Sudden, short drop in speed and massive increase in ping

[benwhitworth]

Hi

I am on a 8Mb/s BBand package and generally it works very well.  We have, on average, a 5-6Mbps connection speed and this goes through a BTHomeHub 2.

However... every now and again the speed crashes, it goes very slow (both on wireless and when the computer's connected directly to the HH).  When I speed test, the ping goes from approx 30ms to around 2000ms, and thespeed drops to around 0.25mbps.  If you leave it for 15 minutes it can restore itself, but it is infuriating when it happens!

I have looked through the forums and done the tests and the line seems clear.  Looking at my router does it seem to have a high SNRM??  the details are:

Mode:	ADSL_G.dmt
Traffic Type:	ATM
Status:	Up
Link Power State:	L0
	Downstream	Upstream
Line Coding(Trellis):	On	On
SNR Margin (0.1 dB):	111	250
Attenuation (0.1 dB):	150	90
Output Power (0.1 dBm):	198	119
Attainable Rate (Kbps):	10816	1128

I have checked this with two HHub2s, and it isn't the wireless and I can still use the WiFi network.  I have installed an ADSL nation faceplate, and this did help my average speed, but not the glitches.

Any thoughts?
