Windows 7: Wired cable modem and wireless router conflict

Wired cable modem and wireless router conflict

Hi all,

I am using Windows 7 Home Premium, wireless router (Di-524) and cable modem (Motorola). My cable modem was connected to the router's WAN port and port1 of the router was connected to the network adapter on my desktop.

Lately my Internet connection speed became really slow, so I thought I'd change my setup and connect the cable modem to the desktop through USB port and keep the wired connection to the router for Homegroup and file and printer sharing.

Here is my problem: when I connect the cable modem to the USB port I get an error message that I have two conflicting connections and as a result I don't have any Internet access at all. When I unplug the network cable that connects my desktop and router, the USB connection is immediately recognized, so I have Internet access but no Homegroup and printer access (my printer is connected to the router).

Is there a way in Windows 7 to setup the wireless router as a router only (no Internet)? Other words, I am trying to achieve the following setup: use cable modem through USB port for Internet access and use wireless router only for homegroup and printer/file sharing?

Hi there, At the surface of things, you could try and set the router with a static IP address and omit DNS setting.

Slow Connection

sometimes with routers when you notice a slowdown like that a reboot of the router will usually work to clear it up

as for the usb connection from the modem I have seen a lot of modems over the years that could be connected via usb like that and you will usually end up with more trouble using that connection your better off staying with your standard ethernet connection and use your router as is

also you may try a firmware update for your router i believe that router can run DDWRT

You can run two network connections. It's tricky but it does work. One secret is as aem suggested but I'd suggest one change: Don't use the router. Use an ethernet switch instead. If you don't have one, you can still us ethe router but disable it's DCHP server and make all connections to the LAN ports only.

One thing you left out is in addition to Homegroup and printer sharing, will any other PC's be on that connection that will need internet access?

I will say this however:

File and printer sharing should not account for the internet connection getting slow. As long as there isn't any traffic destined for the internet, the router will ignore it. PC to PC traffic should never passes *through* the router. It will stay on the LAN ports. If the ethernet connection is 100Mbps, it'd be very difficult to generate enough traffic to slow down the network. I have 5 machines on my system and(3 wired and 2 wireless) and the wired connection *never* has an issue.

Now it they all want to hit the internet at the same time, all bets are off.

Your D-link Di-524 is not Windows 7 compatible, plain and simple. If it's not compatible then it won't work correctly. Your connection lag is very typical for this type of problem.

To solve your problem simply purchase a new Windows 7 compatible router.

I'll bet you dollars to doughnuts that it will fix your problem.

Look here for yourself. There is zero support for Windows 7 and your router.

If you are connecting to the router's wired LAN ports and not using wireless, the choice of OS is completely irrelevant.

However, if you're connecting to the wireless radio of the router then chev65's observations are relevant. It will depend on the wireless adapter being used.

List

there is a difference between "not supported" and "won't work". Just because the manufacturer of the product (D-Link) does not officially support Windows 7 with that product, doesn't mean that product won't work. This is especially true when the product uses a third-party chipset. D-Link may not release drivers for their product specifically for Windows 7... but there is nothing stopping the chipset manufacturer from doing so.

I respectfully disagree, these pages are sloppily compiled and often wrong.

Which part of the wifi protocols aren't compatible between Windows7 and this D-Link device? There are no drivers needed in the operating system to use the router, all it needs is a working wifi card and drivers that run that card...

That's exactly my point. The router is an external TCP/IP device and the OS on any device on it's LAN ports is irrelevant.

As for the for the wireless piece, I do think there is *some* relevance. But it will be very dependent on the wireless adapter and the router playing well together. It may well come down to a wireless router supporting current implementations of say, WPA2-PSK, or 802.1x which is separate from the low level 802.11b/g protocol. This is just an observation mind you. If you want to get down to the nitty gritty, then I would agree with you completely.
