was that even though the grey wi-fi symbol is there, I can't access the router settings at 192.168.1.1 from the phone. I thought the grey wifi symbol still indicated I was connected to the router still, but it's not working. Each time this happens, I can turn wi-fi off, back on immediately and it'll work for 1-5 minutes. It appears that the more I constantly use it after turning it back on, it seems to maintain connectivity longer.
Last weekend, just after these issues started, I visited my sister and my phone operated on her wi-fi all weekend just fine.
When I came back home, my problems started immediately.
Here's what I've tried in pretty much the order I tried them:
I started by uninstalling avast, facebook, and autostarts
selected "Forget network" in access points screen and reconnected
Factory reset
Wipe dalvik cache & fix permissions
see if it worked without sim card in (it didn't)
flash GB broadcom driver
Switched router channel from 6 to 1
flash stock 2.3.6 (wi-fi problems still present)
flash OTA ICS (still had problems)
flash stock 2.3.6
flash OTA ICS
re-root
Flash PixelROM 1.60 LiteTouch
factory reset router (No wifi problems on using open network and default SSID for 30 minutes!)
resetup WPA Personal security and rename SSID same as before
Worked for another 15 minutes or so after this
flashed stock 2.3.6
flashed OTA ICS
re-rooted
Restored nandroid backup - quit working after this step
Factory reset router - worked for about 15 minutes, I decided I was ok so I setup security and SSID as before, then it quit working again
flashed PixelRom 1.60 LiteTouch
flashed stock 2.3.6
Flashed OTA ICS - THIS time I did not restore my google backups from the cloud, fearing that this was somehow restoring something that was causing me problems. It did not help.
Changed SSID on my router and reconnected phone
I have spent countless hours trying to fix this. I don't believe it's the hardware because the router factory reset seems to help quite a bit, works fine on unencrypted default router settings, and it worked on my sister's wi-fi.
I have nmap and wireshark and have a basic working knowledge of them. I have adb setup and usable on my computer. I also have dd-wrt installed on my router and have for years. Is there any kind of IP or hardware logging I could perform with these tools to help figure out what's going on??? ANY help is GREATLY appreciated!!

Well i'm no expert with any of this, but it sounds more like a router issue.. If both your sidekick and nexus have the same characteristics of failing wifi, it cant be the devices..
If you've already reset your router and it does the same exact thing, maybe it is something wrong with the router itself. You said it connected fine at your sisters house, so it cant be any hardware within the phone.. The only thing I could think of is maybe try a different router in your house to see if it works? If that helps get rid of the connectivity issue, then you can just get a new router and be happy with the wifis

I don't think a *hardware* problem with the router would only affect 1 device connecting to it wirelessly. I would think that kind of issue would affect all devices on the network.
Which makes me wonder if there's a setting on the router that may be causing it somehow, or some combination of packets might somehow cause the router to block my phone.
But again, I'm open to ideas here and I appreciate your input. I think getting another router will be my next step if I don't hear anything better by the time I get my next paycheck.

Ohh, I thought you had said that both the sidekick and nexus were having problems connecting. My bad.
But yeah have you changed any settings on it lately? Or messed with anything related to the router? Some setting may be kicking your device off after 5 mins, maybe some frequency setting or something dumb like that, I have no clue.
I know how it feels to have funky wifi, so I was only trying to help. good luck

Have you removed DD-WRT from your Wireless Router and back to stock OS? I had a Linksys router with DD-WRT and after about 3 years it started working so weird it became useless with any device. Had to buy a new one.
BTW, are other devices connecting fine to this router?
As swamp goblin stated, I would try with a new router.

It sounds like an issue on your router (or AP) with mixed client settings. I have had this issue with an old Netgear AP.
Try forcing "WPA2 with AES only" if all clients support it, otherwise force "WPA with TKIP only". If you have mixed B/G/N devices, force the fastest mode that all devices support. I use "G only".
Then remove and re-add the router on all your devices.
Also check for router firmware updates, and if you use DD-WRT firmware, find the Wiki page for your model and revision and use the suggested build there. The DD-WRT database they have is a mess and should not be used!

I haven't removed it. I thought I had a model that couldn't go back to stock, but I WILL be looking into this. The other devices connecting fine are Sidekick 4G, Wife's Nexus S, Acer Aspire one, HP tx2000 laptop, and my wife's HP laptop. I also have my satellite receiver connected via ethernet.

THIS FIXED IT! I tried it first since it was the simplest solution and I've been 4 days with no loss of connectivity since I changed it to AES only, which all my clients do support! Thanks so much!

[Q] Wifi issues - constantly toggle

My wifi drops on a consistent basis. I toggle wifi off and right back on, and it kicks back in. This is with stock acer and reflexxx. Stock kernel and one of ezterry's(sp). With both dhcp and static set.
I'd blame it on my router, but at any given moment there are about 6 other devices pulling off my Wifi, and none have anywhere near a similar issue.
Why does my acer's wifi hate me?

