Windows 7: Edimax Wireless Card EW-7718IN installation problems

Edimax Wireless Card EW-7718IN installation problems

I bought an Edimax WiFi card (EW-7728IN) which supports Win 7 to replace an earlier WiFi card unsupported by Win 7. In the initial installation I left Windows to find the necessary driver, which it did and reported a successful installation. However, no wireless signals were picked up and when I went into the Network Centre and looked at the adapters, the card was recognised but reported as Disabled. I tried to enable it and Win 7 went through Enabling to Enabled but the icon for the adapter continued to show Disabled and no wireless signal was detected. Looking in Device Manager showed the WiFi card was detected with no exclamation mark next to it and it was reported to be working normally. Win 7 wireless diagnostic procedure suggested there may be a driver problem but gave no solution.

I uninstalled the inbuilt MS driver and then went to install the Windows 7 driver provided by Edimax and written by Ralink. Essentially the same thing happened and installation was reported as successful but despite Device Manager reporting the card to be working normally it was shown to be Disabled in the Network and Sharing centre. To give as much information as possible, the following data summarises the situation:

I have used the Windows 7 driver (20091028) provided on the Edimax website.

Under Device Manager it reports that the card is given as working normally and the driver is given as Edimax 802.11n PCI card and the driver given as provided by Ralink Technology, Corp., driver version dated 4/8/2009.
The Win 7 diagnostics from within Device Manager gives the following information: Network adapter Wireless Network Connection driver information:

The Network diagnosis gives CCX Diagnostic test failed!!!

Is this likely to be a driver problem or are there some arcane settings within Win 7 that is preventing what is seen as a successful installation to be effective.

I would be grateful for any help you can give me.

don't let windows look for the driver if the adapter came with a cd put it in and go to device manager and choose update driver then choose to install driver manually and point to driver on cd and install that way if you did not get a cd use link to download driver file and extract that and point to it

Tried installing directly from the latest Edimax driver

You can see from the top that I have tried both the automatically installed Windows driver, which didn't work. Then I uninstalled the Windows driver provided and set Win 7 up so that it didn't automatically provide the driver. Then using the Win 7 driver provided on the Edimax website went through the same installation but still it doesn't make any difference. I thought that maybe there were traces left of the previous installation so I deleted all Wireless Connection settings in the Registry and reinstalled the Ralink Driver from the Edimax website. No change. Exactly as before - the EW-7728IN driver was recognised by Win 7 but disabled. The continuous light on the wireless card switched on but no connection and no wireless signals were detected.

Could the card be defective? Is the driver buggy? Are there any Win 7 settings interfereing with the installation?

Thanks for your interest and help.

well there is always a chance the card is bad but other people have been having problems with the ralink adapters also so maybe it's not

EW-7728IN card - RAM reduction and other suggestions

I have tried the following:

Reduced the RAM to 2Gb had no effect on the 'Disabled' status of the card.

I have tried another EW-7728IN card and that does not function either, so unless an entire batch was faulty it seems unlikely that the card is at fault.

I don't know for sure whether the entire chipset is non-Ralink but the main chip on the card has Ra RT2860T - GX30080E0 - 0810ST printed on it which seems to be a Ralink chip.

The RT2860T on the chip suggested that I try the Ralink driver for this chip. I was directed to their website and a driver called IS_AP_STA_RT2860_D-'. This was installed after uninstalling the previous driver. Unfortunately it had no effect and the 7728IN card remains visible, connected but disabled.

If the following will help anyone this is all the information I'm able to get about the network card using SIW:

It is infuriating but it looks like there are serious problems with this card and Windows 7.

Death knell for Edimax 7728IN

I guess that's it for the Edimax. On another PC that I set up for my son, the Netgear Rangemax worked fine with Windows 7. I guess I'll have to play safe.

Thanks for all the suggestions.
