Wireless Adapter and Dialup
Recently purchased a Linksys wpc54g to finally get my notebook on wireless.
I was looking to keep dial-up as a back-up, but ever since the installation have been having problems with the dialup. The wireless card appears to be working fine. I have tried uninstalling the wireless card still with no luck on the dial-up. Are there additional settings I need to configure to allow both to work for access or can the two not co-exist? Thanks for your help! |

Thanks for your help! Wireless and dial-up should co-exist just fine, with no need to configure anything. What type of problems are you having? If you'll give a full description, I'm sure that someone can help. -- Best Wishes, Steve Winograd, MS-MVP (Windows Networking) Please post any reply as a follow-up message in the news group for everyone to see.

The only problem with having both configured is that only one network can be active at a given time without using some obscure software for load balancing, and the like. If you establish the WLAN Internet connection first, when you dial a connection with your dial-up modem, Windows will modify the routing table to reflect the dial-up modem as the Internet gateway. If you dial the connection first, then make the WLAN Internet connection, Windows will modify the routing table to show the wireless router as the Internet gateway. Note the "Default Gateway" in each of the examples I have posted. I do not have the technical expertise to explain how to be able to use both connections simultaneously. If that is not your problem then you should describe what your problem is.

I'm going to use the general term WAN (Wide Area Network) instead of the more restrictive term WLAN (Wireless Local Area Network). You've got it exactly right, Norman, for the case shown in the route tables above, where you establish a WAN Internet connection first, and then dial a connection with your dial-up modem. Windows assigns a metric of 1 to the dial-up connection, and it adds 1 to the metric of the WAN connection. In the case that you show, that changed the metric of the ADSL connection from 1 to 2. As a result, a dial-up connection always overrides a WAN connection for Internet access. When you disconnect the dial-up connection, Windows subtracts one from the metric of the WAN connection, restoring it to its previous value. However, that's not how it works when you dial a connection with your dial-up modem first, and then make the WAN Internet connection. Windows doesn't modify the route table or change the metric of the dial-up connection when you make a WAN connection. If the WAN connection has a metric value greater than 1, Windows will still use the dial-up connection for Internet access. If the WAN connection has a metric of 1, Windows will use one or the other, and I don't know how it decides. That's the only case where it's possible for a WAN connection to override a dial-up connection as the Internet gateway. To make sure that dial-up is used even when a WAN connection is available, use the "route change" command to set the metric of the WAN connection to a value greater than 1. For example, based on the route table above, this command would set the WAN metric to a value of 2: route change 0.0.0.0 mask 0.0.0.0 192.168.102.1 metric 2 -- Best Wishes, Steve Winograd, MS-MVP (Windows Networking) Please post any reply as a follow-up message in the news group for everyone to see.

Thanks guys for the information. To be more specific, and thinking about
this some more, both the modem and wireless to be working fine. The problem comes when using the modem for internet access. When using the modem IE consistently gets DNS errrors. I've tried a few things with the registry, but not any luck. I was wondering if this is a problem with windows recognizing the appropriate internet gateway or is this an IE issue? Maybe I missed something in the set-up of the WLAN? Thanks again for your help! "N.
