Does anyone experience wifi reception issue on Samsung galaxy s II? I am in my friend's house and the reception is very poor. Yet both my laptop & iphone 4 has no problem. Is there some setting that I can fine tune the phone?

I do get that after having the display off for a while with no network activity, it's usually solved by disabling and enabling the WiFi. I think a more permanent way of doing it is via the advanced WiFi settings and setting the WiFi to never shut down.
Just purely basing on the signal bars, on my S2 it only gives 1 bar compared to a laptop/iphone4/ipad/itouch where they get even max, but at as I increase the distance the other devices start to drop on signal bars while the S2 keeps the 1 bar, out of all the devices the S2 has the shortest range dropping off the connection while followed by the apple devices about a mere 1-2 feet more, the laptop has about a meter more of range.

Check your WiFi sleep policy under Advanced Settings.
Yes, the WiFi signal bars strength of GSII is low compared to other phones I've used, but don't know if that affects the speed or not.

plus low bar wifi signal , my download speed with wifi os very slow !! what should i do ?

do u have slow download speed tooo ??
The issue is: All the antennas are on the back bottom side of the phone (where the embossment is). When you hold it in your hand you screen all the antennas and as consequence GSM, WiFi and Bluetooth reception and transmission become poorer. Just try to hold your phone by the top side and you will be surprised with all signals quality improvement. Good luck! That's an antenna's design fault, IMHO. You may check WiFi networks strength with WiFi Analyser app.
Try also to check TX power with WiFi TX Power utility (requires iwconfig to be installed). By default samsung uses 32dBm (max). For home use 4-11dBm is enough. Probably you have 4 dBm set up and it's not enough for your conditions.

I don't even know I can adjust the transmission power. I have installed Wifi TX power utility but like what you said, it requires iwconfig. How can I install iwconfig? I am using Litening Rom with Ninphetamine-2.0.5 kernel.
Thanks.
Hi there,
Here is the zip file. Install it as zip update through CWM or CWM recovery. If first attempt is failed, just try again.

hey man! do u have any suggestion for download speed? my download speed is very slow ...
Was utilizing my home wifi signal to connect to a web site, but it would time out and not connect. Check and saw the wifi signal strength indicator with only the bottom dot illuminated. My laptop, right beside me, had all five bars illuminated. Switched the phone from wifi to data and it connected right away.
I ha e the same issue! But I am rooted. Is there any kind of a fix out there?

Same. It's weaker than the Infuse i have
The international SGS2 doesn't like D-Link routers. I don't know if the AT&T version's the same. There's less range with a D-Link for some reason and it wreaks havoc on the battery. It likes Netgear routers.
Wifi is weaker than my captivate was, but the GPS is really good. I got a solid lock in some pretty dense woods while on a hike. Whereas my captivate got awesome wifi but crap gps. I wonder if its a trade off with the antennas.
How's the signal on a 2Wire router from ATT for DSL service?
Sent from my HTC Inspire 4G using XDA app
Same issue here. My captivate had a much better reception. I checked at home and at school. Both places it had only one bar in the signal while being only 35 feet away from the router with only one wall in the way. It looses signal when further away while my laptop still has it. I'm connected on 802.11n in both places so maybe its something with that?
I also see lower wifi signals compared to iPhone 3gs.the difference isn't huge but definitely noticeable.
I noticed that too. It is weaker than my ex 3GS iPhone as well.
Weaker? Indicator?
Has there been any test on SIGNAL STRENGTH versus the number of bars? I don't mean to take a page out of ANTENNA GATE, but just having a fewer number on the display, doesn't actually indicate poorer reception.
For the guy with the 3gs, can you measure with something like speedtest.net? Since transfer speed descrease respective to signal strength, this seems like a good test.
I just bought a SGS II and would really like to know if the indicator is accurate and comparable to other devices and it does have a weaker antenna.
Thanks.
I didn't wanna make a new thread but same here. Wifi is pretty weak on this phone . Fairly disappointed at that.
To beat a dead horse, I am always at 1 or 2 wireless bars versus my IP4 being at full wifi bars. Not sure how its effecting the actual browsing though.
I will say that my GS2 consistently shows less bars than my iPad and previous iPhone 4(1 or 2 compared to full).... BUT I have yet to have a single issue browsing or accessing anything and speed is still excellent. So it could just be a display issue.
My only problem with that is that if I do really have a bad signal and have a crappy connection I'll never really know - because I'll aways asume the connection is good even though it's reporting low strength.
I've sometimes had my GS2 show extremely weak wifi signal even when sitting right next to my router - but the wifi still works just fine, inconsistently with the displayed signal strength.
So if it's showing weak but working fine, don't worry.

