Why exactly 2.6, because there is already 3.8? DD-WRT, Tomato and all that I found sit on 2.6.
Habit, lack of developers?
Is there anything new for this type of system?
Too big?
I've been interested for a long time.

this is nonsense, some more use 2.4, and once I saw a completely normal piece of iron with 2.2
, what's the point of changing if all functions are performed well?

Approximately for the same reasons as deli linux sits on 2.4.
Older kernels need less resources, they are already tailored for the required equipment, nothing extremely useful has appeared in the new kernels for SOHO routers.

OpenWRT 12.09 will no longer support the 2.6 kernel, there will be a transition to 3.6.
So I think the issue is being resolved slowly about the transition to new cores, just not everything is so fast.

Here they tell me on Twitter about dd-wrt - ftp.dd-wrt.com/others/eko/BrainSlayer-V24-preSP2/2013/02-11-2013-r20675/

I just recently updated open-wrt on my router. Was 10.03 with kernel 2.6, became 12.09 with kernel 3.3. I didn't notice any difference in terms of performance.

Maybe because in some routers more than 2 meters you can stick a flash with a soldering iron and not everyone will go for it. According to my acquaintances, I still have a bunch of Asus 520gc class routers, 2 meters for firmware with a head is enough, for many years it has been plowing like clockwork.
