Setting up a mixed g and n network on 1st Extreme + newer Express?

I have a first gen Airport Extreme 802.11n (flat white, first one they made before adding on gigabyte ethernet). It is great for my needs. It goes into a cable modem. The Extreme handles all routing and the rest. The modem is just a modem that, BTW, Comcast forces me to rent because I use their phone service and customers cannot buy a separate “Voip” specific to Comcast for use with a cable modem they already own. So a perfectly good Moto DOCIS 3.x modem I own sits idle…)
Anyhow…
I had a first gen Airport Express (very limited in capability). It died. So I got a new Airport Express 802.11n (flat white) about a year ago. I hooked that up mostly to use on a printer and for travel. I made it part of my main network. It “extends” it but, my house/property is very small. A large Wi-Fi network is not needed but, seemed only option to be on network and print.
Recently, I added yet another device to my Wi-Fi network. A small router for an AV receiver. It was, alas, 802.11g. I also have two other g devices and maybe a third and fourth (I’ll have to check, both I rarely use. One is unplugged as I rarely use it and the other is hooked up to an internet TV that is rarely used).
All of these devices worked great until I turn on my old Mac Mini, which I think is also 802.11g. Before that AV receiver router was added, it was fine. But now, Wi-Fi on it is basically gone. Except, when it isn’t!
For some reason, my network has decided that the Mini should connect via the Express. Since other g’s are on that, I think that is the problem. I don’t see how it happens but, sometimes, it connects with the older Extreme. When that happens, it seems to work great! Note, I did try using just he Express in place of the Extreme hooked up to the cable modem for the entire network but, it could not handle it. The Extreme can.
Since both the Extreme and Express are similar as 802.11n Wi-Fi routers except, the Express says something like revision 1 when I look at it on iOS Airport Utility (is it “better” in some way?) I think the solution is telling the Extreme and Express to only accept certain devices.
How can I tell each router to accept only certain devices? The old Extreme has one way (it seems) of doing this while the Express has another. But neither is precisely what I think I need to do. The settings for this are under the Wireless Options button under the Wireless tab in Airport Utility (latest, OSX). But if you can answer this question with any knowledge, you know that!
I’d just buy a new Extreme which, I think, allows radio signal frequency segregation (or whatever this is called) but, alas, these two Wi-Fi routers work great (except for the Mini) and I’d like to use them until one actually dies.

You still refuse to discuss data versus radio signal.
So, I guess that is that. You have no proof to back up your contention as neither do I.
Granted, from the g device to my Express, it is at g speeds. But, I contend, that once that g radio signal is converted back to data only (now at speed of light) inside the Express, the Express sends that data, via the exclusive “Extended network” connection, to the Extreme, at n speed. It has to as the Extreme will only take n speed.
Sure, it is splitting hairs, if I am right. I am not saying I am. But my idea (before our branch debate on g and n signal versus data upon arrival at the Express) is an interesting way to force old g clients to use only one router. But to force those pesky g clients to use the newer simultaneous dual band Express by setting the Extreme to 5GHz g only was a new solution for me. It worked too. In that case, it is not about minute speed gains or losses but simply letting the g clients have their one party at the Express, which can handle them better when part of an extended network with an older, original Extreme.
It is also far better to just have one Wi-Fi router as, adding Airport routers in an extended network, slows things down 60% or less and requires more "data management overheard", according to Apple*.
It is interesting that they said data management overhead and not radio signal management?
Alternatively, using the “Roaming network” method where the two stations are linked via Ethernet, is an even better option.

