Roaming Network with Powerline Adapter

Hello,
I have read numerous posts on this, but I am still having a small issue. My setup is as follows:
Arris router set on bridge connected to
latest gen. time capsule (set to DHCP, create network), connected to a powerline adapter that then runs upstairs. The other powerline adapter is upstairs and connected to latest generation airport express (bridge mode, create network with same ID and pwd as the time capsule).
Previously, I had the time capsule and the airport express (via the powerline adapter) each connected to the arris router, but this was causing some issues.
Nevertheless, with the new roaming network setup, the powerline adapter seems to be getting slower speeds or the upstairs airport express is slow. I can get close to 30 down from the time capsule, but half that on the airport express.
Any suggestions?

Powerline is always "iffy". The system can work OK when the powerline adapters are on the same electrical circuit, but things really slow down.....dramatically, in some cases.....when the adapters are on different electrical circuits, since there is a significant signal loss when one tries to "jump"' circuits.....no matter what the advertising or sales guy might say.
The signal will also slow down quite rapidly over distance.
Not much that you can do about that, unfortunately, other than experiment a bit with different AC sockets in different locations to see if one might be better than another. Like wireless, powerline is half science and half voodoo, so there are never any clear cut rules about what will and will not work.
Some users can get by with powerline, but the folks who are looking for the best performance almost always come to realize that there is nothing better than an Ethernet cable with no loss up to 300+ feet or 100 meters. Yes, I know that the running the cable might not be easy, but a good electrician or wire guy can do some amazing things.

Roaming network with AirPort Extreme and Netgear R6300

Hi there everyone
I need to know if I can make a roaming network with my apple AirPort Extreme as the base station and then I want to use an Ethernet cable to connect to a Netgear R6300 which will be located at the other end of my house where th connection is poor via wireless.
So is this possible with this set up and if so how do I go about configuring each router to make it work?
Will I need to make both SSIDs the same so I wan wander through the house and stay connected to the same network?

Do not even bother to link wirelessly.. Apple do not allow it.. nor probably does the netgear.. there is no proper standard to wireless link routers.. it is a case where everyone does what is right in their own eyes.
Roaming is the best anyway..
SSID = Wireless Name must be the same.. and use short, no spaces and pure alphanumeric names.. not apple type. You can set a different name for 5ghz.. imho that is the best idea.. but up to you .. roaming and band swapping at the same time leads to chaos.
WPA2 Personal = WPA2 AES security and is the only standard that should be used now..
Password for wireless the same. 10-20 character mix upper and lower case + numbers.. keep it pure alphanumeric.
And now the tricky one.. channels.. there is only one difference between the different wireless stations and that is channels. You can leave everything at auto.. but if it leads to trouble fix them on both 2.4ghz and 5ghz.
Use non-overlapping .. see
http://en.wikipedia.org/wiki/List_of_WLAN_channels
Which show the 2.4ghz channels very clearly.. you will need to work your way around the 5ghz a bit because it differs so much region to region.

TV causes interference with powerline adapter

I just had infinity installed and I have a problem with my powerline adapters, which is next to the TV (it is for the sky+ box for sky go). The powerline adapters are TP-Link tl-pa211 and the TV is a Panasonic th-37px70b.
When the TV is on, the maximum I can get through the ethernet powerline is 14mb/s, but if the TV is off or on standby I can get close 40mb/s (i.e. the maximum on the broadband line). The TV is on a wall bracket so it is difficult to move.
I have tried:
TV in room 1 connected to socket in room 1 and powerline in room 1 - 14mb/s when tv is on, 40mb/s when tv is off/standby.
TV in room 1 connected to socket in room 1 and powerline in room 2 - 40mb/s constantly.
TV in room 1 connected to socket in room 2 and powerline in room 2 - 40mb/s constantly.
TV in room 1 connected to socket in room 2 and powerline in room 1 - 14mb/s when tv is on, 40mb/s when tv is off/standby.
It seems it is the actual TV that is directly causing the interference with the powerline adapater, not the TV causing interference in the electricity line. I'm not sure how it can interfere directly.
Has anyone had anything like this before or is the TV just faulty?

Thanks for you reply. I have tried the TV connected directly to the socket and the powerline connected to a seperate twin socket about 1 meter away and I still get the problem when the TV is on. Also, I have connected the TV to a power socket on the other side of the house with a extension cord while not actually moving the TV and the powerline adapter connected to a socket near the TV and this still gives the same problem when the TV is on. And then, with the TV still on the extension cord to the otherside of the house, I connected the powerline to the same twin socket as the extension cord and this produced no problems.
So, it must be the physical proximity of the TV with the powerline adapter that is causing the problem. So could the TV be emmitting some frequency that is interfering with the powerline adapter?
I actually use a wireless powerline adapter (TP-Link TL-WPA281) in the socket, but for testing this problem I use the non-wireless version (TP-Link TK-PA211). And according to this thread, the BT Hub 3B isn't compatible with wireless extenders. Why is upgrading to infinity so annoying?

HT4260 Can an Airport Extreme be used to form a roaming network with Time Capsule?

