Random Request timed out when ping router

Hi,

I just noticed this morning that the internet was unstable and slow.

So i reseted the router in hope of improvement, no luck.

Tried to set it to 10Mbps instead of 100, just to see if it made some difference, none

Changed cables, same on 3 other comps on my network so i assume it aint the NIC.

When i "Ping -t 10.0.0.138" i get:

Pinging 10.0.0.138 with 32 bytes of data:
Reply from 10.0.0.138: bytes=32 time=2ms TTL=254
Reply from 10.0.0.138: bytes=32 time=1ms TTL=254
Reply from 10.0.0.138: bytes=32 time=1ms TTL=254
Request timed out.

etc etc..

Just left it on so i got a round number for the amount off lost packets, 12% 1256 sendt.

I am clueless what else to try, Anyone that have a indea?
