After running into several of these cases recently, I think this may deserve a thread and possible addition to the FAQ. If a cellular-based PCMCIA wireless card is being used for internet connectivity, and the bundled connection management software is also being used (Sprint is the largest offender I've seen in the US so far) then NOD32 may detect that a proxy server is being used even when it is not. This can result in receiving "Server Connection Failure" when trying to update NOD32. This is fixed by going into the NOD32 Control Center -> Update -> Setup -> Advanced -> Setup (for Proxy server) and unchecking the "Use proxy server" option. Checking "None" as the internet connection type during installation will also circumvent this error, it seems. Has anyone else seen this, or have anything else to add?
