Hiya, I've got my own question this time. I currently have a Huawei B535-232 I acquired off an old 3 Broadband contract. I'm now on smarty. The router is in my loft and I get an RSSI of -63, an RSRQ of -9.0, an RSRP of -90 and a SINR OF 17 - 25. I get average speeds of 35Mbps down. This is the same as what I used to get when I had 3. I get about 25-30Mbps Upload. Would an antenna Make a difference to download speed? My closest mast is an EE & 3 mast. I wouldn't touch EE with a barge pole though because of how often they go down round here.
