Mesh as an access point disconnects

I have a Hub 4 as the Cable Modem and am using a Mesh system to extend WiFi through the house. My preferred way of working is to use the Mesh system in access point mode and let the CM do the DHCP/router job. This is due to needing multiple ethernet connections and having a separate SSID for direct connection in case the Mesh system goes down.

 

As few months back, I started having problems with my TP-Link Mesh systems connection with the modem. which meant I had no internet access through the Mesh. Rebooting the primary unit connected by ethernet to the modem restored the connection. Working with TP-Link, they replaced the Mesh system under warranty but I still has the same issue. I suspected that the Mesh system which used a hybrid WiFi and Powerline backhaul might be the problem so I bought a new cheap Mesh system which worked well for a while but now I am getting dropouts again requiring a reboot of the Mesh system.

 

Am I doing something wrong here? After using three different Mesh systems, I will get loss of internet connection which suggests that it is the modem at fault here but is this a bad modem or bad setup on my part?

Hello jonbxx

 

Sorry to hear of the connection issues experienced, we appreciate the confusion and you taking the time to raise this via the forums.

 

We're limited to the advice we can offer where third party equipment is used and limited to what we can see connection wise when the hub is in modem mode. From looking though there does appear to be some power level issues with the hub that will require a tech.

 

I will send you a Private Message to get some more details from you.

 

Rob

The hub is in normal mode at present. I am using the mesh system in access point mode

Just as an update, we had and engineer round to check the signal levels and they were low. He refreshed all the connections but this needs further work at the cabinet to fix. I have had two dropouts since his visit

Lets see the connection data - do this..

In your browser’s URL box type in http://192.168.0.1 (or http://192.168.100.1 - if in modem mode) (DONT click these links) - and hit return. No need to log in - just click on the “Router Status” icon/text at bottom-middle (Hub3/4/5) or top/right (SH’s) - of the Login page.
Then… Navigate to these “data pages” and just copy/paste the normal “Formatted Text” (not images) 3 FULL sets of data onto here – 2 tables from the Downstream, 2 from the Upstream, & the Network Logs pages. Don't worry too much about the formatting it can be easily read & DON’T include personal data or MAC addresses - blank them out - if you copy/paste the data, the board software will do this for you (you may need to click the "submit" button again). If character limits are “exceeded” - just do two posts

Also, If you haven’t already, set up a free, secure and “offlsite” - “Broadband Quality Monitor” to continually monitor the state of your connection and record any true network dropouts , latency issues, packet drops, etc - it will thus allow you to differentiate between those and simple wifi dropouts. It does it 24/7/365 and it keeps a visual record of any/all of your network disconnections, useful data to have to match to the Network logs (in your Hub settings) and also in discussions with VM - note it will take a few hours to start seeing a sensible picture - post up the “link” to the “share live graph”. 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 then click OK

Mmmmm.. up power levels are a bit high and there is random dropping of the QAM's to 16/32 - thats not good - you are missing the T error table for upstream

Hi @jonbxx,

Sorry you're still having issues following the technician visit. 

How did the tech leave things with you?

I can see there is still a power level issue so will pop you a PM 📩 to assist further.
