There is something inconsistent here.
The Airport Utility still shows that I am not connected to internet, orange/amber light for internet and flashing orange/amber light for time capsule.
If there is no internet connection then this cannot happen.
I also try it on my ipods, iphones and ipads and they all cannot connect to the internet through wifi but when I connect the LAN to my computer it works perfectly.
By working perfectly I assume you mean internet is working.
So the issue is exclusively the wireless??
Let me suggest you redo the setup.. but this time use SMB compatible names.. this helps no end.
SMB names are short, no spaces, pure alphanumeric.
I would also lock the wireless channel so that it doesn't switch automatically.. set to , 1, 6 or 11 on 2.4ghz.. try each in turn.
If you still have issues tell us and we can make more suggestions.
Do you btw still have the buffalo turned on?? I would turn it off when trying to setup wireless.
And do all setups via ethernet only.
Thanks for replying to me so fast.
I cannot connect to the internet even if I connect the cable to my Macbook pro. From system preference-->network, they all shown that I am connect to both wifi and ethernet but I still cannot connect to internet. So I think this problem is not exclusively wireless problem, which I found it frustrating.
Also, my time capsule is no longer falshing orange/amber light now, its working now after I connect it to the Buffalo router. So the airport utility is now showing Internet(Orange/Amber) and Time Capsule(Green).
About the smb, how do I set them? Sorry I am not so good with this.
I did not use my Buffalo while setting these things up, I use it after I found out that I cannot connect to the internet with my time capsule.
Thanks for replying to me.
There is some extra info I need.
What modem.. make and model..?? What kind of broadband?
How is the Buffalo setup? Is it router or bridged and if router is it using pppoe?
There is nothing wrong with keeping the buffalo .. it is a very reasonable router.. and just use the TC in bridge plugged into it..
I have to confess I really dislike the airport utility v6 in Mountain Lion.. it is a kiddie toy version of the real v5 utility. Half your problems relate to the near to useless nature of the utility.
Can you install 5.6 and then we can get somewhere.
Here is howto..
How to load 5.6 into ML.
1. Download 5.6 for Lion.
Click to open the dmg but do not attempt to install the pkg.. it won't work anyway.
2. Download and install unpkg.
Run unpkg on the desktop.. it is very simple.. drag the AirPortUtility56.pkg file over to unpkg.. and it will create a new directory of the same name on the desktop.. drill down.. applications utilities .. there lo and behold is Airport utility 5.6 .. drag it to your main utilities directory or just run it from current location.
You cannot uninstall 6.1 so don't try.. and you cannot or should not run them both at the same time.. so just ignore the toyland version.. the plastic hammer.. and start using 5.6.. a real tool.
