Frequent drops in connectivity today
I'm on a vpn from my home and am experiencing frequent drops and lots of lag in my wireless connection today. I used ping yahoo.com -t and it shows a time value up to 220ms on some pings when it is normally 52ms today.
I looked at my router's log and see the following entries:

What can I do to resolve this? I saw elsewhere that a static IP can be set on my laptop but since I am VPNed into my work network I'm thinking this could foul up my ability authenticate...no idea..just a hunch.

The telling factor is the wireless, if you can, check the wired connection. See if there is any significant difference between the two. Most at-home telecommuting jobs I've helped provision usually state they want the worker on a wired connection due to issues with wifi.
Setting up static IP on a device won't affect your VPN if it is using a package like the Cisco Anyconnect software, the static IP is only for your local network. Most VPN clients will install a second software network card that the VPN goes through. However, static IP won't change the issue you seem to be having.
I also see that you typically have at least 1 T3 timeout a day (you gave the modem log) on the 11th you had 2. I'd check your physical connections, if your modem is on a splitter with a cable box, I'd see if there is a way to put them each on separate coax jacks/outlets.
