I have Shaw 150 internet and receive 170 Mbps speeds when I hook my laptop directly up to the fibre modem. I have to have the modem reprovisioned to install my router (Ubiquiti USG). Once the router is installed my speeds drop to 20-30 Mbps on any device on the network. Even just having the same laptop directly wired to the router nets me a max of 21 Mbps. I have tried 2 other completely different routers with the same result. I have also replaced cables and had the USG's tech support team show me that the router is functioning correctly and is fully capable of much higher speeds.
I am lost and very frustrated especially since the internet speeds used to be as advertised and slowed down without me making any changes. Shaw says that since I am capable (with only one computer hooked directly to the modem) of obtaining the advertised speeds that this is not a problem that they can help me with.
I value and appreciate all input.
