WiFi poor

I'je just unpacked my desire yesterday.
When i am straight "connected" to the AP, i have full wifi
20cm makes it to ok
1 meter makes it to poor
next room no Wifi
My Hero has good Wifi even next floor and poor outside the building
How can I improve that?

I have pretty much the same problem, very poor wifi access unless I am sat next to my router.
considering adding another wifi router to my home network to solve this issue

I got the opposite ... My HTC Desire has very good wifi access.
Even when I am in my bed room at 1st floor where it can only got 1-2 wifi signal, it is still damn fast. Also no problem in the 2nd floor although the signal indicater is just 1.
The wifi router is located in the ground floor.
When I used my old HTC Kaiser, there is no way I can access wifi from there.
Now, I got wifi all over
So, I think, it could be the way you configure your wifi router. Here are some pointers:
- Set to "g" ONLY
- Set to use non-crowded wifi channel
I set my wifi channel to 6, which it is not being used by neighbors wifis.
There is also an application in the market called "Wifi Analyzer":
http://www.cyrket.com/p/android/com.farproc.wifi.analyzer/
It is free and it is damn good for showing your wifi signal strength and channels etc.
Install that and let us know your situation.

Installed WifiAnalyzer
In my office building (which has plenty WiFis) i only sometimes see our Wifi which as a 7dBI antenna. but this shows with "half -90dbm"
our Linksys Wag160N has -40 when Desire touches the AP and -60 when 1 meter away
How can I set "g only" on my desire?

HTC sais I have to
- have a small distance between AP and Desire
- Check the "angle and how I have it in my hands" between AP and Desire
-enable WiFi
--> I gonna change the phone

The "g" only is setting in your wifi router, not desire.
I am now in the attic and my wifi signal is not that good.
When the signal is -90, I got about 500 kbps (using SpeedTest app), not quite usable, sometimes the connection was dropped.
When the signal is -80, I got about 2000 kbps ... usable
Those are examples on the worst condition at my place and my HTC Desire.

I've had my phone conected to my WiFi while I was in my car on the drive which is 15 metres away.

yep same prob here if in same room of router sinal fine, if i move out of the room and about meters away then i almost loose it will try the HD, but im sure it was the SPV m3100 i could get my wifi out in my street,
Why is the desire wifi so poor ??
its a great phone, but it seems to be going from Desire to Dire

i went to the shop where I bouhgt the desire and they were changing it.
Now I have good WiFi again

The Wifi signal is fantastic, its stronger and faster than any of my other devices connected to my Netgear DG834g (custom)
@pickie, it sounds like you need to replace ur handset

Wifi connection loss an reconect
Hi there,
i have also a problem with my wifi connection. The connection to the router works fine, but every 3 or 6 seconds the connection is lost and the phone reconnects. One to 4 pings to my HTC Desire are lost, then 7 to 10 pings work fine, and again some pings ar lost. Its somhow a bouncing conanection.
I´ve testet the app wifi analyzer and i can´t see any problem - connection strength is around -36 to -40 dbm, so what could it be?
I am using a Zyxel nbg460n, the connection to my notebook just works fine...
I hope, anyone has any idea

Same here for everything you said. -60dBm on 2nd floor right now with router on ground about 90m away. The reason why I predominately use WiFi.

More in general, but I boosted signal quality by switching back to b instead of g.

Yes, i noticed that switching channels improves my pings... but just for a while and just for this time - next day i have the same problem again. switching the channel while my phone is connected helps a bit though - but i guess this can only be a workaround than the solution.
and it does not matter if my phone is in my hand or just lays on the table and the distance to my router doesn´t matter.

I have solved my wifi problems by changing the software on router. Went from pfsense to openwrt, and everything works now.

WIFI Problems

My wifi if being finicky, like not wanting to connect, or even see my home router, is anyone else having any trouble with wifi?

it must be your router.

I was running it with the following:
SSID broadcast off
WPA2 Personal
Mac filtering
I turned SSID broadcast back on and it works fine now, someone else want to replicate those settings and see if they have problems?

I am having problems connecting to my wireless router, my Evo is saying I have a "poor signal" at my computer desk but my computer is showing me at 100% signal. I think its a Evo software thing but thats my 2 cents. I don't use my wifi often with my phone any way so no biggie for now.

I also have ssid broadcast off and I cant get it working.

Hi everybody, So far I love the EVO even without 4g. Anyway after I turned on my ssid I connected okay. I can see the market and find what I want to download. It says downloading but never does. I have downloaded apps with the 3g but I don't have a signal at my home. I always used winmo before and had no problems downloading on my home network. I wondered if anyone had any suggestions as to what I might be missing. I got root okay and have been having a blast but I sure would like to download some more apps while I am at home. Thanks, Rick

SSID broadcast off and no issues for me thus far.

Yes, me too. Sort of.
My Evo shows 1 bar of wifi signal strength at a distance of 8 feet from the router where my iphone shows full bars. I do get decent download speeds using xspeedlabs free but the upload speed seems to cap at 750kbs where the iphone goes over 1mbs with the same test. There is definitely something weird going on.

