So we're students living in a big Victorian house this year and our connectivity in the upstairs rooms is really bad. Obviously we all do work in our rooms and there are a few of us on the top floor (its 3 floors) but it makes it difficult to do when the internet keeps falling.
I was wondering if there were any tips that we could have to improve the connectivity of the Wifi because there's a few frustrated students now!
We have been looking at new routers to have upstairs too but we've read that they don't work for this purpose?
Wireless does not propagate as well vertically as it does in the horizontal plane (Think donut), so it is not suprising that wifi coverage doesn't reach the top floor, especially considering the obstacles it needs to overcome as well (Ceilings, floors, carpets, furniture etc.).
In the first instance, you could try and optimise the wireless signal by changing the wireless channel manually. Downloading a wireless scanner like InSSIDer for Windows or WiFiAnalyser for Android would help by showing you the surrounding wireless networks, the channels they are broadcasting on, and their signal strengths, so you can select the best wireless channel.
Setting the Hub's radio setting to 300Mbps (or 40Mhz channel) is not advised on the 2.4GHz band as it takes up over half of the available spectrum, making it prone to wireless interference..
I would also check for other sources of wireless interference such as A\V streaming devices, Baby monitors, Chordless phones, Microwave ovens, Plasma TVs, Security systems, etc.
However, even with the wifi signal optimised, reaching the top floor will be a challenge for the wifi signal.
I am not sure what you have read about routers, but the best solution would be to add a wireless access point (or router in access point mode) wired back to the SH by ethernet cable. If there is no easy route to lay a cable to the top floor (e.g. via the same route as the water \ central heating pipes) then you could look at powerline adapters to connect the access point back to the hub. Or, you can get powerline adapters with built in wireless access points. Bear in mind speeds will be about 15 - 25% of the advertised speed.
However, the performance of the powerline adapters depend on the layout and condition of the house's electrical circuits. It would be wise to check on the store's return policy before buying powerline adapters if you go down this route just in case the adapters do not work.
