Sonicwall NE Slow Speeds

Hi,

I have a Sonicwall NSA240 which I have 2 SonicPoints NE's on.  What I'm running into is
I get slow speeds on any iPad's iPhones and Androids (Samsung Galaxy S3) connecting to the internet, while  I test on my PC using speedtest.net, I get 20Mb download and 2Mb upload.
(The results  on the iPad/iPhones is around 4-7Mb for same test - I make sure I test using the same servers)

I tried messing with all the advanced features on the Radio, tried going to Auto channel and Auto Radio Band (which going on 40Mhz yields VERY slow speeds, under 1Mb - but this is a known problem with apple products)  I dont have " Enable Aggregation " enabled or " Enable Short Guard Interval "  there are a bunch of other AP's in the area, but according to the Sonicwall RF Analysis page channel 8 is clean, however that doesnt really make much of a difference.  

Any ideas?  TIA!

my windows PC is wired, but I can connect a USB wireless card to check,  what I have is iPhones, iPads and androids connecting,  and all of them have N, I tried switching the radio to N only, in fact that's what it's on now.   but I should be getting connectivity speeds of 100+ max 150mbps,  and it's connecting at 65mbps according to the android client and the sonicwall station status, and that wouldn't matter if at least I got the same bandwidth out, but as said above, it's not.

Yes, I saw that, and if you take a look at my screenshots, I have it set as per that KB, and I may add that I didnt previously, that I'm sitting 6 feet away from that sonicpoint, so there isn't any interference.  However that performance is all around the same, even when I go to another location.  
Is this a sonicwall thing?  I've set up Cisco wireless solutions with no problem, and btw I got rid of a NetGear N900/WNDR4500 that had great speed at that same location, so it's not the location or interference.

Yes. I'm wondering if this is a sonicpoint thing, as I've been reading alot of bad things about them.  my statuses are showing at connect and transmit of 65Mbps but when I do a speedtest, at best I get 10Mbps while the desktop computer running (wired) windows 7 is at 20Mbps.  

I'll bring my laptop home today and try it, I have win7 on it, and see what I connect at and what speed I get, if that goes fine, then it's definitely a sonicwall/apple problem, but I also have a Samsung galaxy S3 that gives me the same results, so I'll have to see if indeed the laptop will be different.  

It's not the sonicpoint either as I have 2 of them and they both give the same result, and I have the latest firmware on it, sw_spn_eng_6.0.0.3_6.bin.sig, which I guess came with the sonicwall (SonicOS Enhanced 5.8.1.9-58o)

So far what would you say is the problem? sonicpoint hardware?
Your help has saved me hundreds of hours of internet surfing.

It sounds like the Sonicpoint. Have you tried calling Sonicwall support?

No, that's my next step, after I do the test with my laptop.

For reference, do you have a connection to the internet faster than 20Mbps? if so, can you run a speedtest through any apple device and see what you get?

Hi carlmd, figured it out, someone connected a cordless phone base 2 feet away from the AP, looks like that had enough interference to cause that slowness. I moved it away, and right away the network cleared.  see attached.  the ipad has a tx speed of 241Mb now...
Ill award you the points as you were the only one kind enough to help! thanks,

when troubleshooting wireless networks always look for interference.
