I had a similar problem and complained bitterly to my ISP -- Verizon. They started an online chat and confirmed the low speed, so they ordered me a new router -- which arrived the next week.
Funny thing, though, the next DAY, my internet speeds were back to "normal". My guess is that Verizon was throttling my performance -- since I had previously been getting very good Internet speeds, and those speeds returned after I complained to them.
So, I would check with your ISP and see what they will do for you. It might not actually be a "router" problem.
