I assume you're talking about 1 Corinthians 14:34ff - "women should stay silent in the churches ..." and you're considering its relation to 1 Timothy 2:11-12.
I personally don't have a problem with pauline authorship of 1 Corinthians 14:34-36, but I think we fail to appreciate the context. Paul is discussing orderly worship. The particular issue seems to have been that women were disrupting the orderliness of Christian gatherings in order to ask questions about what was happening or what they were hearing. Paul felt this was inappropriate. The issue is why they were doing it. Some have speculated that women in the 1st century were generally uneducated and were perhaps making use of their freedom and equality to shout out questions during worship. He singles out women because the other largely uneducated group in the 1st century was the poor, but the Corinthian church was a bit of an anomaly in that it seems to have been a wealthier church. Corinth itself was a fairly well to do trading city. The concern seems to have been that anyone would disrupt worship - but in the case of Corinth, "anyone" was likely women. Paul's advice was "if you have questions, hold them and ask your husbands (who would have been more educated) when you get home." It sounds sexist to modern ears, but I don't think Paul meant it to say that women could not be leaders, teachers, etc. His letters are full of references to women who were his co-workers, and also to the equality of the sexes, to the extent that a 1st century mind could grasp that context. Keep in mind that immediately before those words, he's concerned about too many people speaking in tongues at once and nobody interpreting. Those folks are to keep quiet as well if there's no interpreter. Then he seems to suggest that prophets are speaking over each other. That has to be controlled. Kind of "if you're prophesying and somebody else gets a word from God shut up and let that person talk." Paul seems frustrated to me in this passage and kind of lashes out at various people he sees as bringing disorder into worship.
Although some have suggested that 1 Corinthians 14:34-36 is a later interpolation, I'd argue that it's more likely that the author of 1 Timothy lifted Paul's words from 1 Corinthians out of that surrounding context and made them much harsher and more restrictive toward women than Paul ever intended.
