New Mac owner with recurring wi-fi problems

Hi all!

I've finally taken the plunge and got myself a MacBook Pro in the last week of July - very happy with it, it's already gone on a two week Mediterranean holiday with me and performed very well - the battery life on normal usage is something else!

The one recurring problem I have with it is Wi-Fi connectivity.

I have a BT Homehub 1.5 (s/w version 6.2.6E, 802.11b/g) - not the brand new black one which is draft-n capable - the slightly smaller iteration of the original Homehub. It is WPA-PSK secured.

We have three computers and two consoles in the house that all use this wireless network: a four year old Sony Vaio XP SP3 desktop (my other half's PC), a self built Windows Vista Ultimate PC, a Wii, a PSP and this MacBook.

The MacBook is Bootcamped with XP SP3. Under this OS, the wi-fi connection is rock solid. Under OSX, every two to five minutes or so the AirPort indicator drops away to 1 bar or nothing. If I click on the indicator to force the re-scan, it picks up the connection almsot instantaneously. It doesn't matter where in the house I am with the laptop - the furthest point from the hub or sitting right next to it with nothing between myself and it - the behaviour is the same.

(In fact, as I write this, I have had to click the Airport control several times to maintain the connection)

I have looked through the forums and have tried a couple of the solutions mentioned: manually selecting a channel on the Homehub (9-11 are recommended apparently, but I have tried them all) un-hiding the SSID, manually configuring IPv4 and disabling IPv6 in Network Preferences etc.

The Macbook is in the same workgroup as the other machines under WINS configuration, and I have been able to browse the public folders on the windows machines and vice versa when it is up and running.

What is frustrating is this works so well when it is on - fast and speedy internet access (though I must confess I prefer FF3 to Safari). The problem obviously doesn't lie with the hardware - the perfomance under Bootcamp is proof of that - stupidly fast Wi-Fi, with no drop outs whatsoever. I can only surmise that is therefore a problem to do with OS X?

If it's any help, there is another Homehub network nearby, and another network over the road at a BT place (internal business network, not Openzone). Both are secured, and I'm wondering if their presence is enough to confuse Airport?

Any help that anybody could give me with this would be appreciated.

15.4" MacBook Pro 2.5GHz, Mac OS X (10.5.4)

1, 6, or 11 are recommended not 9-11.

if you have the white BT home hub then this is a thompson router in disguise and are not very good routers. They are same box that my isp (bethere.co.uk) issue branded a bebox.

I had countless issues with it and the only way to get a solid connection was to replace it completely. I now use an apple basestation as my router/access point and zyxel adsl2+ modem and macs and pc's in the house never have and issue with wireless.

Hi, thanks for the suggestion - I've tried it, but the same occurs in g mode. At least n mode gives me stupidly fast networking on the Windows machines.

One interesting thing - if I am within a 2 metre radius of the router, I am more likely to lose the connection - in other words, if I am sat on the other side of the room it seems more stable. I've had it sat next to a working microwave, underneath a flourescent downlight, next to two wall plugs both switched on, with three walls between it and the router, and I lose the connection less often than when I'm right next to it. Now I'm really confused - I presume there is some attenuation of the signal occurring, so either the signal is too strong for the poor MBP in normal usage and it gets swamped, or (more likely) it's trying to drive me insane.

Gibber gibber...

Okay, think things may be settling down with regards to the connection. First of all, if I'm sat in the dining room at the back of the house, I appear to have a rock solid, continuous connection over wi-fi. If I'm in the front room, sitting a bit further away from the router seems to help, but if I use the MBP on the floor, even if it is in direct line of sight, it still drops the connection. I think that the further back I am in my house, the fewer other wi-fi networks from the houses on my close are detected. It may just have been that it was getting flooded with multiple signals.

It still doesn't explain why Windows doesn't care where in the house it is and connects first time every time, but at least I can sit down and get some work done without fear of the connection dropping out at an inopportune time.

I presume it must be the AirPort software built into the MBP. Hunting around on these forums it seems a lot of people started to have wi-fi issues with one of the updates to OS X 10.4 Tiger, back in the autumn of 2007. It also seems that this compromised code has carried forward into Leopard and has not been dealt with properly yet. Over in the MBP > Networking discussion there is a massive thread dealing with this issue.

I hope my experiences help others to figure out their problems!