Mixing public and private networks on the same switch

Hello Everyone,
I know this may get some security engineers in frenzy but wanted to know if there is a safe way to mix public and private networks on the same switch.
We have many remote offices that we want to add public wifi and a couple of other services that would be completely outside of our internal network. Each office has a 3750 with plenty of open ports. How can I safely create a vlan for public access on these switches which currently have our internal network on. I have read that people are doing this to save on the cost of purchasing a dedicated switch. Some people are using access lists and one person mentioned creating a private vlan for the public network. I looked up private vlan and it seemed bit confusing.
Is this recommended? If not what would be the safest way to do this?
Thanks Everyone

How "safe" is relative. If your running just one VLAN on a switch, that's would be the safest (basically the same as mixing traffic on the same wire - separation is done else where).
If you multiple VLANs on a switch, then you need to determine how likely someone might figure out a way to breach the VLAN barriers. (This isn't so easy on newer switches.) If the VLAN isolation is breeched, then you need to examine what does that imply from a security perspective (for example can someone now inject or receive other VLAN traffic).
For most purposes, I don't see mixing public and private VLANs, alone, on the same switch as much of a risk. More of a concern is what can be reached on either VLAN and how well it's protected.

If I set up separate 2.4 and 5GHz networks on my Airport Extreme base station, is it possible to extend just the 5HGz network?

If I set up separate 2.4 and 5GHz networks on my new Airport Extreme base station, is it possible to extend just the 5HGz network with another AirPorrt Extreme that has duel, but not simultanous, frequencies?

Yes, configure the "extending" AirPort Extreme to connect to the 5 GHz network name when you set it up.
Temporarily, locate the extending AirPort Extreme close to the main Extreme for the setup, then move it to the remote location.
But, be advised that it is not easy to extend 5 GHz using wireless. You will almost need to have line-of-sight between the two AirPorts for this to work.

I want to upgrade my old airport express to the new express. Can I just switch out the old for the new or must I delete the old network first and start from scratch with the new express?

I want to upgrade my old airport express to the new express. Can I just switch out the old for the new or must I delete the old network first and start from scratch with the new express?

It is not necessary to delete your old wireless networks first, but doing so may eliminate confusion. If you wish to do that, open System Preferences > Network, and select Wi-Fi from the left column. Click the Advanced... button, then select your old wireless networks and delete them with the "–" (minus) button. Make sure the "Remember networks this computer has joined" remains checked.
OK then Apply.
This prevents your Mac from searching for your previous network which will no longer exist.
A new Express creates an open wireless network that you must select before you can configure it. It appears in your Wi-Fi menu like this:
Select it. AirPort Utility will load and walk you through its configuration.
Edit: If you are really using OS X 10.5.1 as shown in your profile, the above screenshot is not applicable. Instead, select the network called "Apple network nnnnnn" and then launch AirPort Utility.

Set up a mixed platform wifi sub-network with restricted network access

Hi,
We're considering a Time Capsule for our office, but we've never used one and have a few questions about whether the TC can accomplish what we want to do.
Our office is in a private suite that shares a wifi network with other private suites on the same floor. In our suite we have two immediate needs - a shared private (sub)network backup hard drive and shared network printer(s). We have a mix of OSX and Windows computers that will be on our suite's network.
*Here's what we'd like to try:*
1) Connect the Time Capsule to the wired LAN on our office floor's network.
2) Connect our computers to the office floor's network, wirelessly through the Time Capsule.
3) Connect our printer(s) to the Time Capsule for wireless printing.
*Additonally we want to:*
1) Block other office floor network users from accessing/seeing our office suite's Time Capsule Hard Drive.
2) Block other office floor network users from using/seeing our Time Capsule networked printer.
I know that we could easily connect everything with the Time Capsule and set it up as a separate network. But then we have to move from our suite's wifi to the Time Capsule network every time we want to print or access the TC backup - not ideal.
Any ideas are greatly appreciated!

Never mind. Picked up a TC and got everything worked out and running perfectly.

