Since upgrading to 200meg broadband from 100meg recently my laptop, and only my laptop, wifi download speed is less than it was before. On 100meg I regularly got 80 -100 meg download and 10 meg upload. Now I only get 20 - 30 meg download although the upload has increased (as expected) to 20 meg. All my other devices are achieving near to or exceeding the 200meg downloads as anticipated. Nothing has changed accept the upgrade to 200meg. Everything connected is in the same place as before (though moving the laptop around makes no difference, even right next to the router). The network adaptor has it's latest driver. I've reset the network multiple times. Changed DNS servers multiple times. Changed wifi channels multiple times. So frustrating that it's only the laptop. Have tried everything suggested on VM help pages too. Any ideas to rectify this would be greatly appreciated.

Broadcom BCM43142 802.11 bgn Wi-Fi M.2 Adapter
Driver: 7.35.352.0 (22/11/2016)
What is the date before and now?
I have experienced a similar issue, since the end of March 2020, but it got worse and was very difficult to trace the cause I too have come to the conclusion the issue is the Broadcom Wifi card, as I have two identical laptops and they both have the same issue I suspect a Windows update caused this, but cannot find one that matches up date wise from the updates installed
However, I also had a Netflix UHD account and at the end of March 2020 this would not connect the Hub 3 It looks like two issues have been encountered, Virgin lowering the available bandwidth and the Broadcom incompatability
I have now rolled back to v6.30, and no difference I also have two further laptops Noticed one was connected at 165Mbps, so it must have a Dual Band WiFi card I am therefore wondering if the M.2 card fitted can be replaced by a newer version that includes Dual Band
Yes, some laptops can have the Wifi card replaced if it's not soldered to the motherboard. You should check the manual or open the laptop and have a look
Sadly nothing in the Toshiba manual for replacing the WiFi card, only the specification (802.11n) I have located the WiFi card, and obtained a Dual Band equivalent (Intel 802.11ac) However on fitting the laptop would not start up Swapped back to the original without any problem Further research confirms the BIOS is locked to the Broadcom
Next step is a replacement laptop Typical, get 5 years and it is upgrade time...
