This problem has me stumped. I have a Hawking H2WR54G Dual WAN wireless 4-port router. Periodically (pretty darned frequently, actually) we lose the ability to access the web. We are not cut off from the internet, however, because we can still get Email. I have tried to disable both the NAT and Firewall modules, to no avail. I have sent several back for service, but they have all come back with the same problem. I have even tried flashing different firmware versions. I have it connected to Comcast cable and to Verizon DSL. Currently, I have the ratio set to 50-50, although I prefer it closer to 75-25 or 2/3rds - 1/3rd. Any reasonable suggestion is appreciated.
