New HUB 3.0 terrible connection!

Hi,

After connection and speed trouble in the past week the helpdesk booked an engineer to come out and swap out the SuperHub 2 router for a new HUB 3.0. The engineer was brief and said that the power db was too high and fitted a 3db and 10db attenuators.

But nothing improved, in fact if possible it has got worse! Speed test is hit and miss sometime 20MB but most less than 10MB and more often less than 1MB with lots of disconnects. Nowhere near the 70MB advertised number.

I have now set the HUB 3.0 into modem mode and dug out my Fritz box and at least I have some stability now. But the speed issue remains. 

I have given up with the helpdesk!

Re: New HUB 3.0 terrible connection!

You likely don't need the 3db just the 10db attenuator would likely be enough.

The hub 3 has its problem and may not be fixed any time soon.

Re: New HUB 3.0 terrible connection!

Thanks for the quick reply Legacy1. I removed the 3db attenuator and power is up to 6.6dbmV with 36.6 SNR.

Do you have any details about the HUB 3.0 problem? (I'm guessing its firmware!?)

Re: New HUB 3.0 terrible connection!

Not that I said needed to remove it...so are the upstream power levers lower now?
