Unreliable Broadband

Connection keeps dropping and freezing which is playing havoc on two homeworkers that or on regular skype/teams/zoom meetings.

Re: Unreliable Broadband

Your Pre & Post RS Error counts are quite high.

In an ideal world they would be at zero and stay there. To zero them can you reboot the Hub using this method and then keep an eye on the counts.

Try a reboot using this method ...

Before you retire for the night can you do a 5 minute reboot on the Hub to see if the Hub can renegotiate a decent connection.

Switch the Hub off using the small switch on the rear of the Hub next to the power cord and pull the PSU plug from the wall socket.

Give it a good 5 minutes put the plug back in and switch the Hub back on.

Allow the Hub a few minutes to fully restart then check the counts again.

then

Can you set up a Broadband Quality Monitor (BQM) at thinkbroadband.com - this will give you an insight into what is happening with the signal at the other side of the Hub, it will take a few hours to get any kind of trend showing although you should post the link straight away.

Post a link to your BQM on here.

Instructions for posting BQM Link

Under your BQM graph are two links in red.

Click the lower link (Share Live Graph) then click generate.

Copy the text in the Direct Link box, beware, there may be more text than you can see.

On here click the Link icon (2 links chain to the left of the camera icon)

In the URL box paste the link you copied and in the ‘text to display’ box write My BQM then click OK - you can post the link straight away.

Re: Unreliable Broadband

Thanks Mike - I have had a monitor running for several days - tried to post images from it but left my IP Address in so the images were deleted.

I'll try to long reboot tonight

Re: Unreliable Broadband

How are you connecting to the Hub, Wi-Fi or ethernet cable ?

Re: Unreliable Broadband

Mainly on wifi but multiple decvices dropping connection.

Have tried wired (through plug socket extensions) and wasn't any better.

Re: Unreliable Broadband

What is your connection like using a direct connection using a Cat 5E/6 cable between the Hub and a 1Gbs capable Pc/Mac/Chromebook and no other devices connected ?

Re: Unreliable Broadband

Fantastic when the damn thing works but then still get random drop outs/hanging system/random disconnections.

Re: Unreliable Broadband

Can you please

Type 192.168.0.1 (192.168.100.1 in Modem mode) into your browser URL bar and press enter. 

Hub 2 & 3 When the page appears DO NOT LOG IN but click ‘Check Router Status’.

Hub 4 When the page appears LOG IN then click ‘Check Router Status’.

Copy and paste the contents of the Downstream, Upstream and Network Log tabs onto here, if you get a yellow warning click the Post button again. Use one post for each tab if you wish. Please do not use screen grabs.

A Guru will be along soon to decipher the info.
