I didnt uninstall the old router before i installed the new one. So thats conflicting and casuing this problem?
No, that is not causing the problem.
Of course, check the router with a cable first -- Does your computer work well plugged in directly with a network cable? That way we can narrow this down to a wireless problem and not an issue with the router itself.
If it appears to be Wifi, this kind of situation can be very difficult to troubleshoot. As you can tell by searching for
WRT1600N disconnection problems, the Internet is riddled with similar issues regarding the same equipment. BUT, the if you search for *any* other router, you'll find similar results. The problem generally lies not with the hardware, rather lies within the many variables of wireless: Some routers just aren't suitable for certain locations, configurations, situations and so on.
The first thing is, in order to take advantage of the increased range and speed 802.11n offers, you need a 802.11n compatible wireless card in your computer. Do you have one? If you *do* have an 802.11n card, I would certainly expect a better connection in
most situations. It is possible that your computer is connecting via 802.11g and the Linksys router just isn't as good as your Netgear router for 802.11g in that particular location. The benefit of your Linksys is in its N technology, so make sure you're using it.
As I mentioned, I'm not convinced your Linksys router is any better than the Netgear at delivering 802.11g. It has an output power of 14dbm, which if anything, is a tad lower than your average router from Dlink or Netgear (usually 15-18dbm+). And sure, that number by itself is nearly useless (antenna sensitivity etc.. matters just as much), but I think the 14dbm is probably a good indicator that this router is not going to be any sort of improvement.. at least not without using its 802.11n features.
Something else you should know about 802.11n is that -- by design -- it works really well in cluttered environments. If you have a situation where you're depending on clear line of sign (from one building to another, for example), I've had some pretty bad results. Using 5Ghz can decrease your range also, although it may help if you're in an area with lots of wireless interference such as an apartment complex (If 5Ghz is available).
Some things you can try are changing your wireless channels, placing your router closer to the ceiling (typically results in less obstruction), investing in a 802.11n card (if you don't have one) or outfitting your router with some more powerful antennas (probably not an option).
