I have a dlink wireless modem and ntp protocol is being messed up or blocked. I know that the problem is in the driver not in the modem or the WAP/Router. I have used the modem under win98 with no problems setting my time from ntp servers. I have set my time under linux using my old ethernet card and cat 5 cable. But use the wireless modem under linux and I am unable to get through.
I am using gentoo-dev-sources 2.6.10 with ndiswrapper-0.12
