my IMac hogs internet from others on network

Help! every time I connect my IMac to the network my husbands desktop PC internet slows down approx 75%. So I have to pull the old laptop with windows ;( Any ideas?
I have a IMac 21.5 late 2009 OS X Yosemite using Netgear wnr3800

Buy a new router, one with dual bands: 2.4 GHz and 5 GHz. Run your iMac on one band and your husband's PC on the other. Make sure you buy a good router, one that provides more power than your old one.

And Welcome to the Mac Forums!

yea i agree that routers a antique time for a upgrade

My Husbands PC is hardwired Ethernet, I am wireless.....

You should have mentioned that in your first post. Having one machine hooked to ethernet while another is using WiFi should not task a good router. I looked up your router at the Netgear site and found specs on the Netgear wndr 3800 which is what I think you meant? Anyway, that a fairly late model router and is already equipped as dual band. What I suggest is that you setup your iMac to use the higher band (5 GHz) to see if that doesn't load things down.
