Lately my Ubuntu WiFi is really slow. I upgraded to 11.10 but I already was experiencing slow WiFi in 11.04.
wlan0 IEEE 802.11abgn ESSID:"thename" Mode:Managed Frequency:2.412 GHz Access Point: 00:1E:E5:64:AF:75 Bit Rate=135 Mb/s Tx-Power=15 dBm Retry long limit:7 RTS thr:off Fragment thr:off Power Management:off Link Quality=70/70 Signal level=-30 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:569 Invalid misc:45 Missed beacon:0
After googling I also added the following
#disable ipv6 net.ipv6.conf.all.disable_ipv6 = 1 net.ipv6.conf.default.disable_ipv6 = 1 net.ipv6.conf.lo.disable_ipv6 = 1
to the etc/sysctl.conf file and restarted my system but it's still slow.
I found a command to show all the specs of my PC and pasted it here:
If I need to provide additional information please let me know.
