I'm running 12.2 but haven't tried any previous versions. I have a Linksys-N router, and an Asus USB-N13 wireless adapter in a mini-ATX case with an Intel DH77DF MB. As long as I'm in the same room as the router all works fine. As soon as I install the box in any other room, I can't connect to the access point (router). My wife is running an HP laptop (Windows-7) and can go anywhere in the house and get 3-4 bars on her signal quality meter. Why can't I? Attached is my dmesg output when not in the same room as the router. While in the same room as the router: # iwconfig wlan0 wlan0 IEEE 802.11bgn ESSID:"linksys" Mode:Managed Frequency:2.432 GHz Access Point: 00:18:F8:FF:72:D5 Bit Rate=18 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=68/70 Signal level=-42 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 # ifconfig wlan0 wlan0 Link encap:Ethernet HWaddr 10:BF:48:FB:C9:D1 inet addr:172.16.10.101 Bcast:172.16.10.255 Mask:255.255.255.0 inet6 addr: fe80::12bf:48ff:fefb:c9d1/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:404 errors:0 dropped:0 overruns:0 frame:0 TX packets:362 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:119068 (116.2 Kb) TX bytes:102049 (99.6 Kb) While out of the same room as the router: #iwconfig wlan0 IEEE 802.11bgn ESSID:"linksys" Mode:Managed Access Point: Not-Associated Tx-Power=20 dBm Retry long limit:7 RTS thr=2347 B Fragment thr:off Encryption key:off Power Management:off #ifconfig wlan0 wlan0 Link encap:Ethernet HWaddr 10:BF:48:FB:C9:D1 inet addr:172.16.10.101 Bcast:172.16.10.255 Mask:255.255.255.0 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) Any help appreciated.
