Wireless speed drops over time and doesn't get up if not reconnected
- by Vili Lehto
I am using Ubuntu 12.10 64bit and I have a Asus PCE-N15 wireless card(in PCI-E slot).
The problem is that first when I connect to my WiFi network the speed is just fine, and actually my link speed never drops, it shows a solid 150mb/s+ link speed and good signal. But the download and upload speeds drop dramatically after couple minutes of use and I have to reconnect to fix this.
Network is type IEEE 802.11bgn and uses WPA2/AES encryption.
I don't have similar problems on the windows side, and the network is working fine on every other device.
iwconfig shows this:
wlan0 IEEE 802.11bgn ESSID:"WLAN-AP"
Mode:Managed Frequency:2.412 GHz Access Point: 00:1E:AB:05:EF:31
Bit Rate=300 Mb/s Tx-Power=20 dBm
Retry long limit:7 RTS thr=2347 B Fragment thr:off
Encryption key:off
Power Management:off
Link Quality=61/70 Signal level=-49 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:2 Missed beacon:0
So the question is: Is there a way to fix this?
Thanks in advance.
