If you actually upgrade your routers 30 times a year, you obviously do not mind wasting your time.
There is no reason to upgrade a router unless it is broken or the new version has a particular feature you need to use.
Do you think that they come out with new versions every week or two expecting that everyone is going to want to upgrade their routers for fun? The new versions are to address "specific issues".
You are opening a "pandora's box" of potential new bugs for no good reason, unless as I said, you must not mind wasting your time, and therefore, pressing the enter key a few times will just add to the fun....
Sorry to rant on you like that. Maybe I should take my prozac.
