Wifi performance

I'm still on 4.0.1 and just wondered if anyone has seen any improvements on wifi with 4.0.2 or newer?
As of now i get a ping of around 10ms, 28Mb/s down and 20Mb/s up on my laptop.
On the Gnex i get response time of 40-200ms, 5-8Mb/s down and 1-1.5Mb/s up.

wow, that's terrible. have you tried it with different routers?
i didn't test my wifi performance on 4.0.1, but on 4.0.3 i'm getting 31ms, 13319kpbs down and 6899kpbs up.
one glitch i've noticed is that when i turn wifi on, or i come in range of a known wifi network with wifi on, it sometimes takes a while for the wifi to connect.

Sadly I don't have any other router to test on. I have internet through a VPN-connection and have setup a stationary computer with a wifi card as an access point so I can connect devices without the VPN-logon and such (PS3 does not support it etc.)
I ran some more tests now (speedtest.net) and now I was pretty stable at around 29-49ms, but, this is kinda strange, all test runs and servers got me ~1Mb/s down and 15-16Mb/s up. The laptop on the other hand got 56Mb/s down and 30Mb/s up.

I think I found the problem and solution.
I looked under the advanced settings in wifi and came over the "avoid bad connections" (or what it's called in english), unchecked that and the result, surprisingly, was quite different.
Any idea why this would cause this problem?

I can't find this option on my phone ?

It appears to be gone in 4.0.2. Previously, it did make quite a difference to uncheck it.

dam all hope is lost lol. Maybe they will fix it with 4.0.3.
The problem is you tube videos don't load fast enough on my nexus however on my gs2 and iPhone 4 it was instant.
Not a deal breaker but annoying ,

A phone will generally have less signal compared to a laptop because of power ability.
I also think the nexus has a weak wifi antenna compared to my transformer and my old G2x.
Download and use WiFi Analyzer to check signal and -db levels between devices. Just like the cellular signal deboggle, bars don't mean squat.

wow thats terrible! i just got my GNex saturday and it's running 4.0.2 and my wifi at home is awesome between 35-45mb download and around 15ish upload. did you ever get the 4.0.2 update message yet?

No 4.0.2 here in Norway yet. Hopefully they'll just skip the .2 and push out .3 soon.
Anyhow, looks like unchecking the 'avoid bad connections' box helped, just tested now and the speed is great

I'm on 4.0.2 GSM Google build and the wifi is still sloppy com paired to my gs2. So no the update don't fix it, and there is home screen lag now, I use a static wall paper.

Galaxy Nexus vs Nexus S

So here is the story. My Nexus S has some kind of problem preventing it from charging from a wall outlet, yet it charges from a USB cord. Anyway I have to send it in for warranty work and get it fixed. I picked up an iphone 4s since I needed a new phone, but holy crap do I hate this freaking iphone. After using ICS on my nexus s using iOS is like going from Linux to DOS.
So I am going to return the iPhone since I still can and either pick up a new Nexus S or a Galaxy Nexus. When I get my old Nexus S back I will just sell it off.
I can grab a Nexus S for 350 or a GNX for 600. Is it worth the extra 250 bucks to get the GNX?
One of the biggest things for me is battery life. With a good ICS rom and a kernal that supported deep idle my nexus S actually had pretty good life. I could go almost 2 days without charging it. Is the GNX any better or worse in this area?

If I where you I would get the galaxy nexus you like ICS on the Nexus s you'll love it even better on the galaxy nexus I can't wait for Sprint to get it I don't care if my city doesn't get 4g LTE until next year I would buy the phone now but its up to you or you can wait until next month to see what quad core phones are coming out around summer & fall

op what carrier you with ?

Rogers Wireless - Canada
Yes they are rolling out the LTE network and it is available in my area. From what I have been hearing the battery life on the LTE model is terrible. My nexus s could get around 6 hours of screen on time with wifi. From what I am hearing the GNX gets about 3.

? The CDMA version (LTE) only works with Verizon.
Everything else is GSM and supports HSPA+.

T-Mobile - horrible reception? (Time without a signal)

I've got the T-Mobile SGS3, and am getting horrible reception.. time without a signal hovers around 30% at home on this phone, where as both my Nexus One and Sensation had no problems whatsoever with signal. Going for WCDMA preferred instead of GSM auto (default out of the box setting) didn't help.. fwiw, I'm getting 3-4 bars of signal on the statusbar.
is anyone else having this issue, or is my phone just a lemon?
Thanks!

bump.. no one else is seeing bad reception?

I think a lot of people are having this problem in one way or another, including myself.

Im on sprint, and my signal is piss poor also. Take forever to logon to pandora and forget about watching any videos, impossible. I'm thinking the modern needs an update. What's the sense in having this bad ass phone if we can't even listen to internet radio in peace. I'm going back to my SSG2, and getting my HBO back for lunch

I'm still getting 25-30% time without a signal, just sitting at home.. why is the signal strength for the SGS3 so bad?! Is it a Samsung issue? I've only had HTC android phones before this one.

[q] verizon 4g lte drops connection

I have a nexus on verizon and occasionally drops my mobile connection (voice and data) when I have 4g enabled. Everything works and stays up when I only have it set for 3g. I'm using the latest radio and bootloader with BB jellybean.
Has anybody had this issue before and was able to fix it with a software update or does it usually end up with having to exchange the phone? I'm really hesitant on swapping phones because everything else works great except for this issue. I was wondering if I could fix it with re-flashing everything.

I have same problem. I purchased my phone from eBay a couple days ago and I installed BB JellyBean after activated it. I didn't really care about 4g at the time. But, now with JellyBean, I can't use 4g (full-coverage) because it drops 4g/voice within a couple of seconds and I do not have any connection. However, with 3g only, everything works great.
I don't know if I purchased faulty device or not. But, everything works fine except 4g. I read many complaints about 4g connection on Nexus. so, I may just deal with it because I can live with JellyBean and 3g data with unlimited plan.

does it happen on ICS? JB hasnt been officially released for the vzw nexus.
return to stock and see if it happens.

I'm going thru something similar...I think the radios on the vzw gnex are not the best. I've been tweeting @vzwsupport ..they told me to remove sim card wait for 30 secs put back in and check but connection still sucks. Granted, I just want 3g...no 4g in my area. Just be hearing back from them in a few.

The phone will drop to 3G to conserve battery when data is not in use. I believe there's a way to force HSPA only, you're going to have to search for it. Your phone and its radio firmware are fine though.

Currently on giffgaff and was thinking about switching to Three to take advantage of DC-HSDPA and eventually 4G, but it's worrying if the data connection is that flakey.
Sorry I can't offer any help but will be keeping a close eye on this thread and hopefully will give some insight about the Three network. The lack of 2G fallback for calls also bothers me.

I understand it will drop when not in use but this is when I'm on a website browsing it will drop and If I click a link it won't do anything it's weird

4.1.1 7105 on t-mobile does not do that, works fine.

I'm having okay data connection using the modem in your screenshot. N7105 on Three.
3G H H+ all working fine but there are some dark spots where I can't get data even with H+ on full strength.
