Intel Centrino 6230 dropping out with Netgear DGN2200

[a_schafs]

Hi,

I've been happily using my work Toshiba Portege R830 with a Intel Centrino Advanced-N 6230 wireless adapter with my Netgear DGN2200 home router for a while now.

I recently had to upgrade the Intel wireless drivers (to get PEAP functionality for another network) from version 14.0.2.2 to the latest 15.1.0. Ever since upgrading I can still connect to my home network, establish an Internet connection briefly but it is incredibly slow and drops out within a minute or two. Downgrading the drivers fixes the issue.

The router has been and is working fine with a no of other devices and similarly, the updated drivers work fine with other wireless networks. I've read of similar issues related to power saving settings however I've checked all the power settings I can and set them to not try and save power.

Any info/suggestions would be much appreciated.

Thanks,
Andrew

Have you been experiencing the same problem on any other wireless devices? What is the current firmware of this router? Could you also provide the network environment and how your network connection is set up?

Hi,

I've been using the wireless router fine with a bunch of other devices (PCs, Macbooks and Apple TV) - only this PC has had an issue.

In terms of more specific configuration:

Hardware Version: DGN2200
Firmware Version: V1.0.0.36_7.0.36
Security type: WEP Automatic Authentication, 64-bit encryption

All 5 devices I have are using wireless only with DHCP statically assigned IPs.

Thanks,
Andrew

Any ideas anyone else? Not being able to use the home wireless is starting to be a real pain.

Thanks,

Have you tried other encryption types, preferably WPA2, since WEP is about to start phasing out of use and will limit your wireless throughput to 54Mbps maximum?

Thanks for the suggestion, Andy. I'll try changing the encryption type and re-testing it - sounds like I should be switching anyway.

Cheers,
Andrew

If you’re not using WEP for any specific reason then it’s best to change, WEP is a very weak security encryption method and is about to start being phased out (along with TKIP), it is also not allowed to be used for higher throughput 802.11n.

Hi Andy,

Much appreciated for the tip - that seems to have done the job. I've been using the connection for an hour or so with good speed (previously it would trickle along and drop out within a couple of minutes). I should have tried this earlier but I'd got hung up on thinking it was related to power polling settings.

There was no real need for me to use WEP - it was just a legacy thing that I'd had and kept going as "it ain't broke" (until now). Sounds like it's worth making the change for the reason you mentioned. Maybe Intel have discontinued or at least stopped testing WEP support in the new wireless drivers.

Thanks again,
Andrew
