I have the current release firmware and have found there to be some sort of bug that wasn''t on the known issues list. I assume this is due to some attack that is being attempted, but the router will stop responding to DNS and UPnP protocols after a while. I have no idea the exact duration, or if there is any consistency to it. But having to unplug the router to be able to surf the web (without having to go by IP address only or pointing all clients to some other DNS server) is rather annoying. I also notice, when those services stop responding, that the web interface does not update or react properly. My guess would be a memory leak or buffer overflow.

I am a technically oriented user and would be very willing to perform any tests that might be able to help track down the issue (including the use of non-release firmware, if that was needed).

I''ve just gone through a move and have not hooked all my computer equipment back up. However, I''ve not seen anything else regarding the problems that I''d described. Would they have contacted me through email?

Hey Nathan,

Thank you for contacting NETGEAR Support. My mame is David, and i will be reviewing your case.

After looking at the initial E-mail i see that you have the Current release firmware the date was 9/15/2006
This indicates you have firmware version 1.0.2.4
There is a more recent firmware available here:
http://kbserver.netgear.com/release_notes/d102984.asp

Firmware version 1.0.3.5

Once you've updated the firmware you must reset the router to Factory defaults By Pressing and holding the RESET button for a full 30 seconds.

Then manually re-configure the router.

Please feel free to contact us for further support.

I already performed that procedure. I''ve been on that firmware for a while now. The trouble is, it did not solve the DNS dropout problem I have.

Hey Nathan,

Here is another thing you can try.
If the router stops responding to DNS requests
You should test the DNS servers by preforming a PING test, and make sure the DNS servers are actually responding.

If the you check the router status page, and the PING Those DNS servers.

You can set static DNS servers in the router, Its probably best for you to contact the ISP and find out their DNS servers.

Once you obtain the DNS servers from the ISP, you should test them by Preforming a PING test.


If you cannot obtain Static DNS servers from your ISP, You can use these DNS servers for testing.

4.2.2.2
4.2.2.3

If these suggestions do not work please call our support center at the following number 1-888-638-4327,
So we can collect more information about your case.

It''s not the REMOTE DNS at fault. If I manually point to another DNS server, everything works fine. However, the router, itself, is supposed to be a DNS proxy for all of it''s DHCP clients. Is it not? It sure sets itself up to be, anyway. And even works that way, for a good while. Then, for whatever reason, the ROUTER stops working as a DNS server. A reboot of the ROUTER and all is fine. Note that during this time, any established connections are still working fine, as will anything else that is IP based, rather than hostname based.

Dear Nathan,

Please call our support center at the following number: 866-246-4995
So we can determine if the hardware is defective, and issue a replacement.

Wait. If DNS drops out, due to a BUG or EXPLOIT, you think it may be defective hardware?! The established connections stay working, and anything that uses an external DNS will work, too. It''s ONLY the DNS portion of your FIRMWARE that is having issue. I''ll call, but it may be a while. My work schedule makes it REAL hard to call various support services. Web and email work best with me, for the simple fact that I can do them at any time of day or night that I have the time for.

Mr. Hartwell,

My name is Nathaniel from Netgear Level 2 Technical Support. I have reviewed your case and understand that you've ran into a problem when using the router as an unauthorative DNS server. The easiest way to resolve this problem is to stop using the router to proxy DNS lookups.

At this time there are only two options, manually enter the DNS addresses of your ISPs domain name servers into the TCP/IP configuration of your LAN adapter(s) or request a replacment unit from the manufacture.

Well, aren''t you just the brightest of the bunch. Your product isn''t working as DESIGNED, so you tell the customer to stop using it that way. You don''t even suggest getting with the firmware development team to put together a debug version that might give a clue as to what''s causing the whole issue. You people are just as bad as the LinkSys morons. They had firmware issues (the router of theirs I used had other issues that changed with the various firmware versions I used, but they suggested it was faulty hardware, too). And to think, I thought Netgear was a better product with superior support. Oh, my bad.

Mr. Hartwell,

My recomendation is intended as a workaround to immediatly remedy your specific issue with recursive DNS lookups. We cannot provide the kind of solution your are looking for because this issue is not one that we've duplicated in our labs. There are various reasons for a recursive DSN lookup to fail and we do not have a debugger available for you to troubleshoot this issue further. Thus, of the possible reasosn for this issue and their respective solutions, we are left with just two workarounds that may provide an immediatly resolution.

