Q: Wifi Constantly Dropping in Lion

Sandpuppy,

I feel like I have the same issues as what you descirbed. I'm using a macbook late 2007 (macbook3,1). When I updated Lion, all of a sudden my range was lessened greatly (have to be about 3 feet from the wireless hub) and I get disconnected all the time but accessing the assistant in network setting triggers a connection but only for a few moments...

ARG, I say...

Im using a D- Link Router

NO you definetively have not the same issue as your network, computer, configuration and other hardware are not the same.

Maybe it sounds similar but is not.

Which model of the 300 different type's since D-Link start selling routers?

And what hardware else in your network?

DNS is DNS what ever Router you use and if it isnt pushing it to your PC

I was trying to help - Ill leave now Thanks..

PS ... Rugby let me think ... if you are UK based, did you use a BT-DSL Box??

Yes UK Based WALES !

And if you meant to watch the Rugby ?? No I used my Sky Box

No, but Rugby is famous in GB  For that I just guess.

If you indeed use a BT box the DNS problem came from the fact, that the BT Box have preset (not changeable) domain "home" for your private network segment.

Apple use a multicast DNS protocol for local name resolution and for that the "home" will not respond proper cause the BT Box use the Windows method.

http://en.wikipedia.org/wiki/Zeroconf#Apple.27s_protocol:_Multicast_DNS.2FDNS-SD

Windows systems are not so sensible on that, cause Windows adapt automatically (default setting) the routers name resolution method via DHCP regardless of the set "workgroup" in the Windows network settings.

If you switch the Mac's to use "home" instead of "local" and renew the DHCP settings on the Mac, the DNS problem will vanish.

There is a disadvantage in changing the local domain (workgroup) from >local< to >home<. if you want to use Airdrop with Lion or Apple's Bonjour Service (zero conf networking) Lion insist that all systems that want to use  Airdrop have to be in "local".

For that it is sad, that the BT-Box wont let you change the "home" domain.

Thanks for that explanation - Though Im not using a BT-Box Useful for future reference.

But it is looking like my issue was DNS as since adding the DNS servers locally - Im still connected 27 hours later without one drop out

Just to keep in mind ...

It's very unlikely that your ISP does not provide a DNS server via DHCP during connect.

For that you may eventually check your router (your DHCP server) settings about that issue. Eventually also the DNS cache of the router became corrupted or have a problem.

By the way ... I keep my fingers crossed that your boy's will drown the frogs next Saturday .

Of course we will drown them !

My ISP most defiantley does provide DNS, but I prefer to use OpenDNS..

You may check the router for fault's, cause it should (depend on model) normally be possible to set a OpenDNS address in the router and the router should provide that setting to the stations on DHCP.
