Some days ago I noticed that a lot of device pages are not accessible anymore.
The device page for TP-Link Arcer C20i e.g. now shows "This page does not exist anymore" - but if you got to "You are here" -> "Home" -> "Table of Hardware" -> "TP-Link" the device page is still there and reachable as 'TP-Link Archer C20i AC750'.
Same applies to archer-c7-1750, tp-link_archer_c59, tp-link_archer_c60_v2 and many other devices which do all appear as "This page does not exist anymore" when searched through ToH.
Sideeffect of me cleaning up the devicepages and moving them around (=renaming) during the past days. They are still there, but the dataentries need to be updated with the new links.
If you have the time and feel like doing something, you can update the links.
In many cases it's as simple as removing the additional brand name from the link, e.g.
I will change that when I have finished my current work (checking expected URLs of @mwarning vs. existing devicepages). Only 62 devices (out of 1202) left to check
