That's what we're here for! Keep posting and above all, write the answers down!!

OK... Nothing major to report. PT came round, talked on the phone to the specialist a bit, added a second SH to run along side to test (i've set up a TBB graph on this one too to compare)... Now, he didn't do anything specifically to my SH... But it's just gone back to normal on the graph (can see slight dip right at the very end):

Very odd indeed...

qasdfdsaq · 04-12-2012, 19:06

Me too

Sephiroth · 04-12-2012, 19:27

So havve you got 2 SHs running (i.e. he split your line and connected to an engineering circuit)?

banjo · 04-12-2012, 19:29

Does this show anything I should complain about ?

We do have 2 SHs running. The PT replaced the old splitter which had 3 bits coming off it to this which has 5... Photo of it (excuse my skirting boards!

)

Spoiler:

He said he'd be back tomorrow once it's had 24 hours running both SH's together to see if one is faulty and one is OK... or if both are showing weirdness etc.

on the 2nd you powered down and up which settled the connection, may be new upstream, may be SH glitch. it then started showing signs of going back to how it was today the 4th. just saying a 24hr test may not be long enough.

Sephiroth · 04-12-2012, 20:13

So - yoou've got 2 SHs running - one with your kit on it. What's on the other SH? His or your PC?

I noticed 7.3 dB attenuation from the splitter. So your modem stats would be interesting.

If it's your kit on the 2nd SH, TBB and stats would also be interesting. Otherwise what data is being collected over the other SH?

That's relatively normal - under perfect conditions a 2-way split will give you 3dB attenuation and a 4-way split will give you 6dB. Typical connector losses are around ~0.5dB, so a minimum of 7.0 is to be expected.

It'll probably have the same loss on the upstream too.

That's why I want to see the stats. The engineer has changed the site conditions.

Ah. Well compared to the previous 3-way splitter he'll only have an additional ~3.2 dB attenuation, not the full 7.3

I'm not at home now until Thursday afternoon, by then the second SH will have probably been taken away. So I won't be able to post any stats I'm afraid, my boyfriend probably won't know where to look to show me them to post to you guys.

Both connections are looking pretty stable at the minute actually...so I'm still baffled as to what the problem is!

Mine:

Second:

Sephiroth · 05-12-2012, 11:18

Can you post the stats for both please? Are they both in the ame SH mode?

It would be interesting to see if you're both in the same frwquency range up/down.

Rashboots · 05-12-2012, 11:42

I can't post stats... I've not got remote access to the SH I don't think. Unless someone can explain how?

I'm on a train though so if I CAN access it remotely, it might be difficult.

Sephiroth · 05-12-2012, 11:43

Nah - it can wait. But you can see why it might be interestting. So far, the TBBs correspond.
