It is quite a robust unit (metal case).

It appears to mostly do what it says on the tin (the user manual is available from their website).

I did have to reflash the firmware to the latest version when I got it.

Problems I have with it so far are:

1) It doesn't do static routes on the LAN side.
There is a nice web interface to set up "Static Routes", but it doesn't work.

I put in a support email, and they replied:
"May be you are not quite sure about the implementation of the static routing of our router. Actually, it is just ICMP redirection, it is not traditional route. When you set up static route, when the destination IP match the rule, the router will redirect the packet to the gateway according to the rule. "

2) Traceroute does not go through the TPLink properly. If I use Linux traceroute to an external address, I get no responses (all "*"). If I use Windows tracert, I get only 1 response, from the destination IP address - nothing from the hops in the middle. The only way to do a traceroute is using the web interface of the TPLink (and specifying which WAN port it should go out).

I put in a support email for this (3 times), but have received no reply.

3) There are up to 16 "Extra IP Address Dispatch Rules" - these enable you to route selected packets over one or other of the WAN ports (either prefering that port, or definitely fixed to that port). This is handy for external addresses that have firewalls which only allow incoming connections from one of your IP addresses. There is a facility to download these settings in a text file, and to upload them again. The upload facility doesn't work (it always claims an error in the file, even if it is one you have just downloaded without changing). Additionally, I find the limit of 16 rules a bit limiting (but my requirements are probably exceptional).

I put in a support email for this, and, at the third attempt I was told they would look into it, but I have heard nothing since.

I have since bought an EdiMax BR6641, which seems to work fine.
