Poor wifi signal on n5100 - Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti

So I was getting great wifi signal all 50ft away,
Until I replaced my battery by myself, it was a easy process, it took me 10mins and I was done.
I booted up my tablet and I put it to charge and when I started to use it I saw my wifi signal was very poor,
Like I'm 7ft away from the router and I'm getting 2-3 bars and when I'm in my room, about 22ft away from the router, where i used to get 2-4 bars I'm now getting 0-2 bars. Even right now I'm like 10ft away from the router and I'm getting 0-2 bars and it's pissing me off so bad.
And where is the wifi antenna located on the n5100 because the internet is no help.
I'm running CM13 rom but I never had any internet problems before.
Help me and thanks.

I would try performing a hard factory reset on your device and see if that helps.

Wifi signal strength really bad :(

I just switched over to an SX66 from an Axim X30 (624Mhz) and loving the converged life.
I've had very few, minor problems but the one that really bothers me is the signal strength of the wifi connection.
In my house, from my bedroom with the Dell, I was able to get a great signal to surf with. However, with the Siemens I don't get connected at all. :x I almost have to be within 20 ft of the router (Belkin) in order to connect and then I do connect. It's not a question of speed, only distance from the router.
Also I was in a hotel last week when I bought the Blue Angel. I had the Axim with me at the time. The Axim had a great signal and I was able to retrieve emails.... The BA did not get any signal.
I am using a sotfware called Wifi companion and use the proper WEP settings but it only connects within 20 feet.
Is this as good as it gets???
Please advise!!
Thanks in advance,
Larry
To some extent, the limited range of the SX66 is due to its design; however, 20 ft sounds a bit extreme. In my experience, the range is a bit better than that -- I've picked my neighbor's WiFi more than once, so that suggests a range of at least 50 ft.
One thing that might help is updating your ROM firmware. Customized SX66-friendly upgrades can be downloaded from http://home.comcast.net/~sx66-blueangel/.
My XDA2s will only pick up the signal from my linksys router in the main rooms of my house. If I go into the conservatory (about 20 feet away) I get nothing. My laptop will pick it up ouside some 30 meters away.
From what I've read in these forums this is about average. Something to do with the antenna position inside the device.
EDIT: Right now I'm sat in my bedroom 5 feet above my wireless router in the room below. My signal strength is 50%.
EDIT 2: I just switched the setings from 'best battery' to 'best performance' and the signal strength dropped to around 33%. Wierd.

[Q] [HELP] Erratic Signal Strength

EVO Brethren,
My signal will bounce from 4 bars to NONE and back to 2 then 4. Apparently it does so during calls too because I can't talk more than a few minutes before it'll drop. At work it'll bounce from 2 to NONE all day which just drains my battery like mad.
I'm using the latest radio and have tried reflashing it. I'm pretty sure this has always happened even on the older radio. Is Sprint service really this terrible or is there something I can do to fix this?
I can't help you with your problem, other than to say that it won't happen when you are within good service coverage.
I have the same hyperactive signal bar inside my home where I get terrible service (3 bars max when the moon is just right). The signal with jump to full bars and then drop to one or zero.
I would assume that it's the radio trying to boost your signal by cranking up the power. It probably works for a second before the phone realizes that to maintain more than 3 bars of service, the radio would require a nuclear reactor to power it, and therefore promptly lowers the power to the radio.
I have no idea, thats just my guess. When I'm in great coverage it has no problem holding bars, bad coverage - crazy dancing routine.

Dumb question about Airave

OK, Sprint was nice enough to send me one of these. I got it hooked up last week and can't seem to figure out how to stay connected to the damn thing. It's installed at my office because I'm sorta in a basement and the Sprint signal is really poor, usually about -110 dB. When the phone finally "sees" the Airave, the signal rockets up to around -60 dB, and it stays there. If I then go out, however, and return a few minutes later, I have to wait all over again for it to start working. It sometimes takes one or two hours before it finds the signal. The device is about six feet from my desk, so I know it's not a range issue.
TLDR: How do I get and stay connected to the Airave?

Weak Wifi Strength?

I really only use this phone as a tiny tablet, no service on it, so its airplane mode. wifi only, its a great device. But im having weak wifi connection, the wireless router is in a bedroom, and in my office, which is just across the living room from the bedroom with the router in it, its one bar, - 88db, etc ,sometimes no signal, i'll be trying to check email on it, an ill have to stick the phone up in the air or move it around before it picks it up again,etc. i've tested same spot with ipod touch, an its has almost full bars -40ish db, no problems.. so im thinking its the phone, has anyone else noticed it?

Yes, my phone likes that. Hope 4.2 or 4.3 will fix it.

[Q] Poor data/signal after repairing charing port.

Okay, so last night I successfully replaced the charging port on my Note 2. It wasn't malfunctioning, it was just extremely loose and was hard to keep a charging cable in.
Before putting the device back together I made sure the antenna cable and all other cables were plugged in and snug.
Since the repair , my device seems to be getting horrid data. Normally I would get LTE speeds of 20mbps+ up and about 10 down, now I'm getting 5mbps down and about .05mbps up....
The signal in the status bar goes from LTE to 3g and DC (cyanogen mod, not sure what that means).
The first night I didn't notice any problems as I was at home and connected to my home WiFi network. But when I woke up the signal was awful. I can make calls and text sometimes, in some area the signal bar has an X over and has no signal at all.
Has anyone experienced this or have an idea of what might be wrong?
Any help at all would be greatly appreciated!!!
P.s. the replacement part was specifically for my device, t889.
Okay, so this morning I downloaded and flashed the most recent modem for my phone and the signal strength seems stable, LTE download speeds are around 25 to 30mbps and my signal isnt constantly switching around. However the upload speeds are still around .01 - .05 mbps which is nothing compared to my old speeds of around 5mpbs - 7mbps.
I honestly have no idea how the hardware interacts in the phone, but would the charging port that I replaced possibly be faulty? I know the antenna cable plugs into it, and it has me thinking there is some part on it that is malfunctioning. But all this is just a guess.
I'd really appreciate any feedback.
Thank you.
