WiFi hangs

yenoah

I'll try to describe my setup as best I can. My network has the following elements.

Netgear DGN3500 Router,
Nas wired,
TV set top box wired,
Win7 laptop wireless (using Intel Centrino Advanced N 6230 wifi card).

Whenever I do heavy data transfers from/to the laptop, the network might hang. If it does I have to restart various elements to get ti working again.

Where would I even start to troubleshoot this and how? I'd be very grateful for any help cos it's a right painn

Try using a different wifi channel. The one your using (probably 11) maybe congested. If you've a baby monitor change it's channel too as these are terrible at interferring with wifi if set to a similar channel. Play around with the settings

This app may help with identifying the channesl used by other wifi routers around you:

Hi, thanks for the reply. Router is set to channel auto. I live rural. No baby monitors or anything on the 2.4GHz band anywhere near me. I don't think this is the issue.

Check to make sure the router is broadcasting in Wireless N mode.

Have you checked to make sure you've the latest firmware and drivers for the modem and network card?

Try disabling your antivirus temporarily when you're transferring files too

No, see I think this is gonna be more complex than that. I don't run anti virus. Router is pumping out 300mbps and wifi card connecting at 300mbps. I always have latest drivers / firmware.

I saw elsewhere someone suggest Ctrl C/Ctrl V was quicker then drag and drop. Cant explain why. You could also see if teracopy might help here too.

And one other suggestion was this:

disable the autotuning feature

I'm not specifically having issues with file copying, usually the thing hangs when streaming or using DLNA.

I saw that article alright on my travels, I'll give that a shot. Hey thanks for all your replies, much appreciated.

No problem. Let us know what works if you fix it.

Well that auto tuning thing didnt work either. Just ran a stream as a test and it hung after about a minute (with auto tuning disabled).

So does it happen with lots of small files and single large files? Or does it only happen with one or the other?
