Connecting to the printer ... ?

[lupedelupe]

This is driving me in-$#@%-sane.

Have had all devices networked wirelessly without any internal issues for some months now. Replaced ageing and somewhat dodgy router/modem with shiny new one, and a whole lot goes to hell ...

In summary:
Old router gave some internet connectivity issues, and based of input from various sources opted to replaced with N-tech model.
Internet connectivity seems fine and stable with new router, but having issues with ONE computer and printer maintaining wireless connectivity.
Connect computer via cat-5: fine
Connect printer via cat-5: up briefly (via router), then connection gone again
Changed router to run G-mode, computer - for now - seems fine on wifi; printer still loses both wifi and cat-5 connection after some minutes.

This baffles me. What the hell will kick a physically connected printer off a router? Computer connection to router (and beyond) fine, yet after 10 minutes or so it is unable to sniff out the printer - which is still connected to the router via cat-5.

IP adresses are assigned dynamically, and Lease Time set to Forever.

I'm lost. It used to be so simple :wtf:

Perhaps the issue lies with the printer? It's all I can think of.

Part of me also thinks so ... yet it has functioned perfectly for months without a single problem connected to the previous router (wifi). Bizarre.

Here's a reach (and I fully expect the network guys that actually DO know what they're on about to point and laugh at me): what are your DNS settings? Specifically is the shiny new router pointing to itself for internal DNS, a setting you sometimes see, to wit:



Also, when network weirdness creeps in, I'm always fond of a quick round of 'netsh int ip reset reset.txt' but that's just me.

Which router did you put in?

Belkin Surf N300.
HP CM1415fnw LaserJet Pro printer

Various other devices connecting via wifi (they all seem fine).

As a start I'd assign a static IP address to the printer. It might be going to sleep after a few minutes and then gets assigned a new address when it wakes up.

Okay ... just did that. Holding thumbs ...

By the way, thanks everyone for your input so far.

Try changing the 10.0.0.1 IP to a more common 192.168.0.1 IP...might just help.

Completely off track...

Can you ping -t the printer's IP address(es) and see if it's still contactable when it becomes unavailable?

Yes. That's the part that baffled me.

Have since updated firmware, and things have gone downhill rapidly. All indications are that something has gone very wrong with the (5-month old) printer itself. Off to repair then ...
