Hi Ewan, with wireless speeds you're going to have to expect to only get about half of what you get with wired, and that's a best case scenario. After that there are several environmental factors that can have a negative impact on your wireless speeds. In general you'll want to look in to Radio Frequency Interference, and try to avoid any metal, glass, or water in the area you want your wireless signal to be. If you think of wireless signal like a sound wave, any obstacles in between where the signal is coming from and where the signal is going will impede your signal somewhat. Metal, glass, water and by extension large amounts of people (since we're basically water to a wireless signal) will all damage (i.e. reflect, refract, generally fragment) the signal more than other obstructions. Also, the more wireless signal in one area, the worse your signal will be, so limiting the number of overlapping wireless signals in your network space will help with interference as well. Hope this helps!
