I have one of those generic routers you get with your ISP but I can tell its not doing its job properly.
Connection upstairs is slow and temperamental and streaming videos to the Chromecast (5 metres away) results in consistent buffers. I don't want to break the bank as I only live in a 50sqm unit but can anyone help me with finding a new router? Under $100?
Or am I being unrealistic?
50sqm and there's an upstairs. Must be a double storey shoebox.
You should run a few speed tests and try the chromecast in another TV(or move it downstairs). There is a chance that something is blocking the signal or streaming at a higher bandwidth(eg 4k over full HD).
You can also buy wifi extenders but the router shouldn't have any issues covering the 50sqm area.
