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.
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 .....
