Weak Wifi signal. Modem or Kernel issue? - Galaxy S III Q&A, Help & Troubleshooting

switched from paranoid ROM to Omega And my Wifi signal dropped 2 bars. IM in the same location as before so I don't understand the problem.
I know some would say just move the router nearer but I don't have that luxury because IM feeding off a neighbor.

S3 wifi reception very less range

Hey all.
I have a problem on sgs3.
Wifi reception in this is very less compared to my laptop. I sit In my garden and can use wifi on laptop very efficiently but there is weak signal in galaxy.. I is the range is less or wifi or there's a problem.

A laptop receiver has a lot more power to work with.

Yep, I won't expect S3 to have same wifi reception with laptop. So far I have no issues with it in S3.
My other cellphones and psp has more range than it

For me is opposite. Wifi range is superb.

Don't worry about bricking your device, from my point of view the benefits of custom roms far outweigh the risks. I've never had a problem so far! Atm I use Blackstar 2.1 with a pretty good wifi reception.

Judging by your Bio you're from Australia, in your region you are best to stick to the i9300T radios because of the frequencies in your country.
In saying that, the LH1 radio might work just fine, generally the idea with modems is what's good for me might be crap for you and vice-versa.
Basically YMMV.

UK and I lose 70% of signal .
So modem is not for all phones.
You can try the modem yourself.

Agree 100%, I get way worse signal on LH1

What would be considered a good modem for in the US?
That's one thing I haven't came across yet in the S3 i9300 threads, a threads featuring different modems? I came from the epic4g, being able to just throw one in with Odin.

[Q] Frustratingly Slow Data Issue

Hello, I was hoping if I could get some help on slow data speed issue. I'm currently in Baltimore, Maryland area on AT&T unlimited LTE plan using "pta" APN setting. I see people reporting averaging around 5~8mbps on hspa+ but I'm not able to go above 2mbps. Most of the time it's 1~1.5mbps and it's so frustrating.
I'm pretty sure I have the right settings, but I'm not sure why I get such a crappy data speed? Any ideas? Any advice will be greatly appreciated, thank you!

You CAN try switching modems.. but the most reliable thing you should do is to contact your service op for this
Sent from my GT-I9300 using xda premium
It depends, have you rooted?
I would do as above suggested by contacting you service provider.
However modem switch is quite easy. Not sure exactly what modem would work best in your area. But it cannot hurt to try and if it does not work out switch back...

Haven't rooted yet but I guess I'll give it a go.

Note 2 WIFI Issues on ALL roms

Trying to figure out why my wife's note 2 running JB v16 has one bar of WIFI sitting right next to my vzw S3 with full bars of WIFI signal.
This has been an issue on every note 2 rom I have flashed.
Does anyone have any possible Idea of what the heck is going on?
Thanks in advance.

Check your broadband. This will tell you what your radio's are set to. If you have updated roms, but never updated radios, that may be your problem.

I find my wifi signal is usually really weak compared to other devices too but I really figure it may just be a problem with a few of the N2s.

You could be right. Maybe I'll try and find another note 2 and test it I'm my house

Still no answers for this. Been reading all over other forums and it appears this is a pretty significant issue as well outside the root community.
Sounds like it may be a defect in some phones

I have no idea what the problem is, but the situation is exactly opposite in my house. S3 struggles to connect and stay connected, while Note almost always has full bars on wifi.

Lost signal

Hey guys I was messing with some modems and I think I flashed the wrong one and now I can't get signal to make phone calls. Does anyone have a link to the Verizon modems so I can get my signal back. I also tried restoring a nandroid backup but it restores with no signal. Oh yeah is the radio the same as the modem? Thanks.

Yes the radio is the same thing as a modem. Look in the Android Development section.

Right on man! I'm up and running again. Thanks a million, just wondering what's the difference with the different radios?
I flashed all 3 radios and all 3 just give me a 3g signal. Maybe its because I'm indoors, idk, I'll see what it looks like when I step outside.

They were just the radios that were included in the VZW updates, most times there is little difference.
It really depends on what area you are in and how strong your tower is, everyone experiences something different.

Yo bro, um the radios are great but all I get is a 3g signal all the time. I thought if I went outside I might see a 4g but nothing. Is there a 4g radio around where you can point me to. I tried to Google it but it just shows me the radios I already have . I'm in San Francisco and I always get 4g but now just the 3g.

They are all LTE/CDMA/EvDO radios. You should check mobile settings and make sure you have it set to either Global or LTE/CDMA/EvDO. If that doesn't work we need to know what ROM you're on to begin with.
