2.4GHZ SSID won't work when encyrpted

I have been using the DGND3700 wireless router/modem for several months and had been very happy with it's performance until recently.
As of 23/6/12 I am unable to reliably connect the 2.4 GHZ wireless SSID whilst using any type of encryption. The 5 ghz SSID continues to work flawlessly.

If i remove all encryption both my Astone Media player and Playstation 3 are able to connect and maintain healthy network speeds. As soon as I re-enable any type of encryption I am still able to connect to the SSID (although sometimes with difficulty) however the connection speed is throttled so severely that it is not possible to use either device. When streaming a video file it will often play for a few minutes before stopping. When testing the connection on the PS3, the upload and download test will fail.

I have thus far tried the following:
- Check for new firmware, none found (currently using V1.0.0.17_1.0.17)
- Reset the router to factory settings
- Changed the encryption type
- Changed the mode
- Changed the broadcast channel
- Used different passphrases
- Rebooted the modem/router
- Rebooted the system
- Disconnected modem/router from PC Ethernet port
- Auto & manual DHCP setting set up (from wireless devices)


After trying all of these things I am still finding that the 2.4 ghz SSID will only work properly whilst no encryption method is used. Once encyrption is re-enabled the connectivity fails:

PC details:
Ethernet adapter: Netgear GA311
Windows Vista 64 bit
Wireless Card Access list is disabled
No port forwarding has been set
No IP addresses have been reserved
Use router as DHCP server is set to on
UPNP is on

I have logged a call with negear support but any other advice would be appreciated.

Have you tried a tool like vistumbler to see if your wireless security changed or your signal is less than before.

Check if you have an x near connections saying your securities incorrect(you couldn't miss it if it was there). 17's where I had my blip and got stuck with tkip till downgrading or beta 4.

I hope your problems not mine but take a check at your wireless signal/security and get back to the forum.

Try going back to the .12 firmware. It cleared the problem for me. It will be interesting to see if Netgear can actually fix this device with a firmware update as they seem to be just shooting in the dark with beta's that don't appear to be really fixing things. The .17 firmware has been out now for at least 5 months and no production firmware update is in sight to fix all the issues people are having with this device. If you're still under warranty you might want to consider having Netgear replace it with one of the new DGND3700v2 devices. We're really not seeing any issues being reported on that device.

To add to my previous reply I will say that Netgear has had time to start reworking their website so that we no longer see the release dates of firmware. Presumably Netgear would rather spend their time moving and changing their website rather than fixing the issues with their devices.

Re: 2.4GHZ SSID won't work when encyrpted

Ok, i downloaded and installed vistumbler but it doesn't appear to find any APs.

Silly question, I guess the PC running vistumbler needs to have a wireless adapter in order for it to find SSIDs? The PC i am running vistumber on has the modem/router connected to it via ethernet only?

Re: 2.4GHZ SSID won't work when encyrpted

where would i find the .12 firmware. The device came with .17 and when i visited the support page no mention of .12. Is .12 applicable outside of north america?

I have flashed the firmware back to version .12 as advised by the Netgear Support Specialist and found the same problem persist.

They have since offered a replacement unit.

Re: 2.4GHZ SSID won't work when encrypted

Just in case...

If you change the encryption, without changing the SSID, you will need to modify the connection settings.

Personally I would suggest the easiest methods are either to use another SSID or delete the existing entry.

Yes you need a PC with a wireless adapter. You may have to pick it out of a list but thats not to problematic.

I'm surprised they didn't throw beta 4 at you.

Keep us posted after your rma.

Re: 2.4GHZ SSID won't work when encyrpted

Hi Scubbie, thanks for the suggestion but if I could just ask you to clarify.

Are you saying that any time I change the encryption type or passphrase I should also change the name of the SSID?

So for instance if the SSID is 'Netgear' with encryption of WPA2-AES and I want to change to WPA2 TKIP I should rename the SSID to Netgear1 at the same time?

Is this for the benefit of the router itself or the wireless devices to be connected to it?

Also thanks techman. The penny dropped about 2 thirds of the way through writing that post but i figured I might as well continue writing it. I did run Vistumbler and it did find the wireless network in question with 90% signal strength on channel 4 but I didn't really know what to do next.
I do believe the router was stuck on TKIP until downgrading to .12. .12 seems to have corrected the security, now AES, but not corrected the problem.

Should I continue mucking around with it or simply wait for the RMA and a new router? Are they likely to give me a V2 or another V1?

If you can get an rma do it and try to ask for v2 at least if your outside the US.

The wirelss should read ccmp with aes enabled on vistumbler.


If you can get shipping waiver and you have a backup router ,go with the rma. You have 6 months software before they start to turn you away. If I was still under they'd probably rma me no questions asked.

Good luck...

Re: 2.4GHZ SSID won't work when encrypted

Ok, perhaps this will help:

Starting point:

SSID = Netgear
Encryption = WPA
Password = mypassword

By changing the encryption only to WPA2-AES the computer will fail to connect as it wants to use WPA. Delete the SSID from the list of approved connections and reconnect as if for the first time. You could edit the details in the computer and tell it what encryption is now being used. By following the 'as if for the first time' procedure I am simply avoiding possible mistakes.

Alternatively change as follows:
SSID = Netgear1
Encryption WPA2
Password = mypassword

Computer will see this as a new connection and all you do is connect to it is if for the first time.

Re: 2.4GHZ SSID won't work when encrypted

Techman and Scubbie, thanks for your help guys.

With regard to the RMA Netgear have advised they can only provide like for like. i.e. version 1 for version 1. I am going to try exchange at the retailer and see if i can swing a version 2 that way.

With regard to the SSID name change and deletion/creation of a new known access point at the recieving devices I have tried that several times without sucess.

I am able to connect to the network successfully from a media player, PS3 and my smart phone however the speeds are extremely slow (<500 kbps) and the connection drops out completely after a few minutes.

Anyway, thanks guys. I'll try the RMA and reprot back...Let's hope it is the router and not something trivial. The fact that Netgear offered a replacement after trying 1 possible solution suggests perhaps they know it to be a common fault with that unit.

Scubbie at least in my problem that just wasted time with the tech. I hope though it helps for some other solution. For me I think the tech was just making sure it wasn't human error.