Network with Airport Extreme, Airport Express and Time Capsule

Hi,
I have a good internet connection working perfectly in the following order. ISP connected by ethernet (cable) to an AE and this extended to an EX and this extended to a new TC. The AE and AX are 801.11 b/g/n but not dual as the new TC. My question is. If I work with an iPhone, the AE is going to work just with g forcing to TC to work with g as well with the rest of the equipments (AppleTV, other iPhones, iMac? I have an iMac that should be connected to the new TC and I would like to do it by 802.11n, is it possible in this configuration? I now that it would better if I organize the network with the new TC (dual) first. However, the TC is too far from the iMac and this is not my favorite option.
Another question is:
The new TC is very close to AppleTV but wirelessly. Will I increase the speed for watching movies which are placed at TC (through external disks connected to the USB in the new TC) if I connect the TC to AppleTV using an ethernet cable?
Thanks,
Jokin

... My question is. If I work with an iPhone, the AE is going to work just with g forcing to TC to work with g as well with the rest of the equipments
The answer is yes, but I believe you can avoid that by having the iPhone connect only to the new dual band TC. Configure *everything else* to run an 802.11n network exclusively - not "802.11n (b/g compatible)". This way the iPhone will be unable to connect to that network, causing it to run in the slower b/g compatible mode. Your iPhone will work fine, as long as it remains within range of your TC's 802.11g wireless network.
Remember that you will need to change all your equipment's settings: the Extreme, the Express, the TC, and maybe the AppleTV.
Galt's rule of networking: "The number of problems you encounter increases exponentially with the number of devices on your network."
So... proceed methodically.
The new TC is very close to AppleTV but wirelessly. Will I increase the speed for watching movies which are placed at TC (through external disks connected to the USB in the new TC) if I connect the TC to AppleTV using an ethernet cable?
The speed will be limited by the slowest link in your network chain. A wired network is always preferable, since it cannot be affected by interference or obstructions.
If you are streaming movies from the Internet, your wireless link will probably be the limiting factor.

MIxed Wifi and Powerline Network with Airport Express

Can anyone help set up a network using both wifi and ethernet?
I currently have a BT Home Hub ADSL router providing wifi throughout my house and 2 airport expresses to stream music from my iMac. The problem is that the sound occasionally drops out. I've tried most of the common fixes from the discussions but nothing seems to work reliably. My next step is to try and use powerline adapters. If possible I want to use the following configs simultaneously:
1. BT Home Hub (Broadband) to wifi throughout the house inc my iMac.
2. IMac to powerline adapter to powerline adapter(s) to airport express(es). I have 3 200Mbps adapters.
Thanks in advance.

Each AirPort Express that is connected to the network using an Ethernet connection should be configured as follows:
Open AirPort Utility - Click Manual Setup
Click the Base Station tab located just below the row of icons
Assign a separate name to each AirPort Express
Assign a device password for each device
Adjust Time Zone settings
Remove the check mark (if present) next to "allow setup over WAN"
Click the Wireless tab
Wireless Mode = Create a wireless network
Wireless Network Name = Same name as your BT wireless network
No check mark needed next to "Allow this network to be extended"
Radio Mode = 802.11n (802.11b/g compatible) a good choice
Channel = Automatic
Wireless Security = Exact same security setting as the BT wireless network. If settings are not exact, the network will not function correctly.
Wireless Password = Same password as the BT wireless network
Confirm Password
Click the Internet icon
Connect Using = Ethernet
Connection Sharing = Off (Bridge Mode)
Update to save settings and allow the AirPort Express to restart
When all Express devices have been configured, power down the entire network....all devices...order is not important
Start the modem/hub first and let it run a few moments by itself
Start each AirPort Express one at a time about a minute apart
Sart each network device the same way until everything is powered back up

