I installed wireless driver browsing through many posts on internet, there were compilation errors , i fixed them by tweaking the code byt after installation even though signal strength has improved but there is a kernel panic after some time ( Everything freezes) when i switch back to generic drivers, kernel panic doesnt occur please help
I have tried the same on three kernel versions 3.19,3.13,4.5 but same result
What is the “generic” driver ?
is this a 32bit or 64bit 17.3 installation ?
Is there a reason you’re not using the “generic” driver ?
What’s the output from:
lspci -vnn | grep -i net
and
sudo lshw -C network
Where did you get the drivers you compiled, and what “tweaks” did you make ?
The Generic drivers are rt2800 and rt2x00
its a 64bit installation of linux mint 17.3 Rosa
Yes there is a reason for not using Generic Drivers, They work very poorly, connection drops very frequently also there is very less wifi strength

Attached the drivers.
Tweaks Made->
2.in os/linux i ran following two commands
sed -i ‘s/__devexit/__exit/g’ pci_main_dev.c
sed -i ‘s/__devinit/__init/g’ pci_main_dev.c
in os/linux rt_linux.c i changed the TIME and DATE to a constant string value (only for kernel 4.5) no error for other kernel versions for this line
4.uninstall firmware-linux (generic)
install the deb file firmware-ralink
Commented line 1135 1136 1137 in os/linux/rt_linux.c
According to the output above it’s still loading the rt2800pci driver

oh my mistake i forgot to add rt3290 and rt3290sta in /etc/modules but after adding these two lines as soon as i start linux, again i get a kernel panic
Did you try the instructions here:
intially it gave an error in source code but then i tweaked again the source code of the file given in mentioned link now it works like a charm thanks 
Nice … well done 
And thanks for providing the extra info … it may help if the question arises again, or for people searching for a fix.
