Poor WIFI signal on sensation?

I have been using it for a couple days now. The signal is very weak on my phone, it disappears sometime. It shows "Excellent" on my laptop. Does anyone has this problem?
I'm using stock rom from tmobile.

Actually i have almost the double of wifi strength that i had on Galaxy s2, no problem at all, so test it better

Did you get the 2.3.4 update? It improves WiFi signal strength.

Mines great ! Way better than my old Evo 4g. Just picked up the NETGEAR N600 dual band wireless router. Works like a charm.

On my phone, " Upgrade version to 1.45.531.1 (45.18 MB)- FOTA update". Is this what you are talking about?

Do you know about the deathgrip issues with the Sensation? Try looking it up, it might be what's affecting your signal.

Laptops probably have better wireless antenas built in. It is after all a cellphone we are talking about. Just like your 2 core CPU is no match for a 2 core laptop/pc, same is probably true for WiFi. But that's just my guess. I don't get a lot of range on my sensation either, but my previous phones were kind of the same, maybe even weaker.

Same here !

Mine picks up the wifi from the back of the house just fine. If I turn the phone and put my hand on the top it gets worse for sure.
I dont use wifi tho so it doesn't matter at the moment. I hear the update improved this issue.

I used an iphone on the same spot. It got pretty good signal. I think that's the problem from the phone.

I don't hold the phone, just put the phone on the desk to test.

Dare i suggest try a windsurfer. I have one on a dg834g and have no wifi issues with any of my mobile devices (touch wood)

The wifi gets poor signal when you cover the top part of the back with your hand, like when you rotate it for landscape, it loses signal. Something I noticed whenever I'm on youtube

Try some of the new custom 2.3.4 ROMS. It completely fixed my deathgrip on my WifI. I don't like to name them but just look in the changelogs and you will find them,

Nope, when i am using WiFi its been good. Does this happen to you everywhere?

Question about wifi.
Hello guys, I have a question about the wifi.
I use cm10.1 and wifi on the phone is very weak (the same was with the factory-installed software)
Is there a way to strengthen the range of wifi?
Greeting.

poor signal wifi problem is here too!
if i am not wrong I think its an Hw issue cuz mine older galaxy gio gives me full range wifi and don't even drops.Sensation is dropping like hell!

There is a difference of wifi signal on CM JB roms VS ICS / Sense Roms. I tend to have a LOT better signal / performance with Sense roms.
And I'm not just talking about the signal strength bars, but speed, overal connectivity, stability, etc. Stock kicks ass, same goes to all ICS Sense roms (even ICS AOSP), but Jelly Bean roms I have signal degradation.

Any way to improve wifi reception?

Is the problem the hardware? Or can the software be tweaked? Just wanna know because as everyone knows it is horrible on this phone.

Obviously you have a crap router. I'm 30 feet from mine right now and I have full bars.

Helpful....
and really, 30 feet? that's not exactly far.....
Its not the router, it is the phone. Mine, though it will remember the networks I use, will NEVER reconnect to one when its in range. Signal strength is also an issue. All previous phones I've had have been able to get at least 2 bars of wifi signal at the other end of our house, but the Infuse just can't do it. Drops to the very least signal indicator on the display and will not pull any data.
I've had a bit better luck with Infused 1.6, but it may just be in my head as I don't think that it actually changes anything in the software for wifi over the stock ROM.
There are a LOT of posts about this and there doesn't seem to be an answer (at least that I have been able to find) to it or any work-arounds. This is really my only complaint with the phone, the wifi is absolute garbage. Some have said that its because the phone only does b/g and not N, so if you have N and you can set it to B or G that may be better.

Well from 30 feet away you should have full bars.
But at the op, I know what you mean about wifi signal. I learned though that even though it shows low bars, my speed was still good.
On the other hand, for some odd reason the miui rom made my wifi signal better. I went from about 16 mbs down to 23 down. Maybe a coincidence, I dunno.
Strychnine, try not to come across as such an ass.

Try being more successful trolls. Even laptops rarely have perfect reception through 4 walls and a ceiling at 30 feet.

I think it's mostly a hardware problem. The consensus among those who own the phone seems to be that wifi reception is average to poor.
I don't have the knowledge to be able to speak authoritatively, but I think software *can* have an impact.
With my particular Infuse, I have better reception with the new MIUI rom posted by Mikey than anything else I've tried (almost all of them). I get full reception - "excellent" - in locations where on any other rom I would have "fair" or "poor"...
I don't know if this makes sense but that is my experience.

While Strych is being rude (normal from his other posts) I have to agree that it might just be your situation.
My router is on the ground floor and I can use my wifi from the third floor in my house.
Then again I've used Wifi Analyzer (from the market) to test the channels and see what wans were overlapping mine and select one that was empty with good strength.
I also tend not to flash beta roms and then wonder why things aren't working as expected.
If you want help with your issue, you may want to post in the Q&A forum and describe what you're running, what problem you're having (specifically), and what you've done to test/fix the problem. Otherwise, if you're just ranting, I can understand that as well.

