WiFi: Conected but VERY slow

I'm pretty happy with my new HTC Hero, but I'm having a lot of trouble with the WiFi connection. I connects fine and shows "good" or "excelent" signal strength on my home network. However the speed is very slow and if I go to Android Market it loads the different apps very slowly an looses connection often: It says "No connection" and I press the "Retry" button...). It is not just a problem i Android Marked. Loading pages in the browser, facebook etc. is extremely slow when on WiFi. When I'm using EDGE everything is A LOT faster and I don't get "A network error has occured. Retry or cancel...etc.".
I have tried different settings on my access point, but nothing seems to help. I have (tempoarily) disabled encryption, tried swiching channels, using B instead og G setting, and manually setting: Gateway, DNS etc... In the end it got a bit frustrating so I tried a factory reset. But WiFi is still very slow. If you have any suggestions to what the problem might be I would be very grateful.

I had a similar problem with my AP (D-Link DIR 655) and tried to set it to use the same communications setup as another AP that worked properly. Whatever I did with encryption, keys and channels made no difference on my AP. The solution on this AP was to set it to 802.11g only (it was b+g+n), and it has worked fine since.
I do however suspect that there may be some serious issues lurking in the linux kernel that is used on the hero (2.6.27). Wifi was a nightmare on that release with notebooks too, and core parts of the wifi-stack has been replaced since. I wouldn't be surprised if we see a significant improvement in wifi-performance whenever there's an Android release that include a 2.6.30 or later kernel.

I have been having the same issues but my wifi didnt work with the browser, or youtube. I downloaded Opera mini and wifi works fine. With factory browser i can go to google and it will load and search but once i click on links found it hangs and wont connect. I am so frustrated my sim is going back into my iphone 3gs until an update is released this sucks big time

It is a bit disappointing if this is a general issue, but I'm glad to hear that I'm not the only one with this type of problem.
Maybe this could also be a HTC-issue? I remember my HTC Tytn II where there was a slider where you could choses between "performance" or "battery saving". I remember that I couldn't get the WiFi to run properly unless I set it to highest performance. I consumed more power but it worked with this setting.

On my Hero, the HSDPA connection is for some reason faster than my ADSL2+ (24Mbps) connection. Rather odd..

Same here. The 3G/EDGE is a lot faster than my 20 Mbit ADSL. It makes no sense

Why does it take so long to make a connection to my router via wifi?
This can sometimes take 10 - 15 minutes before I have a connection.
With my windows mobile device this takes only a few seconds.

I'm experiencing the same issue on my Hero (with updated HTC firmware). I've also tried playing around with my routers settings to no avail. My Hero is basically useless for browsing on WIFI.
I'm curious, does anyone running an alternative rom experience this? If not I may look into rooting my phone..

Root your phone and do this
echo 0 > /proc/sys/net/ipv4/tcp_timestamps
It will fix it.

you've had 57 posts and dont know what rooting is;p aha (not trying to be a ****, just found that funny:])
when you root your phone you gain root access and can do just about anything, like install apps that need root access! there are guides in the dev section on how to, and if you do a search there is a thread on what root allows you to do!
i dont know if that command will fix your problem though, sorry!

I've been a "windows mobile" user for a long time.
I know what "root access" is in the general Unix environment.
But I don't really know how it works on the Android OS.
I'm more of a Windows guy.
It's my first time messing on Android, I got tired of Windows Mobile.
frem

Just my humble opinion. This is a problem that should be fixed by htc.
If rooting fixes it it's good, but it can't be a requirement to get it working properly.
I mean you buy a phone with wifi, you expect it to be as fast as your provider is... Getting less is just not getting what you paid for.
Has anyone mailed HTC about this problem? I hardly ever use wifi but tried it today
and indeed my hsdpa is lot's faster than my 20mbit connection @ home.

Help us pleaseeee

That pretty much cut the speed in half for me.

