I've just signed up to fibre broadband and pluged everything in, unfortunately I have to reinstall my printer everytime I turn the supplied router off. ( I have to turn the router of every now an then )

The router is Technicolor TG582n FTTC does anyone know how I can program it make the printer Local IP stay the same or can someone recommend a different router, this one seems pants anyway.

Thanks for your time :)

Check the manual of the router on how to assign a static ip address. Or the printer manual for how to set a static ip address.

The easiest of the two would be to assign a Static IP address to the printer, as it sounds like it is currently using DHCP.

Assigning a static via the router, would require the use of Bind IP to MAC, which would allow the printer to stay configured as DHCP, but would always allocate it the same IP based on the Printer's MAC Address. Note this is usually slightly more complicated, and depending on Router not work properly.
 
99% of routers allows MAC address reservations and this would be the best way to go.
Either that or reduce the DHCP address range allocated by the router and set a static IP to an IP outside the range but still in the same subnet
 
hmm just read this

he TG582n web interface is pretty restricted - you can't set up static DHCPs from it - you need to use the command line.
Telnet into the router (same name and password as the web interface) and then do the following:

dhcp server lease list (lists the current DHCP clients)
dhcp server lease delete clientid=xx:xx:xx:xx:xx:xx ( xx etc. is the MAC address of appropriate client from above list - deletes the current lease)
dhcp server lease add clientid=xx:xx:xx:xx:xx:xx pool=LAN_private addr=192.168.1.x leasetime=0 (adds required IP for appropriate client with infinite lease time)
saveall

Then reboot PC or whatever to get the new lease.

Can't be doing with that !
Apparently the router is prone to failure anyway.
Can someone recommend a router which can fix the printer IP addresses.

Assuming he can get into the router, and the options are available - guessing this is an ISP supplied router based on OP.

With MOST home routers reducing the DHCP range is a non-issue, as any IPs in use will be automatically excluded from the DHCP pool.

And even if not, then use an IP further up the range e.g. 192.168.1.250 for example based on standard consumer range - unlikely that the OP has 250 devices all on DHCP, and DHCP leases will expire and reuse earlier IPs.
 
does the printer have an interface where you can assign it a static ip. That is what I have done with all the networked printers at our office. Otherwise yea just use the router to manually assign, based on the clientid.

I said it was the best way to go, I didn't say it was possible for the OP as they've not give us enough info.

Also, not all routers give out addresses in a linear fashion so having 250 devices would be irrelevant as the printer address if in the pool could still be assigned by DHCP.

@MrBlobby
You'd only have to do this once (unless you factory reset the router or it dies etc etc), not every time you restart the router.

In my experience (again not exhaustive) the routers that I have used (Draytek, Netgear, Dlink) tend to give them out in a linear fashion, and they are also not fussed if there is a static IP address used within the DHCP pool *providing* the static IP is already in use e.g. Printer is always turned on - in hindsight this was an assumption that may not always be true.
 
To be fair it's not that common but not unheard of. I've never used a Technicolour so I can't comment but as this is exactly what reservations was designed for, it's a good place start :D
 
Static IP is the best way to assign devices which are used like printers, fax machines, etc. You can give a static IP to everything and disable your DHCP.
