Actually, I'm 25ft from an access point and the wifi signal itself is very strong. It's the throughput that sucks.
And throughput sucks REGARDLESS of the load in the CG. It's bad if there's 10 or 400 sites occupied. It's bad at noon or at 1am. It's bad if I stand underneath the access point. It's just bad...... They clearly spent a lot of money on upgrading the infrastructure. They had a 3rd party company do it (twice before they settled on the current equipment) and I don't believe Tengo did it. Can't be 100% sure tough.
After all was said and done, the money spent resulted in no better service, so in my view, it was money wasted.
