wollyka wroteTheorically you could get 4 Mbps easily. However, I have seen people with better stats than you (down Attenuation in the 30) and they refused to give them 4mbps. I think it also depends on the CO
The CO is already equipped with speeds higher than 4mbps, a friend of mine already have a 4mbps (old plans) before the upgrade, we're from the same CO. Some of them, their CO really isn't equipped with such speeds, but mostly it is due to Ogero refusing to give you your desired speed simply because they can, unless you know someone from their side.
