Problems with the wireless version 4

I am with the following problem: I used version 3.30. I’ve been having some more problems with some automatic route in ospf, when leaving the IPs operating the routes were not undone in a few occasions, and it generated inconsistencies in the routing. the staff of the forum referred me to use version 4. which would solve my problem, actually solved. more with version 4, I came across another problem. wireless links with various levels of signal optimism is falling very Clockrate of anything. I can not go back to version 3, it will come back to have problems with ospf. Anybody know how I can resolve the issue in the wireless version 4??
