Is it typical for salary negotiations to take over two weeks?

I interviewed with a company and received a job offer about two weeks ago. The recruiter mentioned that the hiring manager was quite impressed with my qualifications. However, I later discovered that the top salary band for the position is $11,000 lower than my current salary—something the recruiter hadn’t mentioned before. I decided to negotiate and asked if they could match my current salary. The recruiter seemed to expect this and assured me that the hiring manager would try to accommodate my request and get back to me.

Since then, I haven’t heard anything for two weeks. I followed up with the recruiter last week, and he mentioned he would have an update by the end of the week, but I still haven’t received any news. Is this kind of delay normal? I’m starting to feel frustrated with the lack of communication.