I am having similar results as far as signal strength. Sitting 2 feet away from my router I am only showing one bar of signal strength and getting very slow speeds. All of my other wifi devices (including those that are on the opposite side of the house and downstairs) are getting signals ranging from "good" to "excellent". Something definitely seems to be up with the wifi.....

I was having wifi issues too. I'm running dd-wrt on my router. Turns out just power cycling the router fixed it. I think I'm going to setup my router to reset weekly.

I get the same issue of having 1 bar of signal strength, regardless of how close I am... even tried on 2 different wireless routers, Linksys-dual band N, and Net gear A/B/G.
I get strong signal from both routers on all other devices, iPhone, iTouch, Touch Pro, Laptops, etc...
I've played with all the settings on the EVO, turning off the mobile data and only having wifi on, changing the encryption settings on the routers... nothing seems to work.
I love the phone, but kinda bummed about this issue.

I have ssid broadcasting turned off and I'm using WPA 2 with no problems.

There is a long, angry thread about this over at HTC's own EVO forum: http://community.htc.com/na/htc-forums/android/f/94/t/2929.aspx
I'm also getting less Wi-Fi performance on the EVO than on other devices in the house.

Using Fresh 1.0.1 rom and also the new Cyanogen rom, with the SSID off, I cannot connect with WiFi, with SSID on, it works fine. Using Cisco/Linksys e2000 router.
Tested with my iPhone with SSID off, it connects no problem. So the problem is not my router.
Is this limitation of EVO?

[Q] Really low speeds on wifi

When I try to use my wifi connection at home its really really slow. Sometimes it just loads part of the websites or some other it doesnt load at all and I have to refresh it several times so it loads. I also have an iphone and a laptop which dont have this problem at all. Theyre working perfectly fine with my wifi connection.
This only happens with wifi, on 3g it works fine. I havent been able to try more wifi networks to see if this only happens with mine

It also could be a WiFi issue. I was having WiFi issues with my GNex also that I thought was the phone until I started tweaking my Router settings. Some devices are more forgiving to certain routers. In addition some devices Roam to different AP's much better than others.
I have 2 WiFi AP's in my house to span covereage across 2900sqft. I found that my WiFi was just conflicting with each other causing issues with speed and connection so this is what I did.
My Modem is a TWC Wireless Modem - WiFi turned off.
Router 1 Linksys E4200 is Bridged to TWC Modem it is dual band so I have the 5ghz band set MyHomeAP in mixed mode with a 40Mhz Spread, using 36 as the Channel. The 2.4Ghz band is set to MyHomeAP-N in N only mode with a 40mhz Spread and 11 as the channel. I need a seperate SSID here because it was causing conflicts and I needed a 2.4ghz connection upstairs for my Transformer Prime Tab since it does not support 5ghz radios.
Router 2 Netgear WNR300L with DD-WRT loaded is downstairs on the other side of the house. It is a 2.4 ghz router which I have set to MyHomeAP with a 20mhz spread set to channel 1. This allows my devices that are 5ghz compatible to Roam between each AP without conflicts.
So with all that I am now getting 45 mbs WiFi when I am upstairs and connected to the Linksys and 21 mbps downstairs when I am connected to the Netgear downstairs. The Tab is getting a consistent 15mbps on each router which is acceptable for me. This is an improvement from getting 3mbps anywhere in the else regardless of the closeness to the router or the device being used. I'm now able to maximizesmy use of the WideBand service which gets about 52 mbps on a wired connection most of the time.

The GN has lots of issues with different network gear and a lot of it can't be solved by tweaking. Seems like I've heard the most success stories with netgear. I'm using ubee and trendnet and my wifi isn't great. I get between 5 and 20 mbps and its choppy with a lot of disconnects.

You always have to be careful using multiple Wireless routers in the house, because if they are not setup right you will get consistent disconnects and low speeds. Same thing was happening to me until I really digged in and configured my multiple routers correctly. Check my previous post on how I solved my router issues.

Are you getting good signal when your connected to your wifi

Just one router, the time warner ubee docsis 3.0 modem/router. The rest are trendnet APs at 1,6,11. All with same ssid and security. No interference as checked with wifi analyzer. The wifi just sucks. Not much more you can say except try different gear which shouldn't be necessary. All of my laptops etc work great.

I tried my gnex on other wifi network and it worked well. I tried it again on mine with negative results. Idk what could be wrong, all other devices i have, 2 laptops and 1 iphone work well

What's wrong is the GNs wifi doesn't play nice with all network gear as it should. Just curious, what is your router and APs?

Your basic rate is set to 1-2mbs, so don't expect more than that. Change it to 54mbs or whatever the max is and see if it helps.

Authentication Error

Is anyone getting an authentication error displayed on access points? I get this random on my work/home access point and yes I am close to the access point. I dont think it started doing this until the 4.1.2 update.

Did you try "forget" on your connections and then recreate them?

I would love to help you, but help yourself first: ask a better question
http://www.catb.org/~esr/faqs/smart-questions.html

Yup, I deleted all and its fixed for a few hours. If I turn wifi off and back on it fix's it for a little while. Its random, but it looks like the S3 and the Note 2 have the issue. I googled it and found other people with the same issues.

