I have an ethernet cable running from my V+ box to my PC.(not wireless enabled)Also have a little modem on top of my topbox which Virgin media said I had to have...cannot imagine why,when Pc has a modem in it????????? Then I got a Netgear router from them as i have a laptop which is wireless enabled..which works great.Had to have a USB stick (Netgear) in PC.(with not being wireless).OK..all this worked fine.
Now I have a wireless PC so do not have the USB Netgear stick in it but my friend,who set it all up for me connected the ethernet cable to it...my question is...after all that...is do I need the ethernet cable in ,only there is miles and miles of it all pushed behind my desk,so would love to do away with it if it is unnecessary.
You've made it sound a lot more complicated than it probably is!
basically, if the PC is wireless and setup to connect to your wireless network then no you don't need the cable (and shouldn't have it plugged in really as it can cause problems having two separate connections to the same network)
But... if possible you'd be much better off having your desktop connected by a cable, it's faster, more secure and more reliable than wireless.
I also have a laptop which is wireless so do need to have the router which means the wireless connection automatically goes to my PC as well...so how would I run the PC by the Ethernet and laptop by router.?
