The "official" rt2800 module in the kernel causes low signal, always reconnect, or broke the connection.(crap) Ages ago I compiled some ralink drivers for Linux, theese had rt2860 modules, and my wlan was awesome in speed and performance. But on newer kernels its changed.

I have installed build-essential, devscripts, cdbs, gcc, I downloaded the driver from mediatek-page, I decompressed the file, I double check the ~/os/linux/config.mk (ate, wpa_supplicant e.t.c)

I edited the 2415 the line in ~/common/cmm_wpa.c to WPA_MIX_PAIR_CIPHER.

And :

FlexibleCipher = MIX_CIPHER_NOTUSE;



I have the kernel and the headers installed, but the make or sudo make command won't work.

I use the module rt2800pci

01:00.0 Network controller [0280]: Ralink corp. RT3090 Wireless 802.11n 1T/1R PCIe [1814:3090]
    Subsystem: Micro-Star International Co., Ltd. Device [1462:6891]
    Kernel driver in use: rt2800pci

but 40cm away to router the netbook have half (or worse) signal-strenght.

Any ideas?

(newer kernels: 12.04 and up) 3.5.x-x-generic-3.11.x-x-generic

Here is "big-diagnostics" of an oldie netbook (msi-wind-u135) which have this wlan-module. wlan0 (or ra0) will be the wlan, but totally gone on fresh install, wlan1 is usb wlan.

It would be helpful to know what 'newer kernel' you have. Please edit your question to add the result of: uname -r –  chili555 Nov 29 '13 at 13:56
