Wifi network created with a Comcast Modem/wifi hub

Can airport express be used to extend a wifi network created with a Comcast Modem/wifi hub?

Apple tells us that the AirPort Express will only "extend" a wireless network...using wireless only...if it is used with another Apple router.
So, it would be extremely unlikely that this would work with your Comcast modem/router.

Configuring my Time Capsule with a Comcast modem

Configuring my Time Capsule with a Comcast modem. I had an outage and the time capusule had a pop up that said change something, I did, didn't fix the problem, but now I can't get wireless networking, but the MacPro connected by ethernet works fine.

Redo the setup.. press and hold the reset for about 10sec and redo it.
This time set wireless using simple name, no space and pure alphanumeric.
Lock the wireless channels as that also helps.
Wireless on an old Gen1 can get pretty tired.

My Mac Mini (Mid 2011) doesn't connect to Time Capsule in 5GHz Network. This WiFi Network don't appear in the WiFi list. What's Wrong?

Oh yes, & 5 GHz doesn't do walls very well at all.
GHz and Network Range
The higher the frequency of a wireless signal, the shorter its range. Thus, 2.4 GHz networks cover a substantially larger range than 5 GHz wireless networks. In particular, the higher frequency wireless signals of 5 GHz networks do not penetrate solid objects nearly as well as do 2.4 GHz signals, limiting their reach inside homes.

Time Capsule & Airport with a new modem WiFi

I have a MacBook Pro and a Time Capsule with Airport. I have a new modem from my Comcast Internet provider that has WiFi Built into it. If I use the modem for my WiFi, will my Time Capsule connect with my MacBook through the modem Wifi? And how can I know which Wifi will be the stronger?

Plug the TC into the new modem with a decent length ethernet cord.. a few meters..
Then simply setup roaming network.. so both the TC and the new modem will reinforce each other.. the setup is easy.. Bob at least says it is.. automagically from the new v6 utility.. but it is not hard to do manually either IMHO.
The basic rule is simple.
TC in bridge.
TC creates a wireless network. Same SSID.. ie wireless name Same security .. ie WPA2 AES = WPA2 Personal.. same password.
Voila there it is. although using different channels can be helpful.. if you run into problem.
Now you don't have to worry about which is stronger.. the MB will connect to whichever is stronger.. without human intervention.
Ask Bob to elaborate..

BTW the roaming network document is a help.

The fact that you have one apple and one non-apple router here makes no difference except in terminology.

Modify/delete a wifi network created in Time Capsule.

Hello, I created some wifi networks with Time Capsule. Now I want to eliminate some of them in order to keep only 2 or 3 "on air"; how can I do it? My Airport Utility is updated; v. 6.3.2

You cannot create multiple wifi networks.. you can create 2.. one for 2.4ghz and one for 5ghz. (Guest network I guess is also possible).. once you change the name of the network the previous ones no longer exist.
If you have a long list of wireless names in your computer.. delete them from your computer. They are simply history and no longer current.
Tesserax has info for deleting all the old names that are stored on your computer to fix connection after wake from sleep issues.

Windows Vista and WiFi networking problem with MackBook Air

Hi, everyone!
Thanks in advance for the following help.
For some specific programms I need Windows Vista to be set up on my MacBook Air.
The problem with Broadcom WiFi adapter.
While moving large files over home network it hangs and looses the wifi network. It works OK while surfing the internet or doing other low traffic job. But when it comes to 2 MB/sec transfer it doesn't work. I tried two different routers, no positive result. PC works propely on any file sizes. After booting the Leopard the problem goes away. So it is onle Windows Vista problem.
May be drivers? I tried 4.170.25.19 Windows Vista drivers from Broadcom - it didn't help. But I am not goog in driver settings in Control Panel, so may be the solution is there.
Any ideas how to solve it?
Thanks for help in advance.
Andrey.