Seriously the wifi issue is a big problem for me. I don't have a 3g unlimited plan.
Basically when i activate the wifi i start a application like update weather or check a webpage or update tweets, it works then connection drop and i can't connect to anything.
I have to deactivate wifi then reactivate to get like 40 seconds surfing and downloading apps on the market.
IS everyone having the same wifi problem ?
It happened on every access point not just the one at my place.
Please help me, is it my phone that has a hardware problem ?
frem

you gotta think of it this way...
most people who dont have problems arnt gunna make it to this thread because there not searching for it! So your mostly gunna get replys saying "same here"
so im guessing most people dont have this problem.. although it could be a specific rom on a specific carrier or something... see if you have anything in common with other people with this problem, if not, maybe it is hardware

WiFi channels
Have you tried changing the wifi channel in your router settings in case there is interferance with a nearby router on the same channel? Although you would experience slow wifi on any wifi device (laptops)..but worth checking.
I've just done a speedtest on my phone using the speedtest.net app and do get just over half the download speed on my phone (5-6mbps) opposed to my pc (wired 9-10mbps) and laptop (wireless 9-10mbps). So knowing my wireless is set up correctly, it does show some loss in speed with the hero. See how much of a loss you get?
Adam

Thank you for your reply. I think i figured it out. I am at the countryside right now and im connnected on a diferent acess point and it's working perfectly i'm actually writing this post in WiFi mode on the hero. So the problem is from the other access point i tested. i already tried changing the Channel number. I use a french provider that use access points called "freebox"

FYI the problem with the hero and some wifi access points is well known and is being forwarded to htc by Vodafone.

Well, bro I've just bought this fone two day back, no not quite comfortable with its functionality and all that stuff.
It would be highly appreciable if you could help me

I would if I could, but with this amount of information all i can suggest is to do a reset.

Please tell me what should i tell you.
I simply connected wifi and it got conected......... it show in the settings that wifi is connected....... now, i trying to access net via the default browser which comes with galaxy 3, but it is not able to open any page. even I tried to connnect gmail it is also not getting connecting.......showing connection error............
this is the real problem

Does this happen on only one wifi network or on more networks? If its only on one it might be a network specific issue, like having to set DNS, or something else. If you have only experienced it on one (even if you only tested on one) what can you tell me about the network; is it your home network, school network, work network or whatever, what kind of protection it has.
Tell me us anything you can about this situation, since we cant conclude what the situation is, is it a problem with the phone, with the wifi network, aliens disrupting your phone to get some laughs out of it. It could be anything!

It happens with all the network, it tried accessing from office as well

I am trying to access wifi from my home network....... tried from office as well......
both the connection are not protected....... though I am that technical for such stuff..... but knows that anyone can access my internet. I just realized this, when one of my friend was browsing net on his laptop from my wifi connection
even my phone says that wifi is connected. but there is problem with browser... none of app is connecting....... not even FB, games or any other application

Before resetting try to reboot the phone.

done, still the same problem

Which rom do you have ? have u flashed any ??

do you have a data connection turned on?

Hi.
I have wi-fi problem too. Just appeared 2 days ago. Wi-fi was working normally at my friends house and after i've selected "forget" on his wi-fi and now i cant connect wi-fi at home. It says "unable to scan networks". In phone status there is Wi-Fi MAC address unavailable. If you have an idea just write it down!
Didnt try factory reset yet, hoping you have better idea!
Sry for bad english..

you have to be roooted:
delete or rename(i suggest an extension change with the date) bcm_supp.conf in /data/wifi/
I suggest using root explorer, terminal is also an option.
warning, you will lose saved wifi networks/passwords.
you can open the file to retrieve some passwords.
if you have a titanium backup of system data i think you could restore it with that, not sure about it.

I dont care about passwords, will get them easy.
But i'm not that good using Terminal Emulator. What should i write in it to rename/delete bcm_supp?
EDIT : you are my hero! just installed root explorer (really cool apk), renamed the file above and works fine!
If u ever come to Croatia you got a beer

Yup, root explorer is a nice app, I had to do it via the terminal myself a couple of times, not as pleasant as with root explorer.

Have problem using WIFI on school campus

I can pick up the WIFI, and it says excellent connection, but the school requires a login page for you to enter your username and password before you can start browsing.
So after I'm connected, I try opening a browser but it instantly says I dont have internet access. I dont know what to do or how to fix this. Has this happened to anyone else?

If your campus is like mine, you may have to go to the IT help office. Once a year I need to do this to have a clearance installed on my laptop. Havent tried yet for my G2 but I know we support iphones for wifi on campus.

How safe is it to connect the G2 to a open network without security though? Thats what worries me about connecting my G2 to my schools WiFi.

as long as there is no protection on the Wifi it is possible for other users to see what you send and receive on your phone over wifi.

