HI,

I have just looked at the Event Log in the router.

I see a couple of entries that refer to LOGIN, i.e.,

'User tried to login on [HTTP] (from 192.168.1.64)'.

This is not my router's address.

Can anyone explain this

[roseway]

It was 'from' that IP address. That's presumably the IP address of the computer you accessed it from. If you type ipconfig in a command line window you will see what the IP address of the PC is.

[anon_private]

Thank you.

Is that a permanent address, or can it vary?

Best wishes.

It depends on how the router is set up. The router is (by default) set up as a DHCP server, that's to say it supplies and keeps a note of IP addresses for any computers which connect to it. This service can be configured to always allocate the same IP address to connected equipment, or it can simply supply any number out of its pool of addresses. If you've only got the one PC it will always have the same number, but if you have more than one then it may depend on the order in which you boot them, depending on how the DHCP server is set up in the router.

Thank you.

There is one pc that connects to the router on a daily basis. and a laptop that occasionally connects to this router.

Does the following part of the IP address always and only apply just to the home pc:

192.168.1

[roseway]

That's called a subnet. On a network, all connected devices have to be on the same subnet, and the DHCP server will have a pool of numbers to allocate to connected devices, all of them on that same subnet. The one you quote is quite commonly used with domestic routers, but some routers use other subnets.

You can read more about the subject here.

Thanks again.

On a related point.

The power in the house needed to be switched off for a few minutes.

When the power was restored, I checkd the DSL connection in the router and Uptime had not seemed to be affected. I would of thought that it should have disconnected at the exchanged when the power was cut, then re-connected on power-up.

I looks as if I don't understand uptime. Please can you clarify the definition.

Best wishes.

Certainly it's true that switching off power to the router, then switching it on a bit later, would have resulted in loss of the ADSL connection and a re-sync. What I imagine happened in your case was that the power wasn't off for long and the ISP's equipment didn't notice that the connection had dropped during this fairly brief interruption. So as far as your PPP connection (the connection to your ISP) is concerned, the service was never interrupted and the uptime wasn't affected.

[orainsear]

Seems a bit odd.  I'd have thought that as soon as the power went off the PPP session would terminate; re-powering the 585v7 would see a resync and then reinitialisation of the PPP session, and that the uptime would reflect this.

[anon_private]

I am told that the power was off for a few minutes. I will check further to see if the power was off downstairs where the router is. It was certainly off upstairs.

Thanks

I have now tracked down the bloke who switched off the power.

Evidently, he was going to switch off all the power, but then decided to only switch off the power to the upper floor.

So the router would have remained powered.

Hence, my log confirms this fact.

However, this thread does raise the question of whether a cut in power for very short periods of time might not be recognised as a break from the router to the exchange. I wonder?

Best wishes

[roseway]

It's certainly the case that very short-lived ADSL disconnections don't always result in a loss of the PPP session. But if the power is switched off, then it takes a significant time for the connection to be re-established when the power is turned back on, so what orainsear said is probably right.

[anon_private]

Thanks for responding.

Do you mean very short disconnections without loss of power. Or very short disconnections due to loss of power.

What do you mean by 'very short dosconnections'.

Thanks again.

[roseway]

I can't quantify 'short disconnection'. I suppose it depends on how frequently the ISP equipment checks the connection, and exactly where in that sequence the disconnection occurs. If (say) the ISP samples the connection every 15 seconds, and a disconnection/reconnection occurs within 10 seconds between samples, then there won't be a loss of the PPP session. There's no complete answer, I'm afraid.
