Comcast is aware of the issue but has not made any official statement on the issue yet. We'll keep you posted.
What are suppose todo to prevent this WPA2 Hack?
Well, the hack isn't in the wild yet, so you don't have to do anything. University researchers have just reported that there are vulnerabilities. No one has exploited the vulnerabilities yet.
What XFinity is failing to say but should say is “ until a patch is issued or the threat is fully understood all should proceed and assume that your wireless network is not currently protected by encryption. Don’t share sensitive information on your wireless network particularly if you are using a non https connection.
@XFinity, what is wrong with issuing a statement with an abundance of caution as opposed to leaving people potentially vulnerable by remaining silent.
Everyone needs to take a deep breath and stop acting as if the sky is falling. An attacker needs to be on the same Wi-Fi network as you in order to carry out any nefarious plans with KRACK.
You’re not suddenly vulnerable to everyone on the internet.
You can still take steps to safeguard against KRACK. The easiest thing would be to simply use a wired ethernet connection or stick to your cellular connection on a phone. If you need to use a public Wi-Fi hotspot—even one that’s password protected—stick to websites that use HTTPS encryption. Secure websites are still secure even with Wi-Fi security broken. The URLs of encrypted websites will start with “HTTPS,” while unsecured websites are prefaced by “HTTP.” The Electronic Frontier Foundation’s superb HTTPS Everywhere browser plug-in can force all sites that offer HTTPS encryption to use that protection.
I rent an Xfinity Arris T6862G Gateway Router. Recently reported WPA2 flaw (https://arstechnica.com/information-technology/2017/10/severe-flaw-in-wpa2-protocol-leaves-wi-fi-tra...) means that routers need to to apply fix.
Arris does not have any information on fix (http://www.kb.cert.org/vuls/id/CHEU-AS7JWW)
Please let me know when a patch will be released, instructions to access, and apply the patch.
Thanks in advance!
A series of industry-wide announcements were published regarding the discovery of several security vulnerabilities found in certain implementations of a widely adopted wireless standard, Wi-Fi Protected Access II (commonly referred to as WPA2). These vulnerabilities affect products across major Wi-Fi infrastructure and Wi-Fi client providers.
I would like to know if the cable modem/router has the most recent firmware to fix this problem?

The Krack is a man in the middle attack and only a device on your own home network would have to be 'in the middle'. your WPA2 security 4 step handshake/password is secure. The hack requires a device on your home network to be running the malware and by multiple resend requests causes the packet number counter to be reset to 0. Since the home gateway (modem+wifi) receive boot loaders automatically when available (there will be no lag when the possibllity of the counter reset has been removed).
