Sorry still nothing Ive tried numerous ways, but I cant get it working, but it seems like the perfect thing for my use if I can get it correct... This however works to GET MTU, but I cant figure out the correct way to SET MTU CWMIC NicConfig Where Description="Intel(R) PRO /Wireless 2200BG Network Connection - Miniport for pakkeplanlegger" GET MTU displays: MTU 1500 Can you try set your mtu with WHERE and see if you get it working?
