Question about Belkin (F5D5231-4) Router
Hello, I have a Belkin N1 Router connected on the groud floor of my bungalow. It works fine on the ground floor but I have a Desktop computer on the first floor and I use a 'N USB Wiresless adapter' to make my desktop catch the wireless signal but it does not catch any signal. I have tried to enquire everything about these routers and everyone adviced that Belkin N1 is the best among all the wireless routers and can work even on the 4-5 floors of a building. My question is that why my desktop computer or my laptop (which is not wireless) not catch any signal on the first floor. Thank you and Take care
Wireless routers all use the same frequencies either in the 2.4gHz range for 802.11b, g, or n, and 5.4gHz for 802.11a networks. These frequencies both have a VERY low penetration (it's ability to go through objects) the quarter wavelength for a 2.4gHz signal is approx. half an inch. So that means anything that size will act as an antenna and absorb some of your signal.
Chances are you floors are made of concrete and this makes almost an impenetrable barrier for wireless. Top this off with the fact that the 2.4gHz spectrum is so over saturated with noise from other devices, and the fact that there are truly on 3 NON-overlapping channels that can be used, and that 802.11n will use 2 radios on 2 non-overlapping frequencies, and you now have a pretty good idea of why this setup will no work between floors.
I used to engineer and implement wireless networks for college campuses and large offices, and even in the best of conditions we would typically set AP's on 100ft centers. Wireless networks have to wait on the slowest connection to finish with transmission before they can go on servicing other connections. So one slow connection on the edge of your coverage range could actually have every adverse affect on everyone attached to that AP.
Some food for thought. I recommed a second AP hardwared to the LAN on the second floor at the very least, and I strongly recommend staying away from 802.11n unless you know there are no other wireless LANs in the area.
