Well, after some business and personal travel I returned to my home office to again fight the battle of getting the 5224 connected...no luck so far.
1. Have gone through the default reset process (several times)...no change
2. have connected a laptop through the phone's pass-thru port and can easily get to the internet (so that seems to be telling me that the cable router isn't the problem)
3. brought the phone in to the office of the company I work for, and while I wasn't present while it was done, the IT guy says it worked fine there.
4. brought the phone home, used the cable that worked for the laptop, same problem.
Any other ideas please?
Thanks,
Art
