My Router is based on Debian Etch with Linux router 2.6.18-6-686 #1 SMP Fri Dec 12 16:48:28 UTC 2008 i686 GNU/Linux and even if I install 2.6.26 it is the same effect. I am using a cell-phone "Nokia 6120 classic" and my german GSM Provider is O2/Telefonica. I get without any problems 550 kByte/Sec, but then from one second to another 2-5 kByte/Sec. I have to use 1) poff o2 2) wait for termination 3) disconnect the Nokia 4) nodprobe -r cdc_acm 5) reconenct the Nokia 6) pon o2 and now it work again... But sometimes, my Nokia (Symbian S60) crashs. Normaly I can use "cdc_ether" plus "rndis_host" but any kernel modules I have tried are crashing. (Bugreport alredy to the Debian BTS) Since the "cdc_ether" and the "rndis_host" is loaded automaticaly if I connect my Nokia I had to remove the two modules plus usbnet physicaly.