Hmm well a lot of helpful tips. I will be purchasing a brand new router. The one I have is just a basic Linksys. So ill upgrade the next level up. Idk I've never been able to get great reception. But on the flipside Ive always used a basic router.

What were you on before? AT&T Froyo or Rogers Gingerbread?
One of the problems with Rogers Gingerbread were crappy TCP buffer settings - CM7 had the "better" AT&T settings for a long time until it was updated to the new UCKI3/I4 settings. This would explain faster WiFi performance regardless of signal quality.
Signal quality has always been fine for me. Froyo has some annoying power management issues where the wifi chipset basically dies and needs to be disabled/reenabled to reconnect (This is actually common across many devices with the BCM4330 - happens a lot on the Tab 10.1 too, and in that case it's sometimes so bad that it hoses up the lockscreen.), Gingerbread seems to have fixed the wifi-death issues on our devices.

I am pretty sure this wifi problem is def not your router. I use wifi here at work and home while both receptions are TERRIBLE. I think its hardware related because I have still yet to find anyone with a fix.
thanks

I agree...both the thrill and my new phone have better reception and speeds than my infuse did.. same conditions/same router

I also have the same exact issue. I went thru 3 diff routers and no change. I also have an inspire and a iphone and they connect perfectly when mine cant. I live in a apartment and my router is in the same room. My wifes inspire works and mine dont. I know one of you are gonna say something like maybe you have too many things connected. Well that would be false. Both inspires had no problems but when i got my infuse it was just still 2 phones connected. Im calling samsung tomorrow to see what they have to say. I had alot of calls about the infuse and wifi problems also

Wifi turns off when signal is weak (1.85)

While using the phone in a spot with poor wifi reception, I've noticed the wifi icon completely goes away sometimes. It will then pop back on shortly thereafter. Is this normal behavior when it thinks the wifi signal is completely gone?

I just picked one up yesterday and have been having issues. In my bedroom it will read 2 bars, drop to one, then shut off. Comes back on within seconds. This phone seems to have WiFi issues for a lot of users.

Same problem here, but it also happens when it says i have full bars. I need to enable best wifi performance to fix it. My gsii never had this problem...

This is exactly how mine behaves too. I'm in the room with my router so I normally have full bars (and should) but every once in a while the signal goes away and comes right back 2 seconds later. I've tested it with 2 routers, a linksys running dd-wrt and a d-link one, both have the same results.

International One X has issues too. The newest update 1.85 was supposed to fix some WiFi issues along with other bug fixes, and it doesn't seem to have helped us. Let's not assume they even know what the problem is at this point.

I don't think what I am experiencing is a hardware issue at all. Im not even moving the phone when this happens, and my phone passes the squeeze test. I'm confident this means it has to be software related.
Sent from my HTC One X using xda premium

This is kind of an old/dead thread by now, but I just wanted to share my experience with wifi on the One X.
I'm also having problems, but I'm currently running a nightly (though very stable) build of CM10 on my One X and still have wifi issues. This COULD be hardware related, in that it's just crappy hardware (though it could also be software related if CM10 is built using wifi "code" (not really sure what the correct term for the wifi stuff in the software is ) from the stock software)
I'm sitting at work right now, for example, and every once in a while the wifi will disconnect. When connected it shows 2-3 wifi bars, when it's NOT connected, my wifi network shows up as "not in range" .
same type of thing has happened at my house. I thought my phone was defective so I traded it in for a replacement at best buy. Same issue. Such a shame becuase I really like everything else about this phone and wifi was never an issue on my last HTC device.

kernel changes affect wifi. some of the cm10 builds have known wifi issues.
i would never think of returning a phone because of an experience with a custom rom, since the phone wasn't built to run that rom.
always revert to full stock and see if you still have the issue. also updated ota/ruu are made to fix issues also. at&t rom doesn't have many stock wifi issues, but you can always run into issues with wifi access point incompatibilities.

Problem

:s

WiFi is not affected by radio ... you have another issue .

did some searching and i found a problem someone had that was similar with their S3. it could be a problem with the software in your phone or something. i would contact AT&T on the issue, you may need to send it in and get it fixed/get a replacement.

Hello everyone!
i have a Samsung Galaxy S2 LTE Rogers. Runing CM9.1. Using it at Claro in Ecuador. Everything runs smooth but the wifi, is not usable unless i stand nearby my router.. +10 meters away make the signal drop to one bar or disconnected. Even close to the router some times drop to 2 bars..
I tried:
Wifi Fix
FXR Wifi fix and rescue
Also install 6 different types of baseband:
Bell Note Base (celular signal stoped working)
ATT - UCLF5 Radio (came with UCLF5 leak)
ATT - UCLF6 Radio (From the Official ICS Release)
ICS RUXLF3
ROGERS - UXLF3 Radio (came with official Rogers ICS release)
ROGERS - UXKJ7 Radio (came with the official Rogers GB release)
Nothing seems to work, so I dont know what else to do, and is annoying because if i go to my room i cant get wifi or even when im at public places everyone else can get it but me.. If anyone can help me, ill really appreciate it.. Thanks in advanced..

go back to stock gb then follow the process for installing cm9 or cm10

Are you using it on 2.4Ghz band or 5? What channel? Also what kind of router? WiFi is controlled at the kernel level, your radio isn't a factor at all. Could be a hardware issue, but that doesn't seem likely. Try putting your phone outside of the router firewall through the DMZ setting. Could be a number of things. Also try downloading WiFi Analyzer from the market. It'll help in troubleshooting.

