Q: Dropping Wi FI Signal

I dont see how this would resolve the problem.

The problem appears to be between the computer and router, this just changes it from router to internet.

confused.

I think using Google's public DNS bypasses the DCHP process - it eliminates a fair amount of chatter between the router and the Mac, at any rate. This could solve the problem for at least some users -- and it would be a huge clue for Apple's engineers.

*face slap* That's DHCP.

I am not a network expert, but I don't think the DHCP is related to the DNS issue. DHCP assigns your Mac and IP address on your side of the router. DNS resolves the names like "http://www.google.com" into IP address on the other side of the router. Some people have improved the wireless signal dropping issue by assigning static IP addresses to their computers thus turning off the DHCP entirely on their router. You still need a DNS even if you have static IP addresses for your computers. These static IP addresses will address any issue of your Mac not finding an IP address from the DHCP, or losing their DHCP lease when put to sleep. Both have been suspect in this issue, and this is why assigning static IP addresses has been suggested in these threads.

A new DNS server can improve your speed of loading web pages. Google's servers are suppose to be well maintained and fast. Your ISP (like Comcast) might not be keeping their servers well maintained.

But this is just my semi-informed opinion. I could be wrong. I wish a real network guru would get on.

JPDEMERS --

Tell us exactly which model routers (and firmware) don't have this issue with Snow Leopard? I'm sure quite a few users here (me included) would be interested in knowing what works, and what doesn't. And the stranger issue, is why is it 3 macs will work fine with a particular brand router, and the fourth one doesn't?


sheryl -- previous user of 10.6.2 / and downgraded to 10.4.11 until wireless dropping issues get resolved.

that may be difficult as only those with problems will be here.

I don't really know what happen but change the DNS for google one solve my problem with my wireless dropping all the time it worth to try.

Hello Dear!
I had a macbook late 2006 had the same problem so after lots of forums I heard i should upgrade the wireless card from ABG to N so I did nothing change the same issue happen have done the same on my mac mini with one I connect throughout ethernet cable once it not working wireless I sold my macbook and bought a Macbook pro surprise surprise it got the same falls' let once at apple store back with the same problem so left i there once more last week Im waiting still for to came back maybe tomorrow mean time I found this about google DNS on Fawllow Saudimac (How to: google Public DNS on and airport.) So give it a try on my mac mini and it work fine. So router i used to have a netgear abg ( also have the same problem) the upgrade for one netgear Range Max 300 had problem till google DNS. Now I'm waiting for my macbook pro to came back from apple store to if it got the problem still. If it does going to try google DNS on it as well. Soon as I have done it back to you guys with a feed back whats works.

Don't know for sure, but judging from the number of people here, vs. the number of people running Snow Leopard w/o a problem, I'd say the vast majority of routers work just fine. Most people (admittedly, and maddeningly, not all) report that their MBP works fine at work or at school. I suppose it would be wise to avoid those reported in this thread, including Apple's.

Absence of evidence is not evidence of absence. Just because an individual does not send a post to this discussion group, it does not follow that said person is not experiencing the same problem. In fact, only a tiny proportion of users of any device ever bother to post to a user discussion group. All we can conclude from this thread is that a number of users of MBP running SL experience similar problems that were, for the most part, not present prior to upgrading to SL.

We should start a list of names, of people having issues, maybe get it going around the net and see what we can figure out. Maybe get Apples attention somehow?

I dont see Apple doing anything about it, unless it starts to effect there sales and or image.

UPDATE: Since I've turned of IPv6, I've had 4 days without a drop. Will continue to test per my list, but so far, this IPv6 shows some promise.

Apple is almost to launch the build 10.6.3. This build have enhancements (fix?) for AirPort and other areas. I really expect a fix in this update.

That sounds promising.

I have had this problem since I bought my Macbook Pro last June (Wifi signal constantly dropping, having to turn off and on airport to regain connection)

Thankfully, the suggestions of donv (The Ghost) and qUAan on Page 1 of this thread solved the issue for me. I don't know which one did the trick, but it doesn't hurt to do both!

Good luck everyone.
