RE: SIP-T43U causing pc to lose network connection
Hi,

If the phone works well with a separate power adapter, then it makes no sense to fix the firmware.

Make sure that the PoE switch can supply enough power and that the wires in the network cable between switch and phone are made of 100% copper and not an alloy.
Use an 802.3at PoE switch and CAT5E or better cable.

Thanks for the reply.
We are using the cable that came with the phone. If the manufacturer provided it, it should be sufficient.
The switches are new and should be supplying enough power. The phone requires 5 volts, 1200ma and the switch is rated at 48vdc, 30 watts. Are you saying that if the power demand on the switch is high, it will disrupt the network communication on the pc?
Using the phone with the AC adapter works when I have an adapter. Unfortunately we had some adapters go missing and now I have a phone without any adapter. Also, I'm finding that I have to install an non-POE switch because I am connecting two lines(one from pc and one from the phone) to my network. I haven't tried using the AC adapter with the single line(network to phone, phone to PC) approach. Because the phone was interfering with the pc, I assumed that it should have a separate connection to the network).
