I have a wireless g router and a wireless USB dongle. I have just recently moved my pc into another room thus putting a brick wall between me and the router. I am now exxoerience drop outs and poor speeds. The router is fine on wireless devices within the room. Which makes me believe it's a range and obstruction issue.

I'm looking at some wireless n routers as they say they have better range and speed than g. My router currently has 1 antenna and the one I'm looking at appears to have 1 antenna.

Will the n router provide better connectivity and speed than my g router? Are there certain things to look for? I'm looking at a d-link router.

Not an answer to your question, but still a possible solution to your problem: Use an aluminum can as a WiFi extender. Only takes a few minutes to try it out and see if it solves your problem, before buying a new router.

I might try that. Would it also be worth considering replacing the antenna with something else. I've been looking at some at maplins and wonder if there are certain things i should look for. – David Sep 7 '12 at 20:04
You could look for an external WiFi antenna. One with a long cable would be best for this. That would allow you to place the antenna in a better location to either get around the obstruction or at least change the angle of broadcast. They also make directional antennas, which would do correctly what the tin can is attempting. Either way it would require that your current router has a removable antenna. – techturtle Sep 7 '12 at 20:35

Right now, you want to look for a router with MIMO support - these generally have 3 antennas, which they use in a synchronized fashion to significantly increase range (Note, I'm not sure if both the client an AP have to have MIMO, or if just one must have it). While wireless N does provide a bit better range over G or B, It's my understanding that in the 2.4GHz range its focus is increased throughput at the same range, rather than extended range.

You might look into routers which support the 5GHz A and N bands, presuming your devices can also operate in the 5GHz range.

I'm not very far away from the router, maybe about 15-20 feet, so I think it's just the obstructions that are causing the issue. I wonder if this will be improved with a wireless n router. – David Sep 7 '12 at 19:52
