It seems you are using different APs with the same SSID. |
| 21 |
AFAIK, with 802.11b/g, to avoid confusing the wifi cards, neighboring AP |
| 22 |
channels should not overlap, which means they should be at least 5 |
| 23 |
channels apart (eg, 1,6,11 or 1,7,13, etc). APs transmitting on |
| 24 |
overlapping channels may cause interferences and confuse the wifi card, |
| 25 |
which might not be able to sense clearly when it is moving between APs, |
| 26 |
resulting in difficulties in deciding when to roam from one AP to |
| 27 |
another. |
