Don't be fooled by the Link Quality:0 Signal level:0 readings. In another |
| 41 |
hotel up the road I got 30/100 link quality, and got an IP address, but then |
| 42 |
I couldn't connect to the Internet. On the last hotel (with the readings |
| 43 |
quoted above) I can't for the life of me get an IP address. What am I doing |
| 44 |
wrong here? |
| 45 |

BTW this is what tcpdump reveals: |
| 47 |
========================================================= |
