You say a recent convert from BT. To which ISP?

Are you using the new ISP's router?

Ah . SSE and yes.

That seems to be what he wants to do Andrew, to alter the router's wifi settings. But barking up the wrong tree. It has to be a problem with his laptop if it's only connecting on 2.4GHz when his other kit is getting 5GHz.

If your ISP is SSE, then your router is Technicolor.
For them, login details are as follows (unless SSE messed with it):
Login - Administrator
Password - router's serial number in capital letters

But honestly, I think your PC has got no 5 GHz WiFi.
How to check: open Device Manager (open start menu and type it into the search box).
Find Network Adapters section
Copy the name for your wireless adapter and Google it.
If it doesn't say 802.11ac, it won't have 5 GHz, so don't break your router.

I have had a similar problem with a HP laptop (Windows 10, i5 processor) where the network details in task manager indicate that it connected at any thing between 2Mb/s and 54 Mb/s depending on what it felt like. I returned it to HP under warranty to have the Broadcom adapter replaced, but not much changed,and it was not uncommon to give these indicated variations in speed when at a distance of only a couple of metres,in clear view of the router.
Other older laptops in the house,and much further away from the router indicated stable connections at 54 Mb/s.
However, carrying out speed tests when the adapter was indicating 2mB/s showed download speeds of a steady 15Mb/s (my normal speed). I can only conclude that the adapter/widows software is telling me lies and there must be a software bug!
I would mention that this is a regular event and not a 'one off''
Adapter Broadcom BCM 43142 802.11bgn

This is very common and is just down to the individual cards. As you mention the throughput generally is ok as the transmit rate increases when throughput increases.

Hi I just joined so phoned to check the log in its a new version router log in all lower case admin the pass word is admin when you log in you can change to a more secure one .

I have this box the log in is admin password admin both in lower case i phone when serial number failed hope this helps

Try updating the driver, it's easily done. In Win 10;

Right mouse click the Windows logo on the extreme bottom left of your screen,
Select Device Manager
Scroll down to "Network adapaters"
Right mouse click your wifi card and select "Update Driver Software".

When it asks if the new driver is to be obtained from your pc or the internet, tell it "internet".

You might want to create a Restore Point first, just in case. (Left mouse click over the Windows logo, start typing "Create Re....." and it will appear).
This being Windows there are probably fourteen other ways of doing the same thing.
