I have a RBI Connection with Vodafone that we have had for a few years. When originally installed it delivered around 30Mbps. Over time this dropped to less than 10Mbps.
After raising the issue with Vodafone, I ended up getting a new Modem (a Huawei B525s) and new, dual Antennas setup in a MIMO configuration.
When this new configuration was installed, I had peak speeds of over 100Mpbs, with typical speeds of 70Mbps.
This lasted for approximately a week. After which time, the maximum speed is back down to 30Mbps. When I raised it with Vodafone I was told that the higher speed was achieved when connecting to a more powerful cell tower that was further away, but less reliable and now, I was connected to a "less powerful" but more reliable, closer connection. Not sure if this is correct or not, but regardless I haven't been able to get back to the original speeds of 70Mbps.
Is there a way around this? Do I need to adjust the positioning of my antennae to pick up the faster cell tower?
During the week that it ran at 70Mbps, I have no issues at all, and I can't see why I can't get back to those speeds.
