Hi everyone,
I have had Virgin Media broadband for 6 months, and I am working from home by connecting via Citrix to my office virtual machine.
Everything was working fine at the beginning for four months, but in the past two months the connection to my work Virtual Machine via Citrix has been pretty awful. The connection is intermittent, in the sense that the connection is lost for 1-2 seconds every five seconds roughly, which makes working very annoying because it's like working when the connection has a strong lag.
The only thing that has changed in the past months is that we installed two smart TVs at home two months ago. So, there may be a correlation between the connection issues to Citrix and the smart TVs??
I checked with the IT department of my employer regarding the connection issue, and all is fine on their end. The issue is not the virtual machine.
Importantly, internet and the virtual machine works well when I connect to the office Virtual Machine via USB tethering from my phone instead of using the Virgin wi-fi/ broadband. And, unsurprisingly, when I tested the wifi speed in the room where my laptop is, the Virgin Media Connect app records a "great" connection.
Also, the virtual machine works well when I connect to the Hub via an Ethernet cable and browsing the internet on my personal laptop works well when using the virgin media Wifi, it's only the work Virtual Machine that doesn't work well.
Anyway, it looks that the issue is either the interface Virgin Media/ Citrix when using the wifi, or how the wifi router allocates the internet band to the various devices connected ie. the TVs and the PCs.
I did notice a drop in performance on the virtual machine when I connect via Wifi and the TVs are connected to the wifi as well. However, problems persist even when the TVs are switched off.
Additional info: I have Windows 10, and have not installed any new firewall or antivirus in the past six months.
What shall I do to improve the connection to the Virtual Machine via Citrix? And is it really not possible to have two smart TVs and laptop connected at the same time to the Virgin wifi Hub3?
Thanks for your help!

TV connections won't make any difference, and I suspect given the timing you describe that it isn't a hub fault, but an over-utilisation problem. And because of the way Citrix works (nasty, primitive throwback technology in my book) it is incredibly vulnerable to connections with poor latency.
If you want you can post the hub's status data and we can take a look for power or noise problems. Connect to the hub by clicking on this link http://192.168.0.1/ That should pull up the log in page for the hub. But don't log in, just click on the link "Check router status" That'll bring up a window with five tabs. Open the Downstream tab. Select all the text (Ctrl-A if using a keyboard), copy it (Ctrl-C), then paste it (Ctrl-V) into a reply here. Post that, do the same for the Upstream and Network log. You'll get an error message when you post the Network log, just click on "post" a second time.

Thanks!
The link http://192.168.0.1/ returns me a 404 Page not found error.
The link http://192.168.0.1 without the "/" at the end, leads me to a login page, but there is no option to "check router status", unless I log in. When I tried to login, the options and tabs are different from the one you specify.
Can you send again the link?

Dodgy syntax on my part, sorry. Are you sure that there's no small, white text that says "Check router status" from the log in page? On a Hub 3, this is below the password entry field.

This point for me means it's the WiFi, NOT the broadband, causing your issue:

yes, I also think the wi-fi is the issue, or, more specifically, the way the router allocates bandwidth/ connection. However, I am not an expert and don't know how to solve this problem.

Well it could be a faulty HUB.
Do you have a good signal strength where your device is situated, when trying to connect to Citrix over WiFi?
