HUB 3 WIFI connection issues

[randybaton]

I'm having a bunch of weird issues.

My devices that connect by wifi keep dropping connections. They'll show me connected to the wifi network but with no internet connection. I have to forget the network and re-join entering the password. Then its fine usually for a day at least.

I have some devices connected by ethernet, these work fine but if I turn my VPN on (PIA), it will work for a few minutes and then won't connect to any sites. If I change my VPNs ports/servers it will again work for a bit and then stop. Not sure if this is related to the above or not.

I've not made any changes to my Wifi/Router/VPN for ages so i'm not sure what's happened to mess everything up.

I've reset my router a few times but it keeps happening,

Is the Hub in router mode - or in modem mode with your own router doing the heavy lifting (preferred)?

[randybaton]

Router mode.

[jbrennand]

Cant comment on any issues with VPN - except the common wisdom on here is to guarantee stable VPN connectivity you ought to be in modem mode with your own router - others may commect.

Re the wifi....
______________
If it is a wifi only issue (is it?), then on a Hub3/4/5, you could first try separating the SSID's of the 2.4 and 5 GHz wifi bands by renaming them in the settings At the same time switch off "channel optimisation/Smart wifi” and “ apply and save the settings.

All wifi devices will now need reconnecting to the best SSID at each location. Also use a wifi scanning App to find the best wifi channels to use (just select and use channels 1,6,11 on 2.4GHz) - this often helps Hub users get better wifi performance - but its still no substitute for getting better kit 🙂

To address the wifi issues, VM now supply “wifi Pods” (no longer doing cheap and cheerless “boosters”). However, their Pods are only free to customers on the 1GB, Volt (or old Ultimate Oomph) packages - is that you? If so they are worth trying - they should work for you. Its now called… Wifi Max see…….

https://www.virginmedia.com/wifi-max

You can call  0800 064 3850 to order the first one - or follow instructions on that website - or just wait here for a VM person to respond in a day or two and they will sort the first one for you . If you call dont get fobbed off by the offshore CS agents' saying you aren’t eligible it will be £5 or £8 month - you are… and it wont be - just look on the webpage.

If not free to you… you will be charged £8/month (note - BT charge £10/mo for their whole home wifi solution). It’s a simple solution and should work for you. However, you would soon pay off that cost by buying your own wireless solution that will be yours to own and use forever, although the VM Pods should be a simpler option.

You would need to get either a… (1) Mesh System, (2) Wireless router, (3) Wireless access point (4) A combination of (2,3).

£30-100 (that’s ~4->12 months of Max Pod rental) should sort it for most customers with an average property and usage.

Already have it split frequency and optimised switched off. Its not a signal strength issue, I can connect to the wifi but it won't let me access the web unless I disconnect, forget the network and re-join. My TV is about 12 inches from the router and my work laptop is about 5ft away, in the same room direct line of sight.

Hi there @randybaton 

Thank you so much for your post and welcome back to the forums! 

We are so sorry to hear that you are facing this issue with your services! I can imagine how frustrating this must be. 

Can you post your Hub status and logs? To do this;
• Please go to http://192.168.0.1 (or http://192.168.100.1 - if in modem mode),
• Don't log in, click on 'router status'
• Copy/paste the data from each of the tabs as text into a 'REPLY' as opposed to 'QUICK REPLY'. Please do not include your MAC address.
 

Also, please set up a 'Broadband Quality Monitor'. This will monitor the state of your connection and record any network dropouts etc

Give it a while to gather data and then click 'Share Live graph' and paste the 'Direct Link' into the forum. 

Thank you.

Where are you getting your equipment from? There is no.way you could.get anything for.that sort of money

[randybaton]

Wasn't my post, but I use powerline extenders to get Ethernet around my house. I have one that's a wifi booster, you can pick up refurbished ones for £30.

I switched off the wifi extender and that seems to have sorted out the issue. I think it might have been something to do with devices swapping between the extender and router. Although my tv is 10cm from my router and about 25ft from the extender so I'm not totally convinced that's why i had to keep entering the network details. I've been using the wifi extender for years and haven't updated it in ages so don't know why it would have started causing an issue. I'll leave it off for a week and see if the issues come back. If it comes back after i switch it back on i'll do a factory reset of the powerline network and extender.

Should the wifi extender be using the same channel as my router? They were on different channels, but I couldn't find anything that said thats a bad thing.
