wi-fi trouble

Something really weird happened. My wi-fi usb stick just quit working. I mean it's working for 2 or 3 minutes then overheats and all bars disappear. Hornettek with antenna.

So i went to Fry's which is a 10 minutes drive from where i live and bought obviously the cheapest. TP LINK TL WN725N (nano) for 10 bucks. But guess what. It's not working. So i searched and read somewhere i should try wcid instead of Network-Manager which i did. Still nothing but with wcid not even Ethernet. I mean it says it connects but no it doesn't. Then i tried my bad stick with wcid and of course it does not recognize it but also it's not heating. So i'm back on Ethernet and back with questions here.

Re: wi-fi trouble

When plugging the sticks in, could you do an lsusb in a terminal, and post it here ?
a dmesg may also help I guess.

Re: wi-fi trouble

it's a realtek 8188 based adaptor which aren't great with linux since the firmware modules realtek released to kernel have a transmit power management flaw which has never been patched apart from on github for ubuntu specifically by a user of that OS. that's why it cannot find or connect to anything in fedora when you just plug it in.

Re: wi-fi trouble

From lsusb

Ralink Technology, Corp. RT2870/RT3070 Wireless Adapter is working for a minute or two (the one i used until now)

just went to Fry's, returned the TP LINK TL WN725N and bought another Hornettek. For this one lsusb says Ralink Technology, Corp. RT5372 Wireless Adapter and it's not working.

It looks like Fry's stocks everything it's not working with Fedora. Now. Cause in the past i bought two that worked and broke recently.

Re: wi-fi trouble

Ok i went to Fry's and grabbed randomly from shelf 5 wi-fi adapters. One of them was PCI rest USB. I was lucky cause the PCI one, TP -LINK TL-WN851ND was the first one i tried and worked. No questions asked from BIOS or Fedora. Four bars but only with both antennas. Now i have to return 4 unpacked usb wi-fi adapters at Fry's. One more thing. When my wi-fi broke and i went on Ethernet there was no lag while typing but earlier today i could barely type. The same thing now when i got the wi-fi on back again.
