info on dropouts

[blsquires]

i had a customer that was complaining about scan to email dropping off and very slow.their IT said it was the copier that was at fault i checked the machine and as i got to the web page i was checking the settings and it dropped out.
after contacting their IT we went through everything together .their server was at the IT companys premises.when we pinged the ip address for the scanner it was losing packets and was very slow.he went through all the connections and found that there were mobile phones using the same ip address so he locked the ip address to the scanner.i went round the office and turned all the phones off and restarted them and all was ok.
just thought i would let you know in case you have a mystery scanning problem

If they can, they need to Pair the MAC ID's with the IP Address so everything is static and DOES NOT CHANGE!!!

Gosh I've had a similar situation like that before many times.

Never ever place a printer statically within the DHCP range. If you can't work out what the DHCP range is then check the IP's on some of the clients computers and if for example their IP's that are assigned via DHCP are below 100 then make the printer's static IP in over 200.

If there is no I.T. rep and I cannot gain access to the DHCP server, I usually just make the IP of a printer between 240-250 as that range is usually out of the DHCP scope. Of course it also depends if the client has custom subnets, but if that's the case they would actually have an I.T. rep.

Had several problems stem from this exact issue. When I started working on copiers, a lot of ours were setup with static IP's in the DHCP range. The guy that set them up would just ping a close IP address to the computer and see if something was there - if not, that was the copier's IP now. Most consumer routers will not assign addresses above 200, although some of the DSL combo modem/router pieces of junk work down from 254 instead of up from 1.

I got into the habit of setting most of our copiers up as .231, except when that wasn't possible or if the IT guy had a specific IP address in mind. It has really cut down on calls for scanning issues.

I'll admit though - I've never had dropped packets happen as a result of this. I would be able to ping the printer IP, but not bring up the web interface. In my experience, dropped packets are always a connection issue - be it a bad wire, poor signal for wireless, or a bad port on a switch.

Dropped packets would make sense since both devices were trying to fight for anything that the router was sending to that address.

Re: info on dropouts

Have the following IP Address segregated the following way:

-Range specific for wired (DHCP).
-Range specific for wi-fi (DHCP).
-Range specific for wired (Static).

Any halfway decent wired/wireless combo *should* be able to accomplish this task!...The *bonus* would be to couple the machines MAC ID with a Static IP!