Beginner setting up solaris 10 container and having network card problems

Hi I am just learning about solaris containers and am having an issue of getting my new zone to be seen on the network.
I have installed the global zone server name GPSAPP02 network address of 192.168.200.45 works fine.
I created :-
a pool called "ellipse-pool" using pooladm/poolcfg
a zone called "ellipse-zone" using zoneadm/zonecfg
I used the followijng commands...
zoneadm list -cv
zonecfg -z ellipse-zone
create               --
set zonepath=/zfspool/zones/ellipse-zone
set autoboot=true
     add net
set address=192.168.200.46/24
set physical=eri0
set defrouter=192.168.200.254
end
set pool=ellipse-pool
verify
commit
exit
The output from the "zonecfg -z ellipse-zone info" command is below:-
zonename: ellipse-zone
zonepath: /zfspool/zones/ellipse-zone
brand: native
autoboot: true
bootargs:
pool: ellipse-pool
limitpriv:
scheduling-class:
ip-type: shared
inherit-pkg-dir:
dir: /lib
inherit-pkg-dir:
dir: /platform
inherit-pkg-dir:
dir: /sbin
inherit-pkg-dir:
dir: /usr
net:
address: 192.168.200.46/24
physical: eri0
defrouter not specified
I then installed the zone and rebooted using zoneadm.
I can login to the zone and setup the timezone and terminal etc.
I gave this a hostname of GPSEL01 as this is what I want it to be known as on the network.
So far so good but from the network I cannot ping the IP address I assigned to the zone 192.168.200.46
What have I missed or what should I check to troubleshoot this?
I ran a ifconfig -a and received the following information...
ifconfig -a
lo0:1: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
inet 127.0.0.1 netmask ff000000
# ifconfig lo0:1 192.168.200.46 netmask 255.255.255.0 up
ifconfig: SIOCSLIFNETMASK: lo0:1: permission denied

Hi
I notice in your output from ifconfig -a in the global zone that the NIC card is nge1.
However in your zoneconfig you have set the NIC card to eri0 (physical = eri0). I cannot see this NIC card in your ifconfig -a.
When a zones is of IP-type shared-ip it needs to use a network interface that is already plumbed into the global zone. In your case you need to change the NIC in your zone config to nge1 :
zonecfg -z ellipse-zone
select net address=192.168.200.46
set physical=nge1
end
exit
Then reboot your zone.
A couple of other minor comments.
1) As it appears the zone is on the same subnet as the global zone, if the global zone already has the default route of 192.168.200.254 setup you don't need to specify it in the zone config. You are most likely to use the defrouter parameter if the zone was on a different subnet to the global zone (but shared the same physical NIC).
2) You have specified the netmask in the address field which is fine. But again this should not be necessary as long as your /etc/netmasks file is correct in the global zone.
Hope this helps

Does a mixed N and G network make the network slower for the N-enabled?

Hello all,
I was just admiring my Airport Extreme box after registering it, and I noticed this bit of fine print:
"Speed and range will be less if an 802.11a/b/g product joins the network."
Does this mean that my 802.11g printer makes the network slower for my two 802.11n macbooks?

Okay,
For a follow up: I'm using the "guest" network for all my G-level wireless devices, and the regular network from all my N devices.
Does that overcome the mixed network limitations? It seems like it wouldn't - because the Airport is basically creating two virtual networks out of one network. Or are there two individual networks on the Airport?
Thanks!

How to set up an integrated wired and wireless network

I have an iMac 17" 1GHz connected to a ethernet hub which in turn is connected to a DSL modem and from there to my ISP. I also have a MacBook Pro wirelessly connected to an AirPort Express; the AE is connected to the same ethernet hub through its ethernet port.
I can connect to the Internet wirelesly using the MacBook Pro, but I can not seem to connect to the iMac.
How can I keep the iMac wired and the MacBook Pro wireless, but see both on a network? The AE instructions don't seem to have an example for this kind of network.
Any help would be greatly appreciated!
Cheers,
Martin

Martin,
As Frank said, you'll need a router with DHCP and NAT abilities (nearly all have this) connected to the modem.
But just in case your "ethernet hub" is actually a router, just re-configure the AE not to distribute IP addresses - AirPort Admin Utility - Network tab. Try that and let us know.
For minimal clutter, if you were DSL broadband instead of cable, you could sell the modem, sell the ethernet router, sell the Airport Express and buy a single Ethernet and Wireless DSL modem router - for less than the price of the AE. Some people like to keep the modem separate to make upgrades to the modem cheaper. My solution is to buy a decent modem in the first place, ie make sure it has ADSL2+. Almost all modem/routers do this now, even my ancient ones have firmware upgrades to offer this.
For minimal spend, you can pick up an Ethernet router for about $30. Just replace your ethernet hub with it.

