Dear friends. I have upgraded my ubuntu to the version 11.10, which uses the kernel 3.0 and just copied compiled wimax stack with libraries from previous version of Ubuntu 10.10 with kernel 2.6. I re-compiled nm0.9, so I can control the connection through it. Yes, I can connect and stay connected, but... I have Intel 6250 inbuild card. I don't know, but I experience a lot of troubles working with wimax connection. My Skype is freezing, and I am receiving the message in syslog: Connect: No buffer space available. I cannot install new network connection and only re-start of the network-manager saves. Everything seems to be okay while using wireless, Skype also freezes, but not so often. What can you suggest to do? Should I re-compile again the wimax stack? Maybe some of you faced with similar issue? Thanks in advance. With kind regards, Oleksa
