[Q]N7000 wifi problems after replacing micro usb part - Galaxy Note GT-N7000 Q&A, Help & Troubleshooting

Hi all
I bought a note 1 from friend last week and I ve got problem with it. He was replacing micro usb part because the micro usb was not working so he get it fixed. Phone shop charge him around 50 pounds dont know why, and from that time there is a problem with the phone.
Wifi is only working when you are in the same room where the router is and when you go somewhere else in the house the wifi is discconected from network. I bought new antenna cable because I thought it will help but it didnt. So I dont know now how to fix it, and also the signal is very poor after replace that part.
Can anyone help me please ?
Thanks

As far as I remember only the use of original parts from Samsung might solve this.

Okay, Thanks. I contact samsung service center and I am just waiting for them to call me back to give me a quote how much it will cost to fix the problem with signal so in other words replacing usb board for the original one.
But Does anyone had similar problems as me with wifi. I was checking wifi at my girlfriend house and it seems to work perfet I had wifi signal everywhere but when I am at my house the wifi signal is poor and its only work few metres from the router and also sometimes is working slow, but when I go somewhere in the house the wifi is disconnecting with the network.
I heard that Kernel is responsible for the wifi I changed kernel to Philz one and its same problem. I replace the antenna cable but that doesnt help me.
Any ideas what could I do about it ?
Thanks

Milestone Wi-fi/3G connects but not send data

Hello there,
As a newcomer, I found out these foruns filled up with great information and guys willing to help, so came here to ask for some help ....I am both excited and dissapointed with my brand new Milestone. Bought the handset about 5 days ago, which came with Android 2.0. Then updated it straight away to version 2.1 via "Motorola Software Update". So far so good ...here´s the problem I am facing :
While connected to wi-fi or 3g(issue is easier to notice due to 3G icon at the task bar, which points out in those small arrows data that is being sent/received) phone stops to receive data out of the blue. All connectios are cut off(it also happens when the handset is locked up). Some basic trouble shooting i did:
- tested all pcs connected to the same wi-fi network. No issues detected for these
- reset wi-fi router configs. Didn´t work
- tried other wi-fi router. Presented same issue
- swapped another carrier chip to test 3g connection. Presented the same issue
- tested my GSM chip on ther phone. Worked properly
- Reset phone to default settings. This time the connection took longer to drop, like 30 minutes, instead of the usual 10 minutes. After the first drop, it´s started behaving the same way again.​
It seems pretty much that there an issue going on here (obvious...hehehe). I am considering the following:
- Might be a software issue. So, right now i am downgrading it back to 2.0 version, check if it works properly and then move to 2.1 hopping to get the issue fixed.
- Use retailer warranty and claim for a new phone =/​
Could you guys help me out ??
Thanks in advance and Best Regards !!!
Guys, after downgrading version to 2.0, phone stills presenting the same issue. I think it´s turning into hardware issue =/....does anyone have a clue about it?
Thanks and Best Regards!!!

[Q] No WiFi networks are detected when scanning and calling does not work either

Hi all,
I have a second hand GT-n7000 in my possession.
For some reason, I am not able to detect any WiFi networks nor able to call anyone. This phone has never been rooted and is using the original rom and recovery.
If anyone has any suggestions or tips that might help me find out why the Galaxy Note is not detecting any WiFi networks, please let me know!
**UPDATE: It turns out that the rear cover is missing the top left antenna.
This is shown in this video: https://www.youtube.com/watch?v=N6CJy71_9Ok#t=191 at 3 min 11 sec.
So I'm guessing the previous owner had switched all the phone housing to make it look new.
I've tried using some random metals I've found around home to emulate the antennas, but they failed to make a difference.
If someone could remove the rear cover (which contains the antenna) and see if their phone (without the rear cover) detects any WiFi networks that would help me lots.
I really don't want to waste more money buying a phone housing that may not fix the problem.
Cheers

WIFI signal very poor. Drops out if not in 2m range.

Hey guys. I've read a lot of WiFi issues here on the forums and net but have yet to find a solution. My phone has had its WiFi range slowly reduce over time to the point where I can't go 2 meters away from the router or else it would just drop out. The problem started happening a few months back where the signal got weaker and weaker as the days went on. I was not too sure what was going on and flashed Kit Kat on it but it did not solve the issue. Went back to Marshmallow and still happening. I've tried adding a WCNSS_qcom_cfg.ini to "/system/etc/wifi" and "/system/etc/firmware/wlan" to no avail. I have also tried using legacy DHCP client in developer options. I had heard on a Sony forum that this might be hardware related and required a new motherboard. But I still don't know if it is the actual issue. If I can't find a software solution I was thinking that I can buy another Z3 Compact where the screen is broken but the actual mobo is still intact and working and replace it into my current phone.
Any advice would be greatly appreciated.
Cheers
probably u droped ur phone from hand and did some damage to it...or problem from motherboard. go to a service

Redmi 4x trouble with connection and heat

Hello fellow members. I`ve stumbled upon a trouble with my Redmi 4X. I'd like to ask you if someone had similar problems with his Xiaomi. But first thing first...
I`ve dropped my phone few days ago. Guess what - broken screen :crying:. I did some research and decided to repair it on my own. I ordered orginial replacement kit (LCD + digitizer), watched few videos "how to" and I made it. But.
It seems that now I have some problems with network. Signal strength varies between full and the lowest (on 4G), but it feels like it's always the lowest. The internet is so slow, calling and sending messages is pure luck. Sometimes you can send or call, sometimes it's like out of range. I`ve tried setting "only 3g" setting, but it doesn't help. Factory reset didn't help aswell.
Additionally, the phone is overheating. I think it may be associated with the network problem, since phone can't find himself in range of mobile operator.
I called mobile operator and they didn't do anything, everything seems to be as before.
The phone is updated to the most recent OS (Global). I don`t have any necessary or strange apps, nor root or custom rom.
Before the change of LCD everything was running smoothly.
So, did any of you guys had some similar troubles with his/hers xiaomi? Could I broke something during the replacement? I think not, I was extremely careful, assembled everything as it should be but still..
Hope you guys could figure something out, since I`m really out of my mind what is wrong now.
Thanks!

Hi, the poor reception and overheating symptoms are typical of bad antenna or its connection, which were probably damaged during the impact. Without an antenna, RF transmitter has nowhere to dissipate its energy, hence internal overheating.
Please examine the PCB-antenna pairs of contacts on both sides of the connection. Good luck...
:highfive:
Try switching between preferred network 4G/3G/2G and see if you face the same issue.
you can also try using different network carrier sim into your device and your sim cars in other device and see if this issue persist
if issue persist try reconnecting antenna cable.
