D-Link takes security very serious and and most of D-Link vulnerabilities have been fixed. D-Link does things a bit differently and each region of D-Link does there own development and support. So the Rev B is out side of the USA realm of development and support. I asked about it when If first heard that a Rev B was being released, just not in the USA since the Rev A came and and was a great success. Unfortunately both Rev A and B models are headed towards EOL in development and the only thing that would be and should be resolved is any security vulnerabilities. After that, users will need to find alternative FW if the routers support. I think the 868L HW is Broadcom based so DD-WRT and other should work well to help extend life.
Ive been using D-Link routers since 06-07 starting with the DGL-4500, another great router. Seen issues here and there however for the most part, D-Link has some great routers and do work well. I've used other Mfrs and just not impressed or they don't work well and not as good at D-Links. Trust me, I've been testing a lot since joining the forums.
Good Luck in your endeavours and enjoy the 868L for what it is. HW rocks.
