Check that you have disabled 802.11b on your router, or you may find that an |
| 13 |
adjacent client who's running 802.11b will drag your router down to 11Mb/s max |
| 14 |
(the actual throughput will be lower). |
| 15 |
|
| 16 |
While you're experiencing the lower downloads you can run iwlist <iface> scan |
| 17 |
to see the speed at which your NIC is connecting at. If it is 802.11g it'll |
| 18 |
say so: |
| 19 |
|
| 20 |
Bit Rates:54 Mb/s |
| 21 |
Extra: Rates (Mb/s): 1 2 5.5 6 9 11 12 18 24 36 48 54 |
| 22 |
|
| 23 |
Also, iwconfig <iface> will show you IEEE 802.11g or IEEE 802.11b/g |
| 24 |
accordingly. |