Netgear WPN824 on mixed iMac and PC network

I purchased a Netgear WPN824 router for use with a PC laptop and iMac.
My iMac recognised the SSID of the router but on enetering the WEP Hex key I got an error.
The only way I could solve this problem was to switch the router from 'Auto 108' mode to 'b and g' mode. This means I no longer can get a 108Mbps connection with my laptop. The 'Auto 108' mode is supposed to switch between 108, g and b mode automatically so I thought it should work with my PC in 108 mode whilst still making a connection with my iMac but it appears not.
Has anyone got the router working in Auto 108 mode with an iMac or is it just fundamentally incompatable?

Has anyone got the router working in Auto 108 mode with an iMac or is it just fundamentally incompatable?
It is not part of the standard and therefore not supported by Apple. You need to disable it.

Dual N and G Networks with Airport Extreme?

Hey gang-
Was at the office store looking at some current wireless N routers, in particular Linksys. They claim to be able to run wireless G 2.4 gig and wireless N 5 gig networks separately and at the same time. One suggestion was to run home computers on the G network and media servers on the N network.
So, my question is, can the new Airport Extreme run simultaneous dual networks like that as well?
My plan would be to connect an Airport Express running in 5 ghz N bridge mode to my Tivo and keep the G network for the other computers in the house. Does this sound right?
Thanks!
Dave

If I understand you correctly, I can set up my Time Capsule to run as an "N" only connection and extend the network to my Airport Extreme and run that as a "G" connection?
As long as you realize that you will not be "extending" the TC wirelessly with the AirPort Extreme. Instead, you will need to connect the two by Ethernet. To extend it wirelessly, would require setting up a Wireless Distribution System (WDS) between the routers ... which will definitely reduce the available bandwidth and compromise performance.

I set Google as my homepage and every time I open a new window all I get is a blank page, how can I rectify this?

I downloaded firefox 8.01 and as usual I set Google to be my homepage on opening. After doing so I still get a blank page and would like to know how I can rectify this.

i found the solution to my problem:
just click the extensions-button on top of the screen (in dutch it's "extra". Go to "add-ons" and uninstall the veedh-thing-plugin. problem solved :D

Extend both main and guest networks with a 2nd Time Capsule?

I have a 4th generation 2TB Time Capsule set up to broadcast primary and guest networks. I am running out of storage. I would like to increase my storage and I would also like to extend both primary and guest networks.
I currently use an older Linksys router (WRT330N) operating in bridge mode (wired connection to the TC) to extend the primary network, but it does not extend the guest network.
If I purchase a second (5th generation) Time Capsule to replace the Linksys, can it be set up to extend both the primary and guest networks?
From searching the forum, it appears not, but I'd like to confirm. Is true for both both wireless and cabled range extension options?
If I'm not able to extend the guest network this way, I'm inclined to settle for extending the primary network as I currently do and look for other ways to increase my network storage capacity (e.g. by upgrading the drive in my existing TC).

If I purchase a second (5th generation) Time Capsule to replace the Linksys, can it be set up to extend both the primary and guest networks?
Yes, either using wireless or an Ethernet connection between the two Time Capsules, providing that the 4th Gen Time Capsule is running at least firmware version 7.6.3.
A wired Ethernet connection between the two Time Capsules is highly recommended. If you plan to extend using wireless, the second Time Capsule will need to be located where it can receive a very good signal from the first.

I have an wireless printer and a new wifi router. I have set the printer and iPhone / iPad correctly to the new router but when i try to print it won't recognise the air printer. Help. All was working fine on my old router

I Have a new wifi router and have set up my iPad / iPhone and wireless printer correctly to the new router but I can't print from the iPad and iPhone. It keeps saying ' no AirPrint printer found'. Help please!

Start with the most basic thing that you can try. Unplug the router from power for about 30 seconds, and restart the printer and the iPad and plug the router back into power.
