SonicPoint trouble - Wireless Router suggestions?

[Kayos]

Hey folks

We updated the wireless in our office (about 100 people) from HP devices to SonicPoint-Ne (model APL21-06E) and have been having some regular wireless issues ever since. Specifically, when connected computers could not always find the server shares (sometimes, they could) but could still connect to the internet. Connected to the ethernet cable they had no problem. We have investigated a number of issues and done all we could to troubleshoot this and now today none of my apple devices can connect to the wireless. They connect, accept the password but I only have a self-assigned IP.

I read in a couple of places about Apple compatibility with SonicPoints (here's one about iPads: https://www.fuzeqna.com/sonicwallkb/....asp?kbid=8091 and another about someone's MacBook: https://discussions.apple.com/thread...art=0&tstart=0)

After all this I am done with SonicWall altogether and want to replace my wireless with something that works - any suggestions?

Thanks
