I'm very sorry. After a few more hours of troubleshooting, it appears it was a bad switch in my network. I put an old one in, and all is working well at the moment. I don't know why it started acting up now after I installed the new router. I did just install that as stated earlier in this thread so I thought it was the cause of the issues. ...bad luck, I guess. Again, sorry to take your time. Thanks for your help.
