Being throttled.

Tuning in

Hi guys.

So we had M250 broadband installed on the 4th of the month. And for 7 days speeds were up around 200mbs.

Since yesterday our speeds have been at 49.8.

This is at all times of day. Every test sits at forty nine point something which would suggest we are being throtttled at 50mbs.

Has anyone else experienced this, and why would Virgin be throttling our connection?

You are not being knowingly throttled - you have an issue somewhere.

What Hub model do you have and what devices are connected on ethernet cables?

Is that speed on wifi or an ethernet cable connection?

If wifi it suggests all your connections have dropped onto the 2.4 GHz band and not the faster 5GHz band - check that first.

If ethernet then you may have a faulty cable or some software is limiting speeds - for example Dell uses "SmartByte" to do that some antiviral packages can do that too.

So test it this way...

If you think that you have a BB speed problem, then to check the speeds coming in to your Hub properly, and whether they match what you should be getting, You cannot rely on wifi tests, - only speeds "TO" the Hub and out on ethernet are usually guaranteed.
So, can you test speeds directly like this. If you expect >100Mbps then.... Connect a 1GB enabled computer/laptop (check network card is set to 1GB) , with up to date drivers, via a NEW and working Cat5e/6a ethernet cable, directly to the Hub which you have put into “modem mode” ( ).

Or go into the Hub settings and turn off/disable the wifi and also disconnect all ethernet cables from the Hub, except your one device. This ensures that NO other devices are connected
Test speeds at - or - try on 2 different browsers - as Chrome sometimes gives odd results.

If they are still low – boot your device into Windows safe+networking mode - to disable any potentially interfering software - and try again.
There are many posts on here (I have a list of ~30!) where QoS software, anti-virus, unknown/flaky software, old network card drivers, corrupted browsers, bad cables or other connected devices are limiting speeds on tests.
Report back what that gets.
