I've just bought a Huawei B525 router to use with a mobile data SIM for home broadband. I currently have a Pixel 2 mobile phone using a Three SIM card. I get very good data speeds from my phone, get around 30 to 55 Mbps from pretty much all areas of my house. I put the exact same SIM card into the Huawei hub and the best speed I can get is 0.5Mbps. The hub is in the exact same location as my phone is when I get 30 to 55 Mbps so I don't believe it is a bad location (not outright anyway). I have tried different locations in the same room but still get the same issue. I have just ordered some external antennas (that look like this): https://images-na.ssl-images-amazon.com/images/I/41gi2gj-CHL._SY355_.jpg They have mixed reviews so I'm not very hopeful they will improve it much. Is there a better antenna that will work for this hub. I've not tried moving the hub near the window (not sure if glass will be better for signal) but I can try that location if it works. Alternatively, if there is a clearly much better antenna, then happy to try that. If I can get at least 15 to 20Mbps, then I'd be happy enough. Any suggestions?