I'd worry more about connecting your computer to the WiFi. As far as open WiFi goes, the school ones is probably more secure than your random Starbucks is, however.

This is how to get WIFI on my campus, maybe yours might be the same
http://www.uic.edu/depts/accc/network/wireless/android.html

The thing is my school network doesn't prompt me for a password.
As of now I have yet to fix the problem. In some buildings, I have no problem using the WIFI. Basically connect to the network, open my browser and it will ask me to input my ID and password and done.
But there are times where I connect to the network, open my browser and it just shows an offline page. I can keep on refreshing, but it just loads the offline page right away, and I can't find a way to input my password.
I've tried bookmarking the input page, but it still doesn't work.
I've also tried copying down the IP and DNS but it didnt work either.. and too troublesome.
For some reason WIFI on android just sucks. My old old sony ericsson phone could connect to the school network every single time. It could also connect to the ad-hoc network my windows 7 laptop send out using connectify.
Yet my new desire z has problem connecting to campus networks and cannot see ad-hoc until i temproot it and mess with the system files.
ironic huh

Really? In my school am able to connect with my g2

Dude the op stated he needed a username and password..so how exactly is that an open network?
Sent from my T-Mobile G2 using XDA App

If it's anything like my school, it will be WPA-Enterprise.
ID will usually be: (domain)\(student ID) where (domain) is your schools domain (ask IT for it) followed by your student ID
PW will usually be the same password you use to log into the school computers.
IT people are usually helpful in getting your devices onto the school network.

This would happen to me on my campus also. What I would do is either keep pressing the back button until the browser exits completely, go back to the homepage(browser homepage), or just reboot the phone/kill browser task. Its certainly not consistent but at least one of those three would solve the problem on my campus.
On the other hand, my campus is in the city so generally hspa+ is faster than campus wifi (sad i know)

Paranoia is a disease unto itself and may I add the person standing next to you may not be who they appear to be so take precaution.

More than likely you have to register your MAC address with the school. Should be done with the computer department (probably via a web page).

this can sometimes be the case, although on my g2 here at Oxford College of Emory University, I never had to go to IT to officially register at all.
something that might work, though. Try not using the stock browser, but instead something like miren, dolphin browser or the like, and set the browser to use the desktop mode. Usually this will bring up the login screen, just like it would as if you had logged in from your laptop. hope that works for you, if not, pm me or hit me up on google talk (same user) and I can try to help troubleshoot some other possibilities.

Wifi Hotspot - Why Gmail?

Hey everyone,
I've tried all of the tethering apps (usb/wifi) and none seem to give my laptop my legend's 3g data connection. I'm running CM7 (new stable version ) and i've been trying to use the built in hotspot to no avail. I can connect fine, even with WPA2 security, and the laptop connects fine (win7), and even shows full bars on the wifi icon in the bottom right of my taskbar, which says "Internet Access" when my mouse hovers over it.
The problem is, whenever I fire up chrome on my laptop, I get a page that says stuff like "Access denied", "authorization required", "You may need to sign in", and just gives no internet.
At first, I thought that it could be my carrier's fault (SFR France), that they don't want me tethering my phone's connection (I have a contract with unlimited data). The weird thing is, I can actually use gmail on my laptop! Yes, fully load new messages as they come, look through my archived messages, trash, spam, everything. Not even offline messages, it's really connected. So why can I access gmail on my laptop but nothing else? Could it be something to do with https connection to gmail or something like that? My phone's 3g works great, and my laptop has no troubles connecting to my home wifi. I've scoured XDA and google, and never figured it all out.
Anyways, thanks for reading!
Michael

Troubleshooting 101:
- first, please try another laptop.
if the other laptop works, then your current laptop has issues.

My bad, I meant to include in my first post that i've gotten the same result with 3 different laptops.

Have you tried pdanet app? That's what I use and it works wonderfully.

yeah man that was one of the first ones i tried. no go for me, same issue (not connection, but internet access).
When I try to open a page, my phone shows that it starts to download data (with the arrows lighting up and the "H" for HSDPA in the status bar). But then stops and my browser says nope.

tried changing DNS, for instance to googles own (8.8.8.8) on the laptop?

