Trying to connect my Windows 7 beta AspireOne to our wireless network (with a Netgear DG834G router), was receiving an unspecified error – “Windows failed to connect”. After playing with a multitude of settings, including security, access control, manual configuration and more, I discovered that changing wireless mode on the router from “g only” to “g & b” solved all my problems…
After that I went back and turned on all the security settings on the router again!
I’ve just had the exact same problem with my DG834Gv4 from my Windows 7 RTM laptop using an Atheros AR5007EG wireless chip.
I’m using the latest DGTeam firmware – are you?
I solved the problem by changing the wireless card in my netbook to an Intel card. That also resolved a number of other issues with the wireless in the netbook (Acer AspireOne). Can’t recall the firmware version I am using at the moment on the router…
