Have a mifi2200, cannot login in to a specific drop down site on my online banking web page, says cannot find site, other links in the drop down link menu load immediately,
There are no reported incidents of website limitations with the MiFi 2200. My guess is that your banking website posted a dead link. Contact the banking support site and see if they can resolve this for you.
A good way to confirm if this is a MiFi 2200 problem or not would be to try and access the same link from a totally different internet connection. For example at a coffee shop or the library. If the site is broken from those locations then it is a banking website issue and not a MiFi issue.
