Connection Issues T3/T4 Timeouts

Hello,

 

Recently moved into an older house. Over the last month have had a ton of t3 timeout, and a couple  t4s. Upgraded my router since the old one was a bit dated. Still had the same issues. Removed a splitter from the outside box, and only have 1 coax that goes right to my modem. Over the weekend I was out of town and had like 3 or 4 t3s. After being home for a little tonight had another t4 and lose connection for about 10 minutes.  Would love any suggestions! 

Edit: Before restarting my router had about 2-3000 uncorrectables across the downstream lines
