Router Issue

[Vitaminx]

Could a router with a broken antenna be the source of lag spikes? My brothers and I get lag spikes a lot while there on xbox and I'm on computer. So I was wondering if any of you guys could suggest a good gaming router for sell on the internet. The lag usually happens randomly throughout the day. Lag spikes as in picture freezing for a set amount of time then starting back up. So if i type something in a game and i get this lag spike, the words dont appear on screen til like 20 seconds or so later. Note the lag spikes arent a set amount of time either or a set time of the day. Any good gaming router suggestions? My brothers think this is good. http://gizmodo.com/gadgets/wireless/...bgn-225619.php

If any of these are in use it can and most likely will interfere with your wireless.