I can agree with this. My router is located very close to my phone and sometimes my phone shows only 1 bar of signal but the overall performance is still snappy and quick. no worries
I'm coming from a iPhone 3G. While the SGSII displays less bars it also seems to pick up wireless signals that my iPhone never detected (free wireless downtown).
Also at home in some rooms it shows less than full while my iPhone always showed full but I never noticed it being slow. I think it just displays differently.
From AnandTech
Referring to Cellular connectivity:
"In addition, Samsung makes the mistake of going with a signal bar visualization with very compressed dynamic range. Since the whole iPhone 4 debacle, I’ve seen something of a trend towards a strict linear scale (which makes more sense), but SGS2 definitely doesn’t go that route. It’s not a huge deal however, just something to be aware of. I’m willing to overlook that issue considering that getting the real story on connectivity is no harder than dialing *#0011# and looking at the real number."
Referring to Wifi:
"As with every other radio, we have to do the receive sensitivity dance and make sure nothing is broken. I tested the SGS2 alongside an SGS 4G at my house with both an Airport Extreme (5th Gen) and WRT54G-TM boosted to 184 mW. SGS2 WiFi reception on 2.4 GHz is darn near identical to the previous generation.
There’s something deceptive about this however, and it’s that although Samsung has chosen to go the usual compressed-dynamic-range route with cellular bars, the WLAN bars seem to be more linearized. Thus where I’m used to seeing every other smartphone show max (until you’re right about to fall off), the SGS2 actually doesn’t lie to me and shows fewer bars. Until I ran around and looked at RSSI in dBm, I suspected SGS2 had WLAN sensitivity issues where there don’t appear to be any. One small thing I did notice is that SGS2 (and BCM4330) seems to only connect at long guard interval (eg 65 Mbps maximum for single stream, 20 MHz channels), where SGS1 and BCM4329 connected at 72 Mbps short guard interval."
Hello guys..i bought a RAZR XT910 before about 3 weeks and i didnt notice any problems with it at all..its battery life the way i organised it with smart actions is very very good, better than my iphone 4...i have as well those black marks on the screen on low lighting and black pictures but i dont mind this either..as u can almost never see it...my problem is my weak wifi signal..i never noticed it those last 20 days as i have been working on my phone mostly on my computer desk so the phone was next to the router..the only place my phone gets 4/4 in wifi signal its when its next to the router..at 1 meter distance the signal gets 3/4 strength..at 5 meters 2/4 strength and at 10 meters the signal its lost..and this is only when im at the same room that has the router..if i go to another room the signal gets lost..especially when i close the door...i never had any wifi problem with my previous smartphones and i even had wifi outside of my house...please help me here..im quite desperate..what shall i do? return it and demand a replacement? ask for my money back? is there any way to fix this?
I don't have that problem but I'm wondering if you get it with other networks? Also have you tried resetting your router?

yea i get it with all wifi networks...for example my university, work, home..etc
Hmmm. I just ran the Speedtest app and got 12Mbps download over my wifi. It would be interesting to try that a few places and show it to VZ. Maybe they can test it on their network.

Get wifi analyzer and see if you have good signal. I notice that the Wi-Fi graphic is conservative.
my RAZR was having trouble operating on WPA2-Personal secured wifi network.. so i changed the wifi settings to WPA-Personal with TKIP and the problems are gone so you might wanna try this before you RMA.
Mine had problems with dropped and weak signal which turns out to be because I had Bluetooth on as well. If I turn bluetooth off wifi works perfectly
My WiFi reception is appalling. It only see's my home network where as my three year old HTC Hero is seeing seven!
With my package I have the ability to connect to BT Openzone hotspots around the UK.
Not much use if you can't go more than 15ft from a router without the connection dropping!
Bluetooth is off and I have tried several WiFi analysers from the market, all show a very weak signal.
Hi
On mine, yes the wifi signal (bars) are showing less then with htc desire, but I can connect without problems even the router is on the second floor and I am siting on the first, so reachable from the whole house.
I do experience, that it takes a little bit longer to find the wifi as with the desire, but once connected, works just fine.
I do not experience problems with hidden networks. Mine is not broadcasting the id, still connection is stable.

