ICOM WLAN with a Ralink rt5572 based WiFi dongle and no router!

This was tested on Windows7 Pro SP1 64-bit and 32-bit (Hardware: Intel Advanced N 6200 AGN). It should work on any version (ex. starter); both 64 and 32 bit (will not work with XP or Vista -also do not ask me about 8 or 10).

– Your ethernet connection is working and you can already connect with ICOM via cable,

– Your ISTA-D settings (VCI config) are :
*This is not a “proper” software router, you will just get a simple access point, which is enough for another computer to connect from their end.
*Also: do not use the password in this picture!
2.Configure the network connection: go to Control panel, Wireless and sharing center, manage adapter settings. Look for your new connection (it is the one using the Microsoft virtual adapter). Open properties, then IPv4 properties.
Set a static IP address such as, subnet mask (this will be added automatically). Remember; this address must be different from your wired connection and “real” wireless connection ( in my case these are for wired and DHCP for wireless, which is not needed anyway, since this is a different connection alltogether):
*Of course, you could roll with Windows assigning the address. Based on my experience with APIPA in Windows however, I would not reccomend it. It is evil and not worth the effort.

Restart your computer (just making sure everything loads with the new settings).

3.Set up ICOM: Connect the rt5572 WiFi dongle to ICOM, connect ICOM to your computer via cable and power up ICOM by connecting it to your car. Upon powering on ICOM will load the drivers by itself, but WIFI will not work until the unit is restarted.
In your browser open: (or -this made no difference for me)

You can change and check your settings now:
– Device Configuration /mode: ISPI NEXT (so you can configure WLAN Settings)

– LAN Settings/ Discovery mode: APIPA

– WLAN: set to the correct region, set security type to WPA2 Personal, set the same SSID and password as in Virtual router (step one).
4.Test ICOM: Restart the ICOM by disconnecting it from the car and reconnecting it (still on cable) go to ICOM Confirguration Manager, run Self-Test and you should see this:
5.Connect ICOM via WiFi: Disconnect ICOM from the car, disconnect the ethernet cable from ICOM. Start Virtual router and reconnect ICOM to your car. The LAN indicator will be off. The WLAN indicator wil turn on.
*The indicator on the wifi dongle was turned off, this is normal (depends on the WiFi chipset, drivers…).
*Also observe the 3 m long extension cord!

ICOM shoud now be available in ITools and ISTA-D (Choose “Operations”, then click “Interfaces” button)! You should be able to establish connection and perform identification and vehicle test now:
*ICOM has a new IP address now (old one will be back once attach it again via cable – last one)!

That is all.

This should also work for the mini Pci cards, since ICOM mux here is just another device (computer) looking for an access point (it does not matter which interface it will use, as long as it works – the problem is providing an access point it can use on your computer).
