I have a DG834N that is sometimes blocking access to specific sites. There are 6 PCs attached, some wired, some wireless. The router has NO firewall config - it is as it came from the box. It is preventing msn messenger from communicating, it blocks access to hotmail and microsoft.com. However google works fine, along with loads of other websites. Of the 6 PCs, one wired and one wireless are affected by this. The others work fine when these two don't. If I hard reset the router, service to all PCs is restored - for a while. I have done a factory reset, but no improvement. Firmware is the latest level, although it looks like Netgear haven't issued a revision for a long time.
I have seen other posts here about similar issues, and just wondered if anyone found a cure.....
