Intermittent wired/wireless connection

[borgy]

Hi guys I am new here with very little networking experience and I'm in desperation of help if possible please.

So basically I have a virgin media wireless router which I've put to modem mode, to which Im using an ASUS router as the WiFi signal is stronger situated in my living room.

No this is where my problem is, I've used a moca adapter to get another Asus wireless router out to my garage which I have put into AP mode.

I have then connected this AP in my garage to another ASUS router ( LAN to LAN) upstairs in my son's room and also set that one to AP mode.

My son disconnects via ethernet or WiFi every so often, let's say a couple times and hour when he's playing on his pc, even more so when I want to play call of duty with him with my Xbox in the garage on one AP router connected via ethernet and him on his AP in his room connected via ethernet.

I have no clue on settings if I'm honest, I'm completely unsure if I've set it up correctly as this intermittent drop out is making me pull my hair out now and I really need you guys help if possible please.

I look forward to hearing from some of you,

Kind regards

Louis

Are you in the UK? I assume you are as you mention Virgin Media. If that's the case I would suspect the MoCA link as MoCA isn't really a technology that's used much in the UK and the adapters are imported from abroad.

Log into your Asus router and APs and go to the System Log - General Log page on each. Look for obvious error messages related to network "links" going down around the time you're having problems.

Hi Colin. Yes im from the UK, shall I post them here if I find errors?

Yes that's fine.

It might be useful to know which MoCA adapters you're using and the length and type of cable connecting them (I don't know much about MoCA but other forum members do).

I have no clue. They were given to me just some generic black ones. And cat 5 cable also given to me on a roll. This is all I've found on the main router as of recent. But my boy has mentioned it to me several times over the last couple hours. Streaming gets interrupted also simultaneously. Bloody annoying as I have no clue. Give me a car to respray anyday

 

[ColinTaylor]

Unfortunately your screenshot is too small to read. Instead you can click on the Save button to save the file. Then either copy and paste the contents of the file or attach the entire file to you post.

Also post a photo of the MoCA adapters, somebody might recognise them. Are you sure they're MoCA? You mention Cat6 cable, but that's for Ethernet not MoCA (which is coax).

 

[borgy]

hopefully that's better Colin? The coax goes into the moca then ethernet fed from the moca to the main router. I will take a photo of the moca in a min

 

[ColinTaylor]

Well it's barely readable but it looks like your internet (WAN) connection went down. If this is the log from your main Asus router you should check the VM modem log next to see if that's causing the problem. Go to http://192.168.100.1/ and click on "Check router status" then "Network Log". Post the entire contents of that page here.

I'm sorry Colin I'm doing this on my phone trying my best here's the log from the VM Router

Your Hub log shows "RCS Partial Service" today at 14:47:10 and on 04/03/2025 at 19:40:27. So that indicates there was a problem with the Virgin Media connection. There's nothing that coincides with the Asus WAN problem yesterday at 22:07 but it may just not have been caught in the log file.

At this point I think you'll have to use your own knowledge of when you experience these problems and see if they correlate with "WAN errors" in the Asus router's log. You may have multiple problems. But you should definitely call VM and say you have a broadband problem.

You say your Asus router is in the living room. Do devices connected to that also have network problems?

What is the model number of your Asus router?

Yes my phone disconnects from time to time, and streaming buffers. Usually about 10 seconds after I hear my son get pissy because he's been "kicked" from a game lol

 

[borgy]

It certainly happens more than the virgin router log is showing. I really appreciate the time you've taken to help me hopefully others jump on board too. Means alot thankyou

Call Virgin Media and log it as a fault. I'm also with VM so I know this is absolutely the last resort but it has to be done. Good Luck. Maybe you'll get someone in the UK rather than Mumbai.

You can also try checking your service status online...

Enter your details to check your service status | Virgin Media Help

Enter your account details to check your broadband, TV or landline service status – and see if there are any issues in your area or faults with your services.

No problem. Let us know how you get on.

set the upstairs AP to a different SSID.

set the upstairs AP to a different SSID.

Both ap have their own ssid

Both ap have their own ssid

since its not a conflict its a time out error with DHCP and MOCa which they never could get DHCP to always work because the way MOCa buffers everything. What you can do is assign the wireless device a static ip outside the dhcp pool and this issue will go away.

When I use Asus device discovery both ap devices have different ip's when I access the ap IP logins it doesn't give me an option to change the way the IP is

There's nothing you've said which suggests this has anything to do with DHCP. In fact your description of the problem indicates that this isn't related to DHCP.

If you don't get anywhere with Virgin Media you should post the router's entire System Log here for us to look at.
