Thank you for the info. So before you were having general connections problems, and not it seems isolated to wireless. The first thing that comes to mind is a wireless interference issue. Perhaps the new router is programmed on a wireless channel that other routers in your area are using.
- How much experience do you have in networking? Have you used the routers 192.168.x.x before?
- What model is the new Cisco device. This one? http://www.cisco.com/web/consumer/support/modem_DPC3825.html
- When the wireless has issues, does the wireless go out on all the devices at once? Is it worst in certian areas? Does it seem to happen at a certain time or when you do a certain thing?
- Do you pay for Cox Home Networking?
