Hopefully I'm not over stepping any boundaries asking for some help on my first post here. I work for a small company that has had telecom come in and setup our VOIP and LAN it works fine apart from a couple of issues which telecom doesn't seem keen on fixing.
When we connect a new printer by wireless they show up as a connected device with an IP address on the Telecom Pace V5542 and can be pinged through the Paces interface, however when we try and connect to them from a desktop/laptop also connected by wireless to the Pace they cannot be pinged or seen for around 12 hours then they start responding and can be used - problem here is they like to drop off randomly again so we can loose the printers for a day randomly.
Current connected laptops also cannot ping each other but still have access to the internet. I connected a laptop by Ethernet as well just to see if that would make a difference at all which it didn't, it was dished out an IP address and could access the internet but couldn't be pinged.
I don't have alot of experience with networking so I'm a tad stumped, our Business hub rep has suggested to call an I.T company which to me doesn't seem to be an acceptable answer seeing as they were in-charge of the setup.
The gear that we have is VDSL > Telecom Pace router (all laptops printers connected wireless) > IPECS POE Switch for the VOIP phones > Connected to this switch is the PBX and Cisco 1941 Router which has a 5mb line for the VOIP traffic.
DHCP is controlled by the Pace
If anyone has any input it would be appreciated