RE-FLEXxx and FLEXREAPER got a dhcp patch in them , so it should prevent that problem you have.
You say you got it with stock ICS also and that doesn't got the dhcp patch so if you ask me it is a router problem. Did you try with only one device connected to your router and not 6.

I've considered it's my router. Unfortunately, my cable modem also serves as my wireless router -- provider requires it for 50mbps connections. I've lost my power cord for my old router, and purchasing a new one just to test a theory just doesn't sit well with me. And, unfortunately, things like my HTPC require nearly constant internet.
If no one else has this issue, and you, who seem to be somewhat of a god of acer development, think that it's my router or specific to my individual tablet, then c'est la vie. I shall trust your judgement knowing that there's not much I can do - software wise - to fix things.

If it happened on stock ICS only then I would understand due the dhcp bug.
But my rooms and ezterrys from got the dhcp patch build in to prevent the problem you are having, so on the software side there are no more options when you use ezterrys near stock from or one of mine.
I never have wifi problems and I constantly stream HD movies to my Sony blue ray player in the same time my tablet is connected and so is my phone.
In a rare situation maybe once a moth a need to restart my router and it is also a cable router to my pc with wifi host access for my friends if they pop in. So it is very busy all the time.

Wifi won't stay connected (not D-Link problem)

My phone has problems staying connected to wifi. It's often disconnected and has to reconnect when I wake my phone up (even though it's set to not turn off during sleep) and it'll disconnect and reconnect sometimes even when the phone is awake. I've read about people having problems with D-Link routers, but none of my routers are D-Link. The problem seems to have improved a lot after I flashed my modem to the MDL modem, but it still comes up. Does anyone have any solutions or would anyone know what could be causing this? I'm currently running the Wicked rom but I had this problem even when my phone was completely stock. Has anyone had this problem go away after switching to an AOSP-based rom?

I still have this problem, it disconnects and reconnects minutes later. I am on stock, stock kernel and rooted. could it be a root problem?

It can't be a root problem because I had this problem even when the phone was completely stock. I'm wondering if it's a TW problem, which is why I asked if anyone still had this problem after switching to AOSP (the Wicked rom I'm running now is TW).

If it were me, I would try a different modem, but thats just me.

Is there a thread with the available modems?

Just because it isn't a DLINK wireless ap doesn't mean you won't issues. All the consumer-grade wireless routers/ap's share a narrow range of chipsets made by broadcom, atheros, etc.. So, the brand has nothing to do with it.
I would suggest getting a logcat if you can or try another wireless ap somewhere else. I've got a TPLINK wireless router with OpenWRT flashed, runs flawless.

I never said that only D-Link routers have problems. There's a well-known issue with D-Link routers so I wanted to state up front that I don't have any D-Link routers in case anyone wanted to suggest that it could be the cause.

He said the option was only available while originally connecting and setting up the connection for the first time. Maybe you can try to delete the wifi connection all together and then let it re-detect and go through the set up process again...if that is an option.

My phone was doing this on my friends router but not on my home router. He searched google & found something stating that the S4 dont like routers with AES encryption for the security. He changed his router security to TKIP+AES encryption & the next time I was there wi-fi stayed connected with no constant reconnect problems. Buuuut, my home router security is just AES & I have no issues connecting to it, yet at least. Dont know if this will help anybody else out but its worth a shot to play with your routers security settings.

I thought I had an issue with my I337 S4 do the same thing.turns out my phone was just bouncing around trying to connect to 6 other open WiFi signals I've used

So just to give an update, I tried installing another router in my house as an access point and the phone has no problems staying connected to it, so there's definitely something that the phone doesn't like about the other routers that I'm running. I'm reluctant to say that there's anything "wrong" with my old routers because no other device had a problem staying connected, but if anyone else experiences the same problem, changing routers/APs could work. Fwiw, my old routers had Broadcom chipsets while the new one has an Atheros chipset. I'm going to try updating the firmware for the old routers to see if it helps (I run DD-WRT and Tomato on all of my routers).

I'm having the same constant-disconnect issue as well and searching for solution.
I'm rooted, on stock rom and cant find any "key management" option at initial connect. Issue was happening when unrooted as well.
No issues when connected to router at work, but have connected two other, albeit older android devices to home router without issues.
home router is dlink dir655

WPA/WPA2 decreases the bandwidth of the router. WPA2 will support a full 300Mbps link state. So yea, they are different, but it may not fix it.
I have a Cisco EA6500, so I'm connected to the AC 5Ghz band, and it works flawlessly. WPA2 Personal

My bad on typing WAP instead of WPA.
Doesn't sound like fully opening up the bandwidth will fix it.
Has something to do with how the phone manages the encryption keys?
