Hello I manage to connect to YOTA network successfully, and then start dhcp, but after a few minutes connection is lost. It is a reproducible error. I used different dhcp clients: dhclient and dhcpcd. Only dhcpcd outputs error wmx0: carrier lost. Chip: Intel 6250 Distr - Gentoo x86 Connect to YOTA (step by step): 1) wimaxd -i wmx0 -d 2) wimaxcu ron 3) wimaxcu connect network 21 (Connection successful) 4) dhclient wmx0 5) ping works and ifconfig output: wmx0 Link encap:Ethernet HWaddr 00:1d:e1:2f:d8:55 inet addr:10.117.31.207 Mask:255.255.248.0 UP RUNNING NOARP MTU:1400 Metric:1 RX packets:2 errors:0 dropped:0 overruns:0 frame:0 TX packets:2 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:20 RX bytes:672 (672.0 B) TX bytes:664 (664.0 B) 6) but after a minute ping does not work and ifconfig output: wmx0 Link encap:Ethernet HWaddr 00:1d:e1:2f:d8:55 inet addr:10.117.31.207 Mask:255.255.248.0 UP NOARP MTU:1400 Metric:1 RX packets:2112 errors:0 dropped:0 overruns:0 frame:0 TX packets:1851 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:20 RX bytes:8592400 (8.1 MiB) TX bytes:184321 (180.0 KiB) I tried kernel 2.6.36 and 2.6.37: config: -*- Networking support ---> <M> WiMAX Wireless Broadband support ---> <*> RF switch subsystem support ---> Device Drivers ---> [*] Network device support ---> WiMAX Wireless Broadband devices ---> <M> Intel Wireless WiMAX Connection 2400 over USB <M> Intel Wireless WiMAX Connection 2400 over SDIO [*] Intel Wireless Multicom WiMAX Connection 3200 over SDIO (8) WiMAX i2400m debug level Installed apps (there were no errors during compilation): 1) wimax-1.5.1 2) wimax-tools-1.4.4 3) wpa_supplicant-0.7.3 patched 4) i2400m-fw-1.5.0 I attached logs according to the instructions in FAQ (there are some errors) I hope for your help. -------------- next part -------------- An HTML attachment was scrubbed...
