I have an account with TDAmeritrade for my IRA stuff. Something weird happened over the weekend, and for the life of me I cannot figure out what is going on. Hopefully one of you guys have some suggestions. PROBLEM: While starting TOS software, it hangs as it checks for a new version of the software. I can close TOS with no problem. It just sits there like it is trying to make a connection and it never does. Do not get any errors either. Some debugging I've done: 1) Internet connection is fine. 2) Worked a few days ago. Did nothing to my computer or router since then. 3) Laptop that has TOS on it does the exact same thing as my desktop. 4) I can disconnect my router and connect cable modem directly into computer and everything works fine. Since #4 is true, you'd think it is a router problem. However, my internet connections are fine. I did not change any router settings. I've called TPLink tech support and they basically had no idea. Anyone have any suggestions, or do I need to buy a new router?
