Guys, if your ISP is renewing your IP lease rapidly. Then your IP is changing rapidly. That means your posts will be broken etc. Some of your routers have a setting where you can increase the length of your IP lease. Try increasing that. 86400 should be enough.
When they do this, they eat up your gigs available. It is your ISP ATT, Verizon etc. using your gigs, because you will retry and retry. Then oh my you used up the 10 gigs on your account. Please buy again. Think I am kidding? They really do that, and it is part of the business plan.
