Just went through a few days of calls with Linksys tech support. Figured out that although gateway (192.168.1.1) can be pinged, sometimes DNS cannot (126.96.36.199). Then internet is choppy and not usable. After unchecking "Block Anonymous Internet Requests" then network seems smoother. Never had this issue with the unit (WRT54GL) for the past year. Just starting showing signs of this. Running latest firmware from Linksys. Is the unit dieing? What exactly is "Block Anonymous Internet Requests"? Thanks!
