Hi,
I have been so disappointment in Apple products, it is just unbelievable. If some body explain to me in what way I'm stupid - I'll it my words. So here is the issue.
I have TC for about year working with my PC as wireless router and home storage. I don't have any complains on this account. When I bring it home, install airport utility set it up - it work perfect. I don't mess to much with configurations just make every thing that the "assistant" ask.
So I have following configurations on it
Radio mode: 802.11n (802.11b/g compatible) - (My PC have only 802.11g wireless)
Channels: Automatic
Wireless security: WPA\WPA2
using DHCP
As I say it work alright so far. But one lucky day I got MacBook in my possessions. I really like the thing all this cool features - elegant stuff beautiful, but IT DOES NOT WORK WITH TIME CAPSULE. or works with in really abnormal way. It connects to network some times, works for while and than drops out, it works more stable when PC is on the net. I have come over several "helpful" hints in forums, such as "time out" failure. This "magic solutions" helps for another half an hour, but that's it. I download iStumbler so two see if some body works in same channels, so there is. And MacBook "use to" lose the connection when some body interferes. So might it be the case? Then why PC don't care? It might be that TC trying to switch between the wireless formats in due course, but then it must be PC to be disconnected. So could any body explain How come PC WORKS BETTER then MacBook with APPLE Time Capsule.
