[Security Flaws] Severe flaws called "KRACK" are discovered in the WPA2 protocol

Dear All,
On October 16th, 2017, an security researcher has disclosed some severe flaws in the WPA2 security protocol.
Description of the vulnerability
The vulnerability that known as "KRACK", short for Key Reinstallation Attack, will target the four-way handshake of the WPA2 protocol. Mathy Vanhoef, who published the flaw, said that the flaw may allow an attacker within the Wi-Fi range to decrypt network traffic from a WPA2-enabled device, hijack connections, and inject content into the traffic stream.
The publisher also points out that, the main attack is against the 4-way handshake, and does not exploit access points, but instead targets clients. So it might be that your router does not require security updates.
For more details, please refer to the below article published by Vanhoef:
https://www.krackattacks.com/
The following Common Vulnerabilities and Exposures (CVE) identifiers were assigned to track which products are affected by specific instantiations of the key reinstallation attack:CVE-2017-13077, CVE-2017-13078, CVE-2017-13079, CVE-2017-13080, CVE-2017-13081, CVE-2017-13082, CVE-2017-13084, CVE-2017-13086, CVE-2017-13087, CVE-2017-13088
TP-Link is aware of the vulnerabilities (KRACKs) in the WPA-2 protocol. We have published a security advisory on the official website and are working to solve the problems now.
Security Advisory: http://www.tp-link.com/en/faq-1970.html
[FONT=&]Software updates for the affected devices will be post at http://www.tp-link.com/support.html over the next few weeks.[/FONT]
Your network security is highly regarded by TP-Link.
Clarification for the WPA2 Vulnerabilities:
1. Please have a look at the article published by Mathy Vanhoef and pay attention to the QA listed at the end:
Q: What if there are no security updates for my router?
A: Our main attack is against the 4-way handshake, and does not exploit access points, but instead targets clients. So it might be that your router does not require security updates. We strongly advise you to contact your vendor for more details. In general though, you can try to mitigate attacks against routers and access points by disabling client functionality (which is for example used in repeater modes) and disabling 802.11r (fast roaming). For ordinary home users, your priority should be updating clients such as laptops and smartphones.
From the QA, we can get clear that the vulnerabilities only targets the devices act as Wi-Fi clients, including laptops, smartphones, range extenders working in RE mode, routers/gateways working in RE/WDS/WISP mode.
Thus if you're using the following TP-Link products:
(Unaffected Devices)
# All powerline adapters
# All mobile Wi-Fi products
# Routers and gateways working on default Router mode or Access Point mode
# Range extenders working in AP mode
You will not be affected by the WPA2 vulnerabilities. What you need to do is updating your Wi-Fi clients.
2. Conditions under which devices are vulnerable:
# Physical proximity: An attack can only happen when an attacker is in physical proximity to and within wireless range of your network.
# Time window: An attack can only happen when a client is connecting or reconnecting to a Wi-Fi network.
Devices affected by the vulnerability
Routers working in Repeater Mode/WISP Mode/Client Mode:

How to protect your devices
Until a software update is available to eliminate the vulnerability for your product, it is recommended to take the following precautions:
For wireless routers: Make sure your routers are in Router Mode or AP Mode, and patch the operating system of your smartphones, tablets and computers.
For wireless adapters: Patch the operating system of your computers.
Microsoft security update: Microsoft has fixed such security issues as mentioned in https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2017-13080
TP-Link has been working on affected models and will release firmware over the next few weeks on our official website.

"

I hope that if TP-Link decides this is the case for any of its products, it gives a detailed explanation of why this is not the case.

Our business uses EAP245's and it was their initial value that led us to choose them but it's this response that makes us
really regret not spending slightly more to go with the
Ubiquiti access points. If we had
Ubiquiti access points we would have been able to apply the patch yesterday and move on.
As others have noted in some other threads here, most of us smaller business users can't risk our engineering data being vulnerable, so we simply unplugged all of our access points until TP-LINK can get their act together.
I'd personally recommend that any business user seriously consider another OEM for any professional network based on this pathetic response.

That's very simple. Vanhoef, the guy who discovered the bug, is releasing scripts to test for the vulnerability. If a device is not vulnerable, there's no need to release an update.
If you don't want to take TP-Link's word for it, you can run those tests yourself. (I'm sure a number of security vendors will come up with easy to use tools if the scripts proof complicated.)

We will list the affected models after a confirmation and the beta releases should be available in the coming weeks.
WEEKS (!) Come on TP-Link this isn't something you can address over the 'coming weeks' - You have to address it NOW. Even if it's to say that nothing needs doing. Your rivals seem to be releasing patches all over the place.
Would you please also remember that customers running some of your more legacy equipment models may well be affected. It would be nice to see for instance, my Archer D9 receive an update if it is deemed necessary.
Some of us are quite happy with these legacy goods but would definitely be more than happy to look at rival products from other vendors (that have been patched) should the necessity for new equipment arise in the near future.

You are aware that Windows and Apple are already patched which means those devices have no issues even connecting to w router or access point that is not patched. Android is not patched yet and google says not until November yet 1 day after the release people are demanding TP-Link to have an update already or know when they will have one? Imagine paying for a $900 Google Pixel and being told you are insecure for the next month or deploying a fleet of Sonic Firewall devices over your corporate footprint and be told Dell has no information at this point?
Make sure you PC and or Apple is up to date and use ONLY SSL enabled websites that your passwords are sent to. Finally, let tp-link do their job and get the router patches done.

It affects the WPA and WPA2 protocols, you can tell which models are affected by reading their boxes Basically all of them. I'll gladly throw my tp link router in the trash due to their asinine response. Does anyone know of any consumer grade [wifi] routers that have patches already?

TP-Link: you were notified of this vulnerability more than 90 days ago. During that embargo period you should have researched the issue and prepared suitable updates. What the hell have you been doing?

I have been disappointed with TP-Link's response so far. This is not encouraging me to recommend them in future, despite the fact that I have had no issues with their hardware to date.
As an aside, why is this forum not running on HTTPS!?
