Is anyone else having problems with ridiculously slow download speeds on these units? While my sprint cell phone shows 3G and full bars, my computer speed tests on this piece of shoe can't get above 0.4Mbps, but upload will run up to 1.5Mbps. Definitely not worth the money.
I've got the 250u and had 1.4Mbps down, 300kbps up on the prior version of smartview. I stupidly upgraded to 2.50.0093 and now my speeds are: 210kpbs down and 1.04Mbps up and ping times doubled. Similar problem as yours. If you have smartview 2.50 I think the problem is in the the config that came with this controller.
I'm looking for the previous version of smartview installer to get back to my prior config. I upgraded in the hopes they addressed the CPU eating issue of smartview. What idiot I was for upgrading!