Hello Nescom. Welcome to the Apple Discussions!
I'm afraid I really don't have an answer for you but I can offer my experiences with large files transfer with Vista. My current home network is a combination of Windows PC, Windows Servers, and Macs. Large file transfers between most of them have relatively the same performance, except when transferring large files from the Vista PC to any other OS. It is demonstrably slower. Interestingly, transfers between Vista machines does not appear to be a problem. I understand that this is a known problem by Microsoft and was supposed to be fixed with Vista SP1.
So the problem might not be your network, but Vista itself. I'm curious if you have this problem when transferring large files to another Vista device?

Share Imac's wifi network connection with iphone

Now I have a problem that is contrary to all I have seen so far. My Imac is often with me in places where I can have wifi network if I declare my MAC address in advance. When I am there, I often want to have network on my Iphone as well, but cannot share that connection because wifi is already used for getting into the net. How can I do access the internet from my Iphone (example: skype or Viber calls from abroad to home) in such situations?

Sorry for:
being so late (I had lost the pointer to this discussion due to a massive change in my machinery)
havig written iMac instead of MacbookPro. I was writing my post from my iMac at home...
However, I do know that every device has got a unique MAC address, and I do know the MAC address of my iPhone. My iPhone is connected to my home Wifi network, which allows access only to devices known by their MAC address.
My problem was that I only got ONE MAC address to declare, eventhough I had two devices. So, I could not directly connect my iPhone to that network, but I could connect my MacBookPro (because I needed the network to resume documents during meeting, and so on). I just wanted my iPhone being able to access the network, even if tethered to my MacBookPro (or, even better, without connecting it physically), but I was not able to do that. I can imagine that from my MacBook I could share the Internet connection via Bluetooth, and I tried that way, but there was no way to couple the iPhone on the Bluetooth connection to do anything significant. Also with the physical connection (cable), I did not see any way to share my network access on my MacBook.
I hope I was clear this time..

Having difficulty connecting to 'The Cloud' public WiFi network (UK) with iPhone 5?

Is anyone else having difficulty connecting to 'The Cloud' public WiFi network in the UK with iPhone 5? (It's the free WiFi network for Caffe Nero, Pizza Express, Phones 4U, and Ambassador Theatre Group amongst others. It's run by BSkyB and is also available to Sky broadband customers)
WiFi works fine everywhere else (so it's not an iOS 6 problem, and I am running 6.0.2) but attempting to connect to "_TheCloud" gets instant 'Unable to connect to network' message. Going to Settings>WiFi>_TheCloud reveals that all the fields (IP Address, Subnet Mask etc) are blank.
It used to work fine on my 3GS, and also works on a colleague's 4S. However both my and my boss's iPhone 5's get the 'Unable to connect..." message.
Anyone know how to solve this problem? Or has anyone else even had this problem? There seems to be little reporting of it online.
I've tried emailing The Cloud, but have yet to receive a response.

I found out why there was a problem with The Cloud network I was trying to connect to: The Cloud's equipment at the venue wasn't able to cope with newer devices.This has now been upgraded, and my iPhone 5 connects fine.
Have you tried connecting at different Cloud venues? I discovered that it was a venue problem when I successfully connected to a local Pizza Express's Cloud.

Two WiFi/Networking problems with a T43

Hi. I had a T43 for a few years and loved it but in Sept, it just died. wouldnt turn on. Took out the hard drive.
Just got another T43 (actually 2) and swapped in my HDD. both had the same problem and I cannot find a fix on the website...
Everything works well on them with my HDD. I have been running programs, etc. and also am on Internet thru a wire, but it has 2 problems..
1. It doesnt show that there is a wifi card (same with the other 'new' one that someone else took and installed their OS on the HDD (XP Pro) and found the wifi card. Nothing shows up in device manager under network cards except the gigabit card and the bluetooth (both work) but NO Wifi. Belarc Advisor doesnt show a WIFI card, My guess is that there is one there but something isnt allowing me to see it.
2. In Device Manager, there is one item that has the yellow question mark, it is the "Network Controller" I went to the Lenovo website and also googled it, and cant find a driver for any such device. I am wondering if it has to do with why the WiFi doesnt show up. where can i find the driver and what IS the 'network controller' anyway??
any help would be appreciated. I love the T43 and need it to get working fully asap.
THANKS
Solved!
Go to Solution.