The bars on mine seem less than what the signal actually is. I connect to my home wifi just fine, from all over the house. I also connect to work's wifi from what seems like the same distance as my previous phone (Dinc)
i'm using d-link dws-125 (usb router)
when i connect and start using internet, the network disconnects in a few seconds. then it connect again and the same... etc.
please, help!!!
same problem here, hope a solution can be found as the phone is unusable in its present state
The "single ball" is enough to achieve 10mbit at my place, however, I upgraded my firmware to OpenWRT and now I get two full lines and the "ball" in the bedroom.
Stock netgear firmware is.. Incomplete. :S
Wi-fi back
Hi everybody,
I have the same problem mine is a razr from france even if i use it in italy, i found that when haveing the phone in the hand the signal gets very worst, if i hold the phone from the edges not in the hand the signal is much better i gain two signal bars, the same happens if i left the phone on the desk, the signal gest very good, as soon as i take it in the hand the signal gets bad, a kind of antenna gete from iphone....
hope this helps somebody
used to have this issue with weak wifi signals, but after installing the 85P radio update, it's gotten a bit better.
is the signal in wifi stable or is fluctuation like in arc?
what is the speed in S or is it bounded like arc to 65mbps?
one check?
WIFI connectivity is perfect with this device, no drops.
Haven't run a speed test yet.
Thanks you
Had mine for a day now and using wps setting with wifi the connection never dropped.
Is there any effect on the wifi signal strength when u hold it in landscape mode?i.e . when u have partially covered the the transparent strip in this position?
I haven't experienced any drops regardless of the position of the phone.
Don't notice any signal strength drop offs either unless I physically move away from the access point.
The 5ghz wifi signal reception is very poor - only 1 bar (out of 4) behind 1 wall, 1 meter away from router. The laptop next to the phone has 3 bars wifi reception. Is there a setting on Android (or Magisk module) to improve wifi reception? The only option I saw was wifi throttling in Developer options but it doesn't change anything.
It sounds like there is some material in the wall that is blocking the signal. It could be metal or metal containing construction material. That's not uncommon in concrete buildings or outside walls in houses. It's also possible there is some interference on the channel being used. Some options are: change the 5GHz channel on the router, switch to the 2.4MHz band, move the router (though that might cause the inverse situation) or put an access point in the next room. For best results, the access point should be wired if possible.
As mentioned, location, location, location.
Even a few feet in any direction can make a big difference. Avoid close proximity to large earth grounded objects.
Make sure the router has the lastest firmware update.
Try a network reset on your phone as well.
Thank you for your suggestions. Everything is duly noted and done physically (e.g. router location, antennas, phone without case, etc.). The only thing I need is advice of a software setting to improve wifi reception of the phone. The thing that makes me think that there is something that can be done is the 3/4 bars signal reception of my laptop as compared to the 1/4 bars of the phone.
There is probably nothing that can be done on the phone. Bars mean nothing in absolute terms. Depending on the phone and software maker, it can mean different things. Wifi is measured in milliwatts or dBm. A software wifi analyzer will usually show signal strengths in dBm. Even that can be misleading because it can depend on the hardware and software. For example, the laptop probably has larger antennas that receive a stronger signal than the phone.
What really matters is the speed of the wifi connection. Using readily available speed test software will determine the real speed of the internet connection to the device. As long as the device gets enough wifi throughput to operate well, that's all that is required.
Thank you. The 5ghz throughput is excellent, even on poor connection, but the problem is that the poor connection frequently drops and the phone does not automatically reconnect because of the poor connection. So, throughput is not a problem, poor connection is.
This may be due to a router feature called band steering or router support for mesh. They may go under other names like smart connect. What they often do is disconnect devices with a poor signal. That's fine if another usable signal is available but can result in a lost connection otherwise.
Another issue may be that auto-reconnect on the phone is disabled. It's usually enabled by default but can be changed under the advanced wifi settings for the wifi connection.
