View Full Version : Intermittent poor signal continued - Rebooting PC helps?

I've been battling intermittent poor performance on my SB. Typically sometime in the evening for an hour or so, my SB's performance will drop.

During the day if I run a 5000kbps test I get a constant 100%, then out of the blue in the evenings this can drop and if I try and play music I get stuttering etc.

I thought this might be down to my wireless network suffering interference, but twice last night when I was suffering from poor performance, I rebooted the PC in question and immediately ran tests again to find I then had 100% performance again.



I monitored the SB all day... Every 2hrs from 9:30am to 9:30pm I ran a 5000kbps test and got this sort of result:-
< 10 : 0 : 0%
< 20 : 0 : 0%
< 30 : 0 : 0%
< 40 : 0 : 0%
< 50 : 0 : 0%

Every test gave 100%...



Then at 10:15pm I was playing some music and noticed sluggish performance and did another test:-
< 10 : 0 : 0%
< 20 : 0 : 0%
< 30 : 0 : 0%

I connect the SB via a direct cable to the router (instead of wireless) and the test gave 100%. Returned it to wireless and the performance dropped again.

I then rebooted the PC running slimserver and immediately ran a test for 5000kbps:-
< 10 : 0 : 0%
< 20 : 0 : 0%
< 30 : 0 : 0%

How can rebooting the PC seemingly aid/solve performance (twice in a row)? Could it be SlimServer at fault here? Surely rebooting a PC wouldn't affect the routers wireless performance? Or could rebooting be giving the wireless connection a kick of some sort?

The machine in question is a Shuttle SN45G with 512meg of ram and an Athlon 3200+ processor.
