WIfi conectivity problems

I have a Mid 2010 15" MBP (Core i7) as does a colleague and we both have experienced the same symptoms as you. We can connect to our wireless access point and we are on the network fine for 10-15 minutes but then we can no longer access the network or ping any hosts. The connection to the AP appears to be fine when this happens (full bars in the Airport menu). Turning Airport off then back on again brings the connection back again.

Other devices and older MacBook Pros don't have this problem with our AP.

My computer does not exhibit this behavior on other wireless networks which makes me think that it may be some kind of incompatibility with our wireless access point. In our case we are using a Netgear WNDAP350 (firmware is current). If other people experiencing this problem can post their wireless access point models as well maybe we can narrow down the problem.

Read your manual on updating firmware.

I had the same issue with intermittent conection, now mine will not connect at all to WiFi. When my other macs and iPhone can. It is clesrly a fault with the Macs WiFi not the routers. I am on a Netgear Router that works fine with other machine, just not my macbook pro.

That is an older router, seemingly configured in your case to run with even older 802.11b networks , chris (which reviews suggest were poorly dealt with by it at the best of times!).

You should try selecting other channels on the router, just in case you are getting interference from external sources, and you might want to see if it works any better when set to operate in only 802.11g mode, rather than 802.11b/g (though your MBP is really best served by 802.11n, which didn't exist when your router was produced).

You might want to check out the router manufacturer's own forums and support boards to see if there are any hacks available to help it work more effectively with current hardware and software.

Having the same problem on brand new MacBook Pro 2.66 Core i7. Using Netgear WRT54G2 router.

Sorry, I meant Linksys WRT54G2

I'm having the same problem here, using a D-Link AirPlus Xtreme G DI-624 Wireless Router with about the same settings as the original poster has. It's not limited to networking a macbook pro, however, as some of my devices keep losing connection after several minutes while others don't:

- MacBook Pro 2008 (losing connection)
- iPhone 2G (no problems at all)
- iPad (losing connection)
- PS3 (no problems at all)
- Airport Express (losing connection)

same problem here. Works fine for a few minutes, then suddenly i'm not able to ping anything while airport appears to be connected.

same intermittent wireless problem on my macbook pro i7 15".

Connects for a few minutes, then wireless indicator shows full strength but connection is dead. I have to Turn Airport Off, then On again to regain a working connection.

One thing I notice is, this only happens at my work, where we use a cisco? wireless router. At home, when I'm on my Airport Extreme-N, it works fine, never drops.

We use Cisco antennas where I work as well. Also my home router is a Linksys wag120n which is also made by Cisco. But I 've noticed this when connecting to other places too.

My issues appear to have been resolved after the 10.6.4 update. This is the second day that I haven't had any problem at all with wifi
