Question

Wired AND wireless together?

I've been fighting with my desktop's internet connection off & on for quite awhile. Although I thought I had eliminated my wireless router as the cause, it now appears to be the prime suspect. My desktop connects via wireless, but I've always kept an ethernet cable plugged in too; why not? So I unplugged my router yesterday and ran the ethernet cable from the cable modem directly to the port on the back of the computer and it's been working fine. If this continues for another day, I'll buy a new router so the household's portable devices will be connected again. So my question is, could it be a problem to have both wireless and ethernet cable connection at the same time? If so, I'll keep it wired and disable wireless in BIOS.

It depends

In reply to: Wired AND wireless together?

It depends pretty much entirely on whether both connections were active at the same time. If the physical cable was connected, but you had it disabled in Windows, it would have had no impact. Same as if you went the other way and the wireless connection was disabled but the physical cable was not. If you had both going at the same time, you could expect some troubles to occur.

Both active

In reply to: It depends

Nope, both were connected and neither disabled. It seemed like a "why not use both", but I'm not surprised to hear it would cause a problem.
So seeing as it's a desktop, I'll disable the wireless, and power up up the router again. Then if my laptops have sporadic wireless connection problems, I'll get a new router.
Thanks
