Last week I purchased a TP-Link TD-W8951ND as I was having problems with my existing D-Link DSL-2640R router with dropped connections and excessively long time for it to reconnect.
So, connection-wise so far so good, the TP-Link seems a lot more stable and either there have not been any random drops since or there have been and it's able to auto reconnect quickly.
What is not so great is the admin interface. The D-Link would very occasionally fail to respond if you tried to log into it, but the TP-Link seems to be consistently refusing to respond after about 24 to 36 hours. The internet connection itself is still up so the router hasn't actually crashed, but it just will not respond with the admin login. There's not even a page timeout either, the browser just sits there waiting for the site to load.
Have I got a dud router or has anyone else seen this problem? It's running the latest V4 firmware, release 120511, though that was not what was originally supplied. Updating it has made no difference then.
