cisco 831 and my miserable upload speeds
- 01-08-2007
January 8, 2007, 6:51 am

i replaced my BEFSR41 with an Cisco 831. my upload speeds since then
have dropped significantly. i was able to get close to the 384kbps with
the linksys router, but now i get a lousy range of 50-112kbps.
i'm pretty sure this has something to do with my QoS policies, but i'm
not sure where the problem lies.
my understanding was these QoS policies set a fixed bandwidth in the
event specified traffic needed bandwidth. if there is no need for the
bandwidth then any traffic can use the bandwidth. at the moment it
seems that the block of bandwidth is isolated and no other traffic can
use it.
here's my current config:
