Hello,

I have been working on a site I have installed Sonic Point access points.  I also have 25 new Dell Vostro 3550 that have Centrino N1030 adapters.

It appears I am in a congested area so after I have called Sonicwall for support they suggest I change my wifi  settings to 40mhz - wide band to relieve some interference.

Standard Settings - 20mhz standard:  I get proeblems with slowness (1mb to 11mb speed connections).  

Wide Band - 40mhz settings: All 25 of my new Dell Vostro 3550s that have the Centrino N1030 wifi adapter can't connect.  I can connect with a 5 year old laptop and with my 6 month old Dell Latititude, that has a different adapter.  SonicWall advised that devices that cannot support wireless N will have problems.  I thought to myself, I have new laptops with wireless N, that should not be an issue.

I have a few thoughts for fixing the problems:

1. Try different access points - perhaps SonicWall sonicpoints are the right fit for this congested area. I like sonicwall and their product appear to be good. I am wondering if I am fighting the obvious problem.

2. Fix Dell Centrino N1030 - I am working with Dell support but I have read the internet and see a mix of reviews and not sure what to believe.  I have turned off the bluetooth settings to see if it will work.

I thought I was getting the "right" equipment but something isn't matching.

Please suggestions!

Also, I have read using 2.4ghz with wideband settings at 40mhz is not a good idea.  Not sure why can anyone elaborate?  Is it bad?

Oh yeah, 5ghz won't work .....
