It is possible...the more radios you have working on the same band the more interference and noise there is in the air. However, you typically need to have a lot more than a few sources to have issues.
How old was the card you removed? If it was ancient and was actually a wireless B it could have been slowing the access point down by forcing it to be wireless N/G/B mode and costing you some performance...though you have one of the better consumer grade routers you can get so I'd hope that this wouldn't be an issue, but I personally haven't used that router with a wireless B device around. The router might be working in 5GHz mode now too if the setting is set to auto. With the old card gone all your devices are probably 5GHz capable. The 5GHz band will typically get you a faster connection, but the signal will degrade faster so you get less range. Though it usually has no issue going through just one floor and/or a few walls.
It could also have been outside sources beyond your control. The last time you tried the PS3 your neighbors might have had more devices on the same channel as you...perhaps even devices that were trying to connect over and over to your network. The PS3 might have had a firmware update that helped its wireless connection. LOL heavy solar flares that day...you never know. Wireless can be finicky sometimes and just work slower for no apparent reason as well.Edited by Vagrant Storm - 8/29/13 at 6:29am