How do I change the DNS on my laptop? Don't I need to use cmd for that?
And an interesting new development. Hopefully someone smarter than me understands this:
I've now tried 4 different sites that fully work! The thing is, they're all https sites, which all the other one i tried weren't. Just to let you know, the 4 confirmed funtional sites are:
gmail
google docs
dropbox
android market (in pc browser version, not on my phone)
So its GOT to have something to do with the https...
Any ideas?

Well, I have Windows XP and I don't have experience with Windows 7, but I remember that since Vista the network connections can be set as Home connection or Public (or something like that).
It's a wild guess but maybe the problem with browsing to HTTP websites has something to do with these network settings in Windows 7...
Try to compare the settings in the Home Wifi connection in your laptop vs the Mobile Wifie connection in your laptop, maybe some settings are different between the two.

Thanks for the suggestion, but unfortunately that doesn't change anything. I definitely know what you're talking about, and everytine I connect to a new wifi network I always select home as the network type, so that my browsing isn't restricted. Hence I did the same here, and even tried the public option, but no effect.

Yep I tried usb tethering, same deal. Windows troubleshooting "couldn't identify the problem". It's gotta be something either on my carrier's side, my phone's side, or my laptops side that is restricting hotspot access to http sites.

[Q] Able to connect to many different WiFi Networks except school ones

Hello all.
I can connect my Nexus 10 to my home wifi (password protected), my girlfriend's home wifi (password protected), and the wifi at public places (I've only tried ones without passwords so far). My only problem is when using my University's Wifi. They have one that you use with an account and password, and one that is free (though you need to sign in using an email via a website. Kinda like hotels).
This is surprising to me because I have a Galaxy Nexus running the same OS (4.2.1) and it can connect just fine. When my N10 tries to connect, it says "connecting" for a second or two, and then it just says "Saved" but never "connected" and it never shows a wifi connected symbol at the top right.
I have read multiple posts about wifi problems from 4.2 but couldn't find any specifically buggy wifi problems like this. Have any of you heard of this or a solution to it? Any help would be appreciated!

Have you tried a reboot? Also check to see if your frequency band is set to auto under advanced wifi settings.
Gotta love university security and logins... they can't leave stuff simple

Oh yes. I have rebooted many times and tried using auto, as well as both frequency bands separately.

Hmmm...are you on stock?

Yes I am. Stock on both my Gnex and N10.

I wonder if using a third party wireless manager would help. Search the PlayStore and try one or two. Before you do that, go into your normal WiFi settings and click "forget this network" on the university one.

Hi there,
I work at a University in the midlands and had the same/similar problem. It's to do with certificate revocation in Jellybean (and also the latest ios my colleague tells me). For example on my Nexus 10 I was able to see the network and obtain an ip address but the webpage where you login wouldn't redirect or load. I don't know what Uni you go to but we are advising people to give the IT dept a call and give them your mac address and they can create a fixed profile.
Hope this helps

I'll definitely try the third party app. As for telling the n10 to forget the WiFi, I tried that many times too
Well that's why I mentioned my gnexus because they're the same android versions so if it works on one it should on the N10. I actually work for tech support at my university and my boss couldn't figure it out or suggest a process like you described. Thanks, though!

Oh yeah you did mention your Galaxy Nexus, my bad! let us know how you get on with the third party app. You could try giving your N10 a static or reserved IP if you have access, as a workaround!

Hey guys,
I'm from France and had such trouble with my Motorola Milestone and my HTC HD2 (and friends too with Samsung Galaxy S2 and Sony Ericsson Xperia Active) with my school's network. If it's an Eduroam network, try Eduroam Fixer from PlayStore, it helped all of us except one Samsung Galaxy S2. Give it a try

Make sure you have the EAP set correctly and check if you need a phase 2 authentication. For example, here at UofM we use PEAP for eap and mchapv2 for the phase 2. If you don't have details like these, your tablet won't connect even if you have the proper login.
You will find them at the top of the page you use to login to a secure network.
Hope this helps!

Yes, that is exactly how the secure WiFi is set up at my University, too! What should I do in this case?

Edit: Nvm, Just noticed this was already tried
I had a similar issue with my One XL. It was a frequency issue. I switched it from 5ghz to auto and all was good.

Okay so I found out that my N10 is able to connect to the exact same WiFi network when in another building. I believe there is just an issue connecting to the specific router used at a computer lab. Will update when/if a resolution arises for that lab.