1: Using your ISPs DNS address, manually specify the primary and secondary DNS addresses in the router's basic settings page (if applicable) or in the TCP/IP settings of each computer.

2: Contact Netgear Technical Support by phone and refer to support case #3759015 to begin processing a replacment unit which has been authorized.

Next time you are suggesting to temporarily bypass a bugged feature of your product while the issue is still being looked at, SAY IT''S A TEMPORARY SOLUTION WHILE THE BUG IS BEING WORKED ON. The way you said it suggested something on the stupid level.

Now, seeing as how I''m not locked to a specific IP, there''s the chance that I can get on a different subnet with my ISP. My ISP has started blocking DNS lookups that are directed to server outside of it''s subnet. I run my own server and cannot use it''s DNS, for example. So, your temporary solution means I''d have to log in to the router and change the DNS entries any time my IP happened to belong in a different subnet. My frequent connection drops (lovely ISP, I know) are what I suspect as the problem. And, like a few Microsoft products, I suspect your firmware has no timeout on certain processes (which it should, just a reasonably long one).

A possible fix that you can pass on to your firmware development team is to get the latest uclinux package and base off of that. I suspect that the product is either using an old uclinux version or a completely custom code base.

Mr. Hartwell,

RE: "My ISP has started blocking DNS lookups that are directed to server outside of it''s subnet"

If, your ISP's DNS servers are blocking recursive lookups directed to the DNS server that originate from a different subnet.

You may want to use a different DNS server. We use 4.2.2.2 and 4.2.2.3 for testing, however, these are not Netgear owned DNS addresses. You'll have to contact your ISP for a permanent DNS alternative.

-OR-

If, your ISP is blocking recursive DSN lookups to any DNS server outside of the subnet from which the lookup originated.

You'll have to contact your ISP for a permanent DNS alternative that does not block recursive DSN lookups.

OR, Netgear firmware authors and tech support can get a clue and actually FIX their broken crap so that the customer DOESN''T have to jump through flaming hoops to get around a flaw in your product.

I just wonder how many people would even consider ANY Netgear product if I were to copy this entire technical submission thread and paste it on my web site.

The ONLY router that I have NO trouble with was the router *I* made with an old computer. It ran an old Linux installation, and even stayed running, perfectly, when the HD failed on me. It wasn''t until I tried to log in to the server to check a log file that it freaked out. The ONLY reason I hadn''t rebuilt that router is that I liked the idea of a small, dedicated, drive-less router. With all the problems I keep having with the various brand routers, I''m starting to rethink that decision.

Mr. Hartwell,

If your ISP is blocking recursive DNS lookups from your router, this is beyond Netgear's control and they only thing we can do is offer suggestions as to how you might workaround the actions of your ISP. However, if you no longer require technical support on this issue you may close the case at any time.

If your ISP's DNS servers are blocking recursive lookups directed to the DNS server that originate from a different subnet, you may want to use a different DNS server. We use 4.2.2.2 and 4.2.2.3 for testing, however, these are not Netgear owned DNS addresses. You'll have to contact your ISP for a permanent DNS alternative.

Excuse me, but have I reached the DUMBEST tech support in the ENTIRE WORLD?

FIX YOUR FIRMWARE. THERE IS A FLAW IN IT''S DNS CODE. CUSTOMERS SHOULD *NOT* HAVE TO MANUALLY CONFIGURE THEIR COMPUTERS FOR *ANY* DNS SERVERS, AS YOUR ROUTER IS SUPPOSED TO FULLY TAKE CARE OF THIS FOR THEM. IT SHOULD *NOT* MATTER IF THE CUSTOMERS ISP IS BLOCKING DNS REQUESTS IN ANY WAY, OTHER THAN IF THE ISP IS BLOCK *ALL* DNS REQUESTS, EVEN TO THEIR OWN SERVERS. AN ISP THAT DID THAT WOULD HAVE *NO* CUSTOMERS.

Now, this entire thread is going on my web site. For your information, Google does, or at least has in the past, indexed my site. This means anyone that does a web search will find this "support" thread and go look for SOMEBODY ELSE''S ROUTER. No customer is going to buy a product where the tech support says "if our product is broke, then don''t use it they for what we meant it to do". And while that''s not a direct quote, that IS *EXACTLY* what you IDIOTS are saying.
