Yeah, I replaced the standard router because I was getting speeds like yours. The main reason I swapped was due to problems with too many devices on the internet causing it to be slow.
You can get a decent router for anywhere between £30 - £70. I'm not an expert on this stuff, so I can't say how much of an improvement it would have on yours. It depends on your house and position of your router etc. but it definitely helped mine.
Nice one. I'll try it. Any chance you could let me know your router model version or spec?
