so that mean... no old TP-Link router can get upgrade?

@ic3b34r Media made a big fuss about this vulnerability, it's not like all your wireless communications are exposed and your network can be hacked and get intruders inside (I've read a lot of crazy headlines). It's just one buffer than can be eavesdropped when WiFi connection is dropped and then reconnection occurs.

The attack starts by forcing a device to disconnect from the WiFi access point, then the device will try to reconnect as usual. In the middle of those actions, a pending WiFi transmission buffer is sent unencrypted. The probability of that buffer to have sensitive information is almost 0%, especially when sensitive information nowadays usually travels through end to end encrypted connections (HTTPS), so there would be no information at all in the buffer worth trying to attack.

Plus, to really get more than a buffer it is necessary to trigger the disconnection/connection multiple times, and anyone would notice if their WiFi starts to go on and off repeatedly. Not a very stealthy attack. Again, if your connections are encrypted (most should be!) those data buffers are just gibberish.

Another important reason to make sure we are using HTTPS sites and services. In fact, I don't get why the administration site for TP-Link routers do not default to HTTPS ;) (or at least recommends you to turn it on the first time)

I hope your router firmware gets fixed if it's needed, but just wanted to give you some peace of mind meanwhile. It's not as most news sites or blogs say.

Thank you, but even old router(Archer C7v2 and C1200) will get a new patch? or just new AX router?

Thanks