Very odd. I'm assuming you're running stock and not a bleeding edge custom rom. Is this any ap, or just one or 2? Ones you control?
I really don't know enough about the spectrums and noise congestion, but if they're ones you can control, use a wifi app that'll show you all the aps and channels in your area. That should help you find a less congested one.
Until someone more knowledgeable chimes in, all I have are ideas. :/

Same problem
Yea this is really weird. I have a ASUS RT-N66U router with a 2.4 ghz band and a 5ghz band as well as a second router being used as an access point. I have a fairly large house and my first router didn't quite reach some spots. So at first I had the SSID the same for both routers. I was having problems with the setup so I changed the SSID of the access point router and all was well for a couple of weeks. then all of the sudden the RT-N66U router started giving me the Authentication error. So I have tried everything including giving the 5ghz band a diffrent SSID and that worked for the 5ght band. I can access the 5ghz band but still get the authentication error with the 2.4ghz band.

Getting this problem too.

I have the identical problem as well with the same router and the same phone.

I got this error as well on my RT-N66U and S3. So, is this a Samsung and ASUS issue?
I haven't seen this issue with other phones connecting to my N66U.

I've had this issue as well. Although I am using a belkin router.
I tried the forget this network and still had the issue come up occasionally. I reset my modem and router and haven't had the problem since.

using 2 routers in the same house is always asking for connection troubles, even if you have one of them set as "access points"; I have a netgear router, and a netgear access point in my large house, and they work just fine; I have set up the access point with a different network name than the actual router, and, when I am in the part of my house, or outside, which is closer to the access point location, I just switch wifi networks on my phone/tablet to the "other" network, and it connects just fine....

Ive gotten it randomly also...

Wow...same router (RT-N66U), same phone, same problem...!
Although for me it only happens on 5Ghz...I have the strange feeling that this will remain a mystery...!
EDIT: Got sick of this. I've scanned for other 5Ghz networks in my area in there were just 2, very low reception from where I am. Removed WPA2 and now running open with wifi mac filtering. Voila.

Got same router with note 2 and note 8 on 5 ghz. 2.4 is not an option(exceopt for poor chromecast) as it is flooded with 20 other APs. Only 1 other 5 GHz AP around on different channel with very weak signal. Note 2 is pretty good about staying conencted but somedays note 8 just will not play nice and have to switch to 2.4 GHz SSID. see new FW for outer release 9/11. Will try when i get home.

Wifi connections are driving me crazy

I've been suffering through bad wifi connections for so long I don't know if I can stand it anymore. I have my own wifi router and 2 neighbors' all set up on my phone and I spend time in all 3 houses. My phone is pretty much NEVER connected to the right access point and I can't use internet without backing out of what I'm doing and changing connections manually. There has to be a better way.
When I get home and pull in to the garage, it connects to my neighbor's router, deezmms. When I walk in to the house, it stays connected, 1 bar, but I can't do anything until I connect to my own. If I stay in the garage, it will eventually connect to the other neighbor, sparkx, again with 1 bar and a terrible connection to the internet. After connecting to my own, if I go to either neighbors I'm still stuck on my wifi, 1 bar, no internet. And it will NEVER connect to another until I'm COMPLETELY out of range of the the first.
I tried a few apps that didn't do anything at all. I've tried different settings in the advanced wifi settings that didn't help and in some cases gave me bigger problems. I had Tasker set up to turn my wifi off when I was in the car, which got me in to the house and connected to my own wifi in at least that one circumstance but raised a bunch of other headaches (losing connection to Gopro when I start the car at races, among others).
What can I do? I'm at my wits' end here.

You could set up Tasker to connect to different wifi networks according to your location, but i guess the GPS battery drainage would become a problem then. And the locations are probably too close for cellular triangulation to work properly.
An easy solution that might work: Set the wifi networks to the same wifi channel. The interference should ensure that they cancel each other out and don't creep into the next house etc. Also make sure the routers are physically so far away from each other as possible.
Just saw this app which might help. I don't have any experience with it though: https://play.google.com/store/apps/details?id=com.goramart.wifijumper&hl=da

I'll try that app.. the houses are all close enough together that GPS probably isn't going to take care of it. I might play with the channels but that sounds like it might end up causing headaches, too.
Also, I did move and upgrade my router and added some big, higher gain antennas. I really think I should be getting better range out of it than I am, but I don't know what else to try.

this seems more like a problem with the placement of your wifi router? i would check what your signals look like connected to your router througout the house. i would totally remove your neighbor's connections from your saved list so theres really no chance of connecting to their network. realistically your in house wifi should be the strongest signal lols..?

Our yards are pretty big and I spend a lot of time in all of them. I know my wifi is never going to reach to my neighbors fire pit. When I pull in to the garage their signal is stronger, and then I walk in to my house were obviously mine is stronger, but I'm stuck on the neighbors' unless I manually mess with it.
I have no idea how that Wifi Jumper app is supposed to work but it didn't do anything to help my situation. :\
