Disconnecting but not losing sync


[link to this post]
 
Recently ive noticed by connection disconnecting (once a day) but i still retain sync. This has only started to happen in the past week or so, but i keep sync with the exchange, but may lose a connection for 30 seconds or so until it reconnects.

What could be the problem? Im guessing it cant be the exchange as im keep sync, and all the filters etc are correctly set up

It could be a problem with renewing the PPP lease. What ISP is it, and what make/model of router have you got?

Is it a replacement router, or a firmware upgrade done?

I say it happens daily, but its not to a set time. Sometimes it can disconnect within an hour of each other, other times it may go a day or 2 without doing it.

Im on ADSL24 (Murphx). And i have a Netgear DG834Gv5 which i bought new 18 months ago, with V6.00.25 firmware

From memory, at the bottom of one of the pages there is a Connection Status button?

Is there another button to the right of the one that gave you that?

Ah well. That one is where you used to see the lease details before the v5.

I can see the lease details using the connection status icon in the System Tray.

The lease is always obtained when i turn the PC on, and expires exactly 24 hours later. Im assuming thats a different one tho seeing as the router is always on? (pc is turned off nightly)

Yes, the router gets a lease on the connection session, often 12 hours, which should automatically be renewed after 6 hours so it has a chance of another go if it fails.

Not so. IPCP does not have a concept of 'lease time' and there is no mechanism for renewing (or releasing for that matter) the address.

The only way to do either is for one end to tear down the PPP connection such that IPCP negotiation happens again.

So this thread and any earlier ones linked to from it is total garbage and imagination by all concerned?

Including the mods to Netgear firmware made by an ISP to circumnavigate the problem?

This post is particularly relevant.

Interesting...will read in depth but it appears that somehow they're ignoring IPCP and running DHCP over the established PPP session.

OK, so perhaps they're running LCP without IPCP.

I'm confused! Need to do more reading.

I accept I'm no expert on the topic, I'm sure you truly know more than me about it, but that was a real problem with the Broadcom-based 834s popular on O2.

I was merely trying to find the equivalent info from the OP's Conexant-based one to see if there was anything similar causing his problem.

Though I think it was a long shot anyway as if I've understood him correctly the times are irregular anyway, and lease expiry is regular.

Just a question do you connect anything else such as a games console to the router ?
if only use for the 1 pc, then you do not need the router DHCP to be enabled, you just give your pc a static ip, and put the DNS ip's in router, and use router ip as dns ip on your pc, i think IIRC the DG834V5 has a bug with the DHCP could be the reason for it

The threads you have referred to have absolutely no relevance to PPP. O2 doesn't use PPPo? on its LLU products. O2 uses DHCP or STATIC on the LLU products.
There is a 'lease' period associated with DHCP - please look up the appropriate RFC (I'll let you GOOGLE it for yourself).

As stated by JonRennie, there is no lease period associated with a PPP session - again, please feel free to look up the appropriate RFC.

However, some ISPs do terminate the PPP session due to lack of activity - I have no idea why they do this. I believe the practice was quite common in Deutschland.
I do not know of any UK ISPs who terminate PPP sessions after a set period of inactivity.

Whilst I have already acknlowledged to JonRennie he certainly knows more than me, I was hunting around for possibly relevant info, that's all, as already replied to him. So your stricture, although (I assume) technically correct, is unnecessary.

Relevantly, tongue, have you established the OP isn't on O2 LLU?

Aside from that, Anonymous posters should have the courage to register and become accountable for what they say to anyone. So do so!

Very iregular. Since my last disconnect (Monday 4am) not had one since.

I do seem to go through these spells. I once went 3 weeks without a disconnect, then got one every day for a week after that. Makes no sense and impossible to locate the problem when its so random