Pretty sure is using only 2.4Ghz because wifi analyzer didnt show any stars about it.. what channel, cant tell u cuz i dont know how to check it.. router is not the problem cuz is happens in all wifi connections.. can i try installing a custom kernel that boost the wifi or something like that?
when i use it really close (less than 1 meter away) to the router or in adhoc with my laptop, the up/down speed is totally fine, the problem is the wifi signal range is so weak at distance over 1 meter which then affects also up/down speed.. im desperate.. thanks for responding..

Have u checked for interference from other devices. I am haveing trouble with that. My apartment buildings router is in my hallway so anywhere near it cuts my own WiFi down. Try turning everything off except ur router especially if you have a cordless phone.

Have you tried flashing Instigator X's kernel with CM9? Sorry didn't see the part where you said it does it on public WiFi too. Flash X's kernel and if you still get bad signal, it might just be a hardware issue and it might require getting it sent in. If you're back on stock try flashing Mohan's Cymbaline kernel.

[Q] Wifi Help

Hey xda-devs. I've got a Samsung Galaxy S 4G and I'm having a bit of an issue with the wifi. First of all, this is not flashed nor rooted. At first I wasn't able to get any connection to my wifi from my room. It would show 1-2 bars of connection but a 5mb connection speed which does nothing. About a weeks after that the wifi started working in my room. This happened for about a week. Now it's doing the same thing it did the first time. Does anyone know how to fix this or get better reception on phone? Do I need to put a new modem on it?

Move your router better? Seems like maybe someone was or wasn't in the way before or somedays, wifi works better than other. but if on stock, you only get 5mb, no modem or rom is going to fix that, seems like it's a distance thing.

Well it seems like moving the router better fixes every problem. Let me elaborate some more then.
It's just this phone. One of my friends has the same model yet gets better reception than I do. This phone is a used phone and it's been dropped. I'm thinking the antenna might have gone bad from these drops.

Some router brands and isp's work better with this phone, some less. I had better connection when using att service at my friend's house than at mine on Time Warner. I believe it was the router. My original router from Linksys on g band gave full signal, while my new supposedly "state-of-the-art" router from dlink on n band only gives me 2 bars. But hey, as long as u have a connection, you are good as a full signal.

What? Since when? Signal strength is huge for how much bandwidth you can actually use out of what's available. Think of it like a water supply. The person closest to the supply gets most of what's available. The person 300 feet down the line gets less because of friction loss. Same principle just described really badly by me. LOL

Well, I was able to watch netflix on 2 bars without a hiccup. Signal strength only applicable if you have a lot of users connecting to the same router. Here is an analogy: if you only need to consume to 8 glasses of water to stay healthy, do you really need a whole tank of water?
Hit the thanks button if it helps. It's my motivator to be more helpful.

Good analogy. Try this one. Say your house is on fire. Do you want to put it out with cups or would you want that water tank close by?

Lol, that is not the same.
Hit the thanks button if it helps. It's my motivator to be more helpful.

Sure it is. Its based on how much of a resource you can use. Cups if your far away the whole tank if you're close. Why settle for cups?

Alrighty, no help so far. Here's an update on the situation. Whenever I'm like less than a foot away from my router I have full bars and the internet on my phone is running full speed. Then it disconnects for a few seconds to a minute saying I have no wifi. Anyone know how to fix this issue?

Does this happen on other wifi networks outside of your home? Or you might have hardware problem then.

I do randomly disconnect from other networks as well. So this is a hardware issue then?

We can't determine it is a hardware problem yet. Try to do a factory reset or perhaps flashing a new Gingerbread rom on this forum. Use AntonX version. Is your phone on Froyo or Gingerbread?

My friend said its a ICS problem and that all ROMs have the same problem and that flashing a kernel won't help. He also said that To get a better signal I would have to go back to froyo.....is there really no other way????
Please help and tell me how our WiFi is on your device!!

ICS displays signal strength differently from Froyo/GB. If you want an accurate view, use a ROM with percentage display rather than bars. It's still the same, it just looks different.

Yeah I read that but it's not just the bars I'm not seeing..... I'm not connecting either!!! To use my Wi-Fi I have to be exactly in the sane room as the router or the room right next to it!! And that's really limiting!!

Not sure what kind of router you are using. I would look at dd-wrt router software so you can turn up the output signal of the router. I have a netgear router that is a repeater in the house. The output on it is turned as high as possible without deteriorating the signal. And that helps the devices that have piss poor reception on the other side of the house.
