--- Comment #54 from Troy trboy13@yahoo.com 2007-10-22 17:25:49 --- Forgive me for being new to this but I thought I might mention something I noticed.
I was able to connect to bnet with 9.45 and now with 9.46 I can't. I tried connecting while looking at my packets with wireshark and I've noticed that some(if not all) packets from warcraft are being marked as having a bad checksum. I haven't confirmed that this wasn't happening before(I'm not sure of the best way to revert to 9.45), but I assume that the packets must have been fine before.
Not sure if that helps any but you can try it yourself and see.
