@David_AGL I was told to connect directly to my laptop from the modem via cable, tried and it worked well but with the erro devices, the speed I got was not the package I bought then it was identified as transmission faults from erro devices, and best to replace them. And this is what I was told "Replacement of devices will take 20 working days, first customer has to return by post and after reaching to AGL offices and they check the devices, and consider replacing..."
