Thor H. Johansen, as per http://support.lenovo.com/us/en/products /Laptops-and- netbooks/100-series/110-15ACL?tabName=Downloads&linkTrack=Mast:SubNav:Support:Drivers%20and%20Software|Drivers%20and%20Software&beta=false an update to your computer's buggy, insecure, and outdated BIOS is available (1QCN32WW). When you update to this following https://help.ubuntu.com/community/BIOSUpdate how does this improve the situation?
For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. Also, you don't have to create a new report. It is most helpful that after the BIOS is updated, if the problem is still reproducible: 1) Please provide the output of the following terminal command (not perform an apport-collect): sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date 2) Please make a comment specifically advising on how this improves the situation. 3) Please mark this report Status Confirmed. If it's not reproducible, please mark this as Invalid.

The connection and the router are known to perform better than this with other equipment. Forcing the router into 802.11g mode does, at least at a cursory glance, seem to mitigate the halting problem, but speeds remain abysmal. If there is any kind of technically involved tests I can do to speed up the debugging of this problem, let me know. I have some experience with embedded development in C.
