Hello,

I'm using PPPoE to connect to the internet and I'm running into intermittent authentication problems with WR941ND. When the upstream router (ISP), requests authentication using, my WR941ND router sends a response, which gets rejected. See the syslog below ...

However, when the upstream router requests authentication using PAP, the authentication succeeds. See syslog below ....

Is it possible that during CHAP, the WR941ND is miscalculating the MD5 checksum (possibly by not including some info such as password?