That's weird...
Just in case that someone had swapped the card in the past, try this:

Then go into C>Drivers>Win>Wlanath and run the setup file from there.

WiFi Network Name with Underscore Special Characters Issue

Turns out that iPod Touch doesn't like wireless network names with special characters (e.g. underscores) in them (I had 2 underscores in mine).
It will establish a connection, get an IP address, even use WEP but won't talk to the Internet if the wireless access point name has an underscore in it. If you can change your wireless network name to remove the special characters the iPod Touch becomes very and will connect using the Internet.

I'm looking for a way to escape all characters (not only the minus sign) except for a specific character. Kind of like 'unescaping' a specific character (the '%' sign) within braces {}What about if you apply a function like regexp_replace to escape all known "specific characters", and then unescape the particular specific character again back as e.g. in
SQL> select 'a.da-df%df*' str, replace (
                                               regexp_replace (
                                                    'a.da-df%df*',
                                                    '([[:punct:]])',
                                                    '\\\1'
                                               str2
from dual
STR         STR2
a.da-df%df* a\.da\-df%df\*
1 row selected.i.e. don't escape with curly brackets but with the backslash character.
You can then use this string in your query like in
WHERE CONTAINS(r.POI_NAME, '<query> <textquery grammar="context"> <progression><seq>'
||'aaab'
||'</seq><seq>'
||'aaa\-b'
||'%</seq></progression> </textquery> </query> ' ,1)> 2

Using TimeCapsule with a Comcast modem AND Airport Express. Way slower after updates! What's up?

I've been running this set up for two years now without a hitch. Comcast Modem to TimeCapsule by Ethernet. Then TimeCapsule to Airport Express via WiFi. It used to work great because my TC was far away from my family room and the AE extended my network flawlessly.
After Mavericks and IOS 7.06 installations on my devices (iMac, Macbook Air, iPhone, and iPad) my wifi seems to be moving at half speed. I've rebooted the Comcast Modem and TimeCapsule. I guess I should reboot airport express as well. But I doubt thats the problem. I was thinking of asking Comcast to change out Modems but this is a new problem only since updates. What should I do?
Any ideas?
Thanks
Marylyn

Power off the entire network.....all devices....computers, printers, modem, TC, mobile devices, etc
Wait a few minutes
Start the modem first, and let it run a few minutes by itself
Start the TC next and let it run a full minute
Keep starting devices one a time about a minute apart until the entire network is powered back up
Check the network

WIFI problems solved with D-Link USB WIFI adapter...

I have a brand new Macbook Air and I have persistent problems connecting to my home wifi network. Sometimes I can connect to the router but not the internet, but usually Airport won't connect at all: it keeps asking me for the password for our home network (even though it's stored), so I re-enter the password, but it still can't connect. When it gets to this point I know that I either have to live without internet for the rest of the day, or disrupt my work and everyone else in the household by rebooting my computer and reseting the router (sometimes just one of these actions will work, but it's unpredictable).
So I bought a D-Link DWA-125 USB wireless adapter and installed drivers from Ralink (http://www.ralinktech.com/support.php?s=3) and it pretty much solves the issue.
I don't know what further proof Apple needs that this is a problem with the Air and not the internet/router/etc. It's rather comical that I have to use an ugly old USB adapter to get a brand new Macbook Air to connect to internet in my own home.

I've had my Macbook for 2 yrs and the wifi basically never worked - only when I'm right next to the router, at school, or of course the Apple Store. I tried to get apple to fix it under AppleCare, but since it was working perfectly in the store, they said there was nothing they could do.
If your Mac works well at school, or the Apple Store but not at home, the problem definetly is not the Mac and therefore there is no need to buy a external usb wifi device.
You better will fix the settings of your home router and after that your Mac will be fast and smooth on your home wifi.
I've had only on very rare situations a problem with d-link routers over the years and think (if not damaged) even your d-link will work pretty good with your Mac.
Would you be so kind and explain the settings of your home router and what model it is?

