pn51e550 wireless network help needed

Hello AVS community. I hate to make a new thread for this but I am stumped. I have a pn51e550 display that I used to connect via wifi to my router but then I switched my ISP and used a direct ethernet connection to it in roughly July. I now have moved and need to connect to a different router via wifi again. When I go to 'Network Settings' and start the search for a wireless router half the time it will search and I will see the routers in my area for about 1/2 a second then it closes out of the menu and back to the tv. I do see my router but its too brief to select it. I am connecting to my router with a 25' cat 5e cable at the moment but I do not want to have it running through the hall. Has anyone had wifi issues with the 2012 samsung tv models? I was thinking of doing a factory reset but it says it does not reset network settings.
