Power Levels Out Of Range? VIVID 200 Super Hub 3.0

Hi all,

 

I have been having intermittent problems with internet connection.  I think my upstream power levels have drifted out of range.  I have reset the modem and checked the connections etc.  

Can someone please confirm?

Many thanks!

Lee

Power levels are fine.

Are you experiencing problems on a wired or wireless connection?

Re: Power Levels Out Of Range? VIVID 200 Super Hub 3.0

I am using a wireless connection line of sight to a Samsung smart TV. Wireless scanner shows no wireless networks using the same channel (5GHz) . I am getting insufficient bandwidth messages from Amazon Video.

I am assuming the problem is over utilisation in my area.  Manchester M20 area.

Regards,

Lee

I wouldn't assume anything.

I would test your connection wired directly to the hub during the day and again during evening peak. 

If you are getting poor wired speed on both tests, then it looks like a technical problem.

If you are getting headline speeds during the day and poor peak time wired speeds, then it looks like an over utilisation problem.

Good wired speeds all the time would signify a wireless problem.

A direct line of sight does not negate wireless interference, as any wireless signal that is in range on the hub will be received by the hub and seen as noise on that frequency. WiFi scanners will not pick interference from domestic appliances like A|V streaming devices, baby monitors Plasma TVs, Flurorescent lighting Security cameras etc.

What sort of signal strength is your wifi scanner picking up in the vicinity of your TV?

A few speedtest.net visits using a wired connection shows 5-8Mbps download and 11.5 Mbps upload currently.  Wireless results were similar.  

RSSI -46 dBm near the TV.

That is a good wireless strength.

Looking at your wired speeds, it looks like you could be correct about the utilisation problem if daytime speeds return to normal. However, there is definetly something amiss with your local connection.

Hi evans957,

 

Thanks for taking the time to post on the community.

 

I'm sorry to read you are having issues with your broadband speeds.

 

From checking the network, there is a high peak time traffic fault in your area which is causing slow speeds. Our networks team are investigating the problem and are improving bandwidth and performance to help with this issue. The reference number is F003451999 and has a review date of 17th May.

 

Have you managed to complete speed tests during the day to see if there is a difference?

 

Let us know how you get on

Sam
