Connected as follows:Is your computer plugged directly into the cable modem or do you have a router?
Should mention that the Cisco is dual function - both a modem and a router.
My other option with my husband gone, is to move my iMac into his office so it is sitting next to the Cisco and TC and see if my wi-fi settles down (as his wi-fi seems stable). However, I won't be able to test out AirDrop which is where my problems with wi-fi really manifests itself.
Before my husband packed up his computer for his trip, I moved my iMac to the same desk that the MBP, Cisco, and Time Capsule sit on. No improvement in connectivity performance. No AirDrop.
Can we go back to the beginning.
Is your iMac still next to the Time Capsule ?
Can you try connecting by a cable from the iMac to the TC ? Does that work OK ? Make sure you restart the iMac.
Now try connecting from the iMac to the Cisco. Does that work OK ? Make sure you restart the iMac.
Does the Apple TV work OK ?
Are both the Cisco and the TC operating with WiFi ?
Unplug the LAN cable from the iMac and restart it. Does it connect via WiFi ?
Can you check which unit the iMac is connected to ? Do you know how to do this ?
I agree we should try using the Cisco as a modem only and for this I will wait until hubby gets home. Go ahead, call me a wussy, lol
In the back of my mind has been lurking the dark cloud of a possible re-install of ML in my future.
Yes, the network right next door is as strong as both of ours.
We have an iPhone4 and iPhone3Gs so I assume that would also preclude us from using 5Ghz? But out of curiosity, how do I check what GHz we are using?
I went to System Report for wi-fi but didn't see anything there. What I did see there is that our Cisco and TC are 802.11n, Cisco Channel 6, TC Channel 1. The neighbour who has the strong signal is on 802.11g but also on Channel 6, the same as our Cisco. I'm assuming they probably have the same ISP and Channel 6 is the preferred one for our neighbourhood?
BTW, what's the difference between WPA and WPA2Personal? The neighbour is WEP.
And another thing...The TC network appears in two places 1. Current Network Information and 2. Other Local Wi-Fi Networks with the last two characters of BSSID different. Also, under the Current info the channel is both 149 and 1 whereas under the Other info the channel is only 1. Also Signal/Noise is different between the Current info and the Other info.
1. To check what you are using look at the following :
On your iMac do Alt left click on the Wireless icon in the top right part of your screen (has 3 curved segments and a dot - looks a bit like an ice cream cone). It will reveal what you are connected as (mine says Channel 36 (5Ghz) plus some other stuff). You will also see the SSID name in System Preferences>Network>Wi-Fi>Network Name.
On your IOS units look at Settings>Wi-Fi.
2. Looks like your neighbours's WiFi is interfering with your Cisco. All your WiFi is on 2.4Ghz. There are only 3 frequencies that don't overlap at 2.4Ghz : 1,6,11. I suggest changing the Cisco to Channel 11. There should be a menu select somewhere in the Cisco setup.
3. WEP is Wireless Equivalent Protocol and is the easiest to break into. WPA is better and WPA2-Personal is best. If it is a potential issue for you then go to WPA2 (all mine are on WPA2) and use a strong password with a mixture of characters e.g. (not mine) Qn?9h%1dT* etc for at least 10 characters. I have this for all my On-Line financial logins as well as the iTunes password and WiFi stuff. (To remember it all I have another list file with an ever stronger password that I CAN remember ! - or use something like 1Password)
For more info than you need, look at this : http://en.wikipedia.org/wiki/Wi-Fi_Protected_Access !
4. Your TC is transmitting on 5Ghz (Channel 149) and 2.4Ghz (Channel 1) simultaneously.
You can download a free utility called "iStumbler". When you run it, it shows you all the nearby wireless networks, and what channels they're using
Option+click wifi revealed channel 149 5Ghz for the TC
Re: setting Cisco to channel 11 - I'm going to call our ISP and have them walk me through it on the phone - not confident enough to do this on my own. It will really only be as an experiment for just this week if we are going to bridge the Cisco next week when hubby returns. But in the meantime if I change the channel and move my computer back to my room away from the Cisco and TC and choose the Cisco network it should show if the neighbour also using channel 6 has been contributing to the problem if the Cisco suddenly provides more consistent connectivity.
Any thoughts on the TC showing in both Current and Other info categories in the System Report window? Or is it showing up under Other because it is "current"ly transmitting in 5Ghz and the 2.4Ghz channel is the "other"?
And lastly, I think AirDrop not working is something else entirely (even though it is a wi-fi function) and is probably going to require a reinstall of ML - major anxiety here at the thought of that .
Going into "About this Mac" --> System Report gave me this information.
And yes, your other information confirms what I have already be advised.
Thank you very much for chiming in.
Yes, my AExtreme shows up twice in any WiFi listings - once for each band. I have different SSID names for each band so that I can chose which is preferred for connection.
Yes, you might find that the Cisco now performs OK.
Reinstalling ML is no big deal other than downloading the stuff again. If you are brave, you might try creating a USB installer (google ML USB installer), but I've been unsuccessful so far (operator error).
Have fun tinkering.
Thanks for confirming that double entry for the TC is normal.
I did copy the ML installer onto a bootable USB before installing it but quite frankly, if it needs a clean install I will take it to the "hospital". It is still under AppleCare and the AirDrop issue is an open case with Apple Support.
If changing the Cisco channel and/or bridging the Cisco resolves things, I will post back here just to bring closure to this thread. And if Apple Support resolves the AirDrop issue I will also post that info here for completeness.
Thank you so very much for the time you have dedicated to this!
