At some point in the last couple of months my wifi started being unreliable. It could be something to do with moving and needing to connect to a different wifi router, or maybe it was an update. I don't know. But I had the following problems...
- Difficulty connecting in the first place. (WPA/WPA2/tkip/aes/tkip+aes - all combinations)
- Refusal to reconnect after disconnecting.
- Disconnecting many times per hour.
- Needing to restart to reconnect.
- Wifi not functioning after resume.
- Hanging on resume.
It is an Asus 1000H with an rt2860 wifi adaptor running Ubuntu 10.10.
This is how I solved all these problems, and now my wifi is absolutely rock solid, even with a 15% signal! It's never been so good.
(1 - 4 fix problems connecting, dropouts, and problems reconnecting by replacing the unreliable rt2860 driver with the Windows version running using ndiswrapper)
1. Install ndiswapper and ndisgtk using Synaptic or apt-get.
2. Blacklist all the wifi drivers in /etc/modprobe.d/. This is the end of mine...
3. Download comm_driver_gigabyte_mimobility_v.188.8.131.52.15.zip.Code:# Nev's mods. blacklist rt2x00lib blacklist rt2x00pci blacklist rt2x00usb blacklist rt2400pci blacklist rt2500pci blacklist rt2500usb blacklist rt2800lib blacklist rt2800pci blacklist rt2800usb blacklist rt61pci blacklist rt73usb blacklist rt2600 blacklist rt2860 # Asus eee 1000H has an rt2860. To be loaded by ndiswrapper. blacklist b43 blacklist b43legacy blacklist ssb blacklist r8192s_usb
4. Use ndisgtk (System > Administration > Windows Wireless Drivers) to install the w2kxp driver contained within drivers/GN-WI30N_WP30N_WS30N_WS30HN_WS31N/WINXP2k.
(5 - 8 fix not connecting after resume by setting some kernel options)
5. sudo gedit /etc/default/grub
6. Edit the line with GRUB_CMDLINE_LINUX_DEFAULT and change it to:
GRUB_CMDLINE_LINUX_DEFAULT="pciehp.pciehp_force=1 pciehp.pciehp_poll=1 quiet splash"
7. sudo update-grub2
8. Restart the system.
(9 fixes the hanging on resume by unloading ndiswrapper before suspend and reloading it after resume)
9. Put the following in "/etc/pm/sleep.d/ndiswrapper" and chmod it +x.
Code:#!/bin/bash case "$1" in hibernate|suspend) sudo rmmod ndiswrapper ;; thaw|resume) sudo modprobe ndiswrapper ;; *) ;; esac exit $?
