For some reasons, the Switch tab is missing from my webfig when I remotely access the router.
On a different PC however, I can see it.
Is there a simple explanation for the missing Switch tab? Please
What versions and what routers have this problem?
Firs problem I see, you are using an ancient web browser. Use something that was released a few years back. For example IE10, Chrome, Firefox, Opera, Safari or something like that.
I am using IE version 8.0.6001.18702. Can’t be that old. 
The funny thing is I can see the Switch tab on a different PC which has the same browser version.
Anyway, your answer prompted me to use FireFox and voila.
Many thanks
Cheers
