Computer Question Regarding Wired Ethernet vs Wireless Connections

[tryfuhl]

Depending on the distance between the router and access point (wireless adapter) you should be alright. See if you can borrow a wireless adapter and move your PC downstairs to test the connection; you can also try with a laptop instead but they aren't always able to pick up/transmit as well.

What router do you have now? Most 802.11G routers will typically cover that area, if not you can always go with an 802.11N router and adapter and that should cover it no problem.

I'll assume that you have the 15mb down/1mb up package, which is in megaBITS, as opposed to megaBYTES. There are 8 bits in a byte, so your actual down speed is about 1.875 megabytes max. A 802.11G will cover that with decent signal. I'd suggest upgrading the firmware on your router if you're comfortable, but it doesn't seem to be the case.

Nothing much more than to try it.
