From: Mike Easter on 16 Dec 2006 15:00 Internet access and IDServe problem - Connectivity: Motorola SB4100 cable modem to TimeWarner infrastructure, dynamic IP - Provider: EarthLink - present IP 24.152.189.211 rDNS user-0c9hfej.cable.mindspring.com - LAN: recent AirLink AR325W wirelessG 4 port ethernet router replacing Linksys BEFSR41 wired router, died - LAN elements: 3 ethernet wired running various operating systems half Win98se, half linux mostly ubuntu, one wireless Win98se with RealTek RTL8185 wireless pci nic branded as compusa wireless G pci adapter, alternately configured to access an AirLink AP421W ethernet access point or the AR325W wireless via channel 11 or 6 resp. Problem: since replacing the linksys befsr with the airlink 325 router, the wireless W98 cannot get webpages with its browser/s, however, it can see and transact readwrite with the other computers on the network, it can ping the WAN IPs, it can resolve and ping domainnames, but it cannot 'transact' with them. Longer story: The W98se wireless could previously access the internet fine via the AirLink AP which was ethernetted to the Linksys BEFSR41. The 3rd time the linksys died, it couldn't be seen at 192.168.1.1 and so it couldn't be firmware flashed again as it had before, so I replaced it with the airlink325 which was on sale at Fry's for $20. Because there were some problems with the airlink's DNS configurability, I flash upgraded its firmware. Before I did that the routere was working and providing logs to my WallWatcher software, but after the flash it didn't provide logs anymore. So I exchanged the flashed airlink router with another with the old firmware and chose to manage my DNS 'problem' from the each computer's network configuration instead of with the router's dns config. What I was trying to do with the DNS was to use opendns instead of the DHCP derived DNS. The EL dhcp dns behaves with advertisements for names that don't resolve. So does opendns, but opendns does it differently and has several advantages rather than just ads. The linksys router could use configured opendns primary and secondary dns, whereas the airlink can store the information, but still just uses the dhcp and just shows that in its status. Currently the wireless problem computer can do everything equally well or equally poorly via the airlink ethernet access point or the airlink wireless router, namely use the LAN and ping and resolve names on the internet, but not get webpages and not get idservice from the same names it can ping. There is no software firewall. Normal computer follows: Initiating server query ...

The machine may be offline or the connection port may be stealthed. Query complete. As a result of that, I can't get webpages. I also can't telnet or IDServe transact with such as the pop or smtp server, but I can ping them by name. -- Mike Easter
