I've just finished installing gentoo, and everything went fine during ther install. My net worked fine throughout. When I boot into gentoo my card is detected and I can access the internet and my network. Then when I'm emerging a program, such as KDE, the download stops, and I seem to lose the connection. As soon as I reboot it works again, but then goes offline again a few minutes later. Here's the output when I do iwconfig after it goes offline:
eth0 IEEE 8-2.11-DS ESSID: "ACTIONTEC" Nickname:"Prism I"
Mode:Managed Frequency:2.437GHz Access Point: 00:20:E0:1E:76:DF

Link Quality:56/92 Signal level:-48 dBm Noise level:-144 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:1 Invalid misc:0 Missed Beacon:0
And ifconfig -a:
eth0 Link encap:Ethernet HWaddr 00:09:5B:40:9F:39

I think I setup everything correctly. I'm using dhcp, and I am connecting to a router. I couldn't find anything else in this forum that helps using the search.
Thanks. |

Just a guess: try watching this line:
| Code: | | Link Quality:56/92 Signal level:-48 dBm Noise level:-144 dBm |
if you see that sometimes the signal level is not much more than the noise level, your connection is weak and might fail. (NOTE: -48 > -144, so you're good here)
You could make a script that prints out the iwconfig blabla each second: | Code: | while :; do
iwconfig
sleep 1
done |
(change sleep 1 to sleep WHATEVER to wait WHATEVER seconds between the calls) |
