I do found prs 950 has problem in connecting with some routers. I had problem connecting prs 950 with my wifi router originally, it kept reconnecting and failed. But I have at least 5 other machines can connect to the router without any problem. Later I changed my router, now 950 connects wifi without any problem. So you need to try which router prs 950 can connects. Now I use Buffalo whr-g54s with DD-WRT installed.
The browser is really a problem without rotating, I do hope sony can update it with firmware, it's a nice web browser but it's so sad it can't read horizontally. Currently as a workaround, maybe you can use
http://www.google.com/gwt/n as web proxy, but it will erase all css in page. For other inconveniences: each time opening index of pdf it have to start from beginning, no text noting while note with pen is not so good, and no folder for book?
In comparison it's still a good reader. But it does need update in firmware to improve c/p, the software is a core part of the system.