I can't backup to iCloud over my wifi network but I can over other wifi networks

Several days ago, I noticed that I am no longer able to backup my iPhone 5 over my wifi network. It tries to backup for a while and then says "The last backup was unable to be completed." I figured it was a bug with iOS 6 so didn't really worry about it. Then I was at my girlfriend's house and was able to backup my phone to iCloud over her wifi network. Does anyone know why I can backup on hers but not mine? Also strange that I was able to backup on my network at first and then suddenly stopped being able to. Thanks for your help!

I am having the same issue, mine stoipped working on October 4th. I am running mountain lion and I phone 5. I do not know what the issue is at all. Have a brand new macbook pro retina 15. Not sure what the issue is but I hope someone can help us both.

Home Wifi Network Issue using Airport and 2 BT Hub...

I'm having problems getting my home network set up without IP conflicts. Any advice much appreciated...
Here's what I've currently got:
BT Broadband Unlimted
Hub 2.0 connected to broadband line - wireless network switched off
Apple Airport Time Capsule connected to Hub 2.0 by WAN cable (Airport running in Bridge mode)
Various Apple devices (MBP, iMac, iPhones, iPads, iPod), PS3 and Sony Surround Sound connected to Airport with wifi.
Wifi extender connected to Airport by wifi (obviously) for upstairs - PS3 and occassionally MBP connected to that)
Ethernet cable from Airport to a Hub 1.5 in the Garden Office with MBP and HP Printer then connected to Hub 1.5 with wifi.
HDD connected to Airport with USB cable.
Everything was working fine until I ran the ethernet cable to the office and connected the Hub 1.5. It worked fine in the office, wifi connected, I could see the internet and the Airport and the connected HDD.
However, at this point, the iMac back in the house, which connects to the Airport wifi network, sometimes connects to the internet, sometimes doesn't. It connected to the Wifi fine, just won't connect to the Internet. It was stopping at the Hub2.0 "Default Gateway" (according to traceroute). Switching wifi networks on the iMac (e.g. Airport 2.5Ghz to Airport 5GHz, or Airport to FON or Airport to the Office Wifi) fixes the internet connection problem, until next time I try to connect.
This only affects the iMac. The MBPs, iPhones etc have no problems connecting to wither wifi or the Internet...
I figured it must be an IP addressing problem due to the Hub1.5 conflicting with the IP address range configured for the Hub2.0, so I tried to re-configure this on the Hub1.5 in the Office.
However, to get to the Hub Manager, I had to disconnect the Ehternet cable (otherwise it just went to the Hub2.0 Hub Manager). Once I did this and reset the Hub1.5 to factory settings, I could see the Hub1.5 Manager. However, if I click on Advanced and enter the password (after restting it with the SN) I can't see any of the advances menu options in the left hand panel (e.g. IP Addresses). So I can't change the IP address range.
Any ideas how I can get to see the IP Address options on the Hub1.5?
I also tried setting a static IP address on the iMAC, but it won't let me - just says IP address already in use when I try to change it to one in the range set on the Hub2.
Worse thing is, now that I've reset the Hub1.5, the Internet connection keeps dropping on that as well now. It works fine for a few minutes then drops and I have to turn wifi off and on again, or disconnect and reconnect the ethernet cable to get the Internet to connect again, then it drops after a few minutes.
So, I've gone from the iMac not working to the iMac and the office hub1.5 not working properly, and all I've really done is reset the hub1.5 to factory settings...
Shall I just get rid of the 1.5 and buy a different wifi router for the office?
Should I be able to change the IP address range on the 1.5?
Any other ideas?
Any help much appreciated. Thanks in advance.

Have you tried running the TC not in bridge mode?
In airport utility, instead of selecting bridge mode, select share a public ip address. You will get an advisory warning from the TC but just opt to ignore it.
This way all of the DHCP is handled by the TC and the HH1.5 and none by the HH2.
Otherwise a replacement for the HH1.5 might be called for - perhaps and airport extreme.

Possible wifi conflict between airport and dsl modem wifi

I want add my TC to my wifi system. The existing wifi is based on a frontier modem connected to a DSL line. Will the existing wifi or the airport be the functioning wifi?

Either or both.. it is up to you.
Set one to channel 1 and set the other to channel 11. Then both can work happily together.. although I would space them a couple of meters.