I tried the on-line instructions above to extend my Wi-Fi network with a roaming network but the graphics in the instrucions apparently show an earlier version of Airport Utility. Following the intent of the instructions, e.g., ethernet cable connection ports, etc., all I have achieved is a yellow flashing light on Airport Extreme. Airport Extreme has been reset to factory settings but it is not seen by the network.
Do I have it backward, for example, should the Airport Extreme be the base station and the TIme Capsule be the extended station?
What do you think I am doing wrong? Or, is this an impossible extension?
Thanks, Chad

Suggest that you use the much more functional and useful AirPort Utility 5.6 for Mac OS X Lion which was released at the same time as AirPort Utility 6.0.
Keep both 5.6 and 6.0 on your Mac and use the one that you want.
Post back if you need more assistance.

Qemu - Bridged networking with wireless adapter

How can I use bridged networking with wireless on Qemu virtual machine? With virtualbox it can be easily done. I don't why in Qemu it is so complicated, maybe virtualbox have completely difference mechacnism on this. I've read the wiki, it looks like impossible to use wireless for bridged networking. If it is really impossible, why virtualbox can do it?
And, in arch wiki's qemu manual, i didn't see how to use NetworkManager there to do bridged networking. Since, I use NetworkManager and disable the others (like netct and dhcpcd), it make it even more complicated. But, maybe it's because me that don't understand. Maybe someone experienced here can give me a way around this?

bagol wrote:How can I use bridged networking
It's up to you to set up the bridged network - or use TAP, e.g.:
ip tuntap add dev <devname> mode tap user <youruser>
ip lin set <devname> up
ip route ...
... and proxy_arp
... and iptables forwarding & masquerade
It's a good learning experience, to set up the network yourself, rather than have VirtualBox do similar things by *magic*

Internet cuts out for 30 secs with powerline adapter PLSK400

I recently just bought a powerline starter kit (PLSK 400) and I plugged one adapter into the router and into the electrical socket. (which is up stairs). I plugged in my other adapter downstairs in my room and it is hooked up to my PC and Playstation.
The only problem is that my internet cuts out every 20 mins for about 30 secs. This gets annoying cause I play games a lot on my desktop. Any reason why this may be happening?

Hi paperstreet, to change channels you will have to access the PLW400 setup page first.

Configuring Airport Express as Roaming Network from a Time Capsule via Powerline Adapters

I am having an issue configuring an Airport Express to extend my WiFi network as a roaming network via powerline adapters. I have configured as other threads have advised
Open AirPort Utility - Select the AirPort Express - Manual Setup
Click the Wireless tab below the icons
Wireless Mode = Create a wireless network
Wireless Network Name = Same name as the TC network
No check mark is needed next to "Allow this network to be extended"
Radio Mode = 802.11n (802.11 b/g compatible)
Channel = Automatic
Wireless Security = Same exact setting as the TC
Wireless Password = Same password as the TC network
Confirm Password
Click the Internet icon, then click the Internet Connection tab
Connect Using = Ethernet
Connection Sharing = Off (Bridge Mode)
Update to save setings and allow 40-45 seconds for the Express to restart
The only difference is I cannot see an option under Connect Using for Ethernet here there is only the usual DHCP etc
After configuring my Apple TV can see the network and says it establishes an internet connection but Home Sharing does not show my iTunes library but will connect to internet radio.
I cannot get any other WiFi device to connect to the Airport Express but they can see it. The TC and Airport Express have been updated to latest firmware.
Any advice appreciated.

Please download and install AirPort Utility 5.6 for Mac OS X Lion
You can have both 6.0 and 5.6 on your Mac and choose the version that you want to use.
6.0 is interesting to look at, but 5.6 has much more functionality.

Is there a known conflict between an extreme g base station and express n in a roaming network?

I have an extreme g base station connected to a cable modem, an express g connected to a linksys switch via ethernet, and an express n connected to the same switch via Ethernet. The switch is connected to the extreme g base station by Ethernet as well. They are all set up to be a roaming network with 128 bit WEP security. I made two changes to the network recently. I went from a WDS setup with the extreme g and express g, which was generally stable but slow, to the roaming setup above, and I added the express n. Now something is causing the network to loose connectivity at least once a day, requiring a restart of the extreme g. My hunch is the express n is causing problems for the older g units.
Does anyone know if this is a known problem and if there is a solution?
Thanks.

For what its worth.....
I have mixed older "b/g" and newer "n" devices in "extended" and "roaming" networks for years, and have never experienced any issues with this type of setup.
As a Community Support "regular", I can say that I cannot recall having seen the type of issue that you have described, but other users may comment with different opinions.

Question about upgrading HW in an existing roaming network...

I have a roaming network with the following configuration:
First Generation AirPort Extreme (i.e., first square model) acting as the base station connected to my DSL modem. I have a First Generation Airport Express connected to the Extreme via cable acting as a roaming network. This Express extends my network as a roaming network and also provides wireless printing. I also have another First Generation Airport Express joining the same WiFi network (i.e., with the Extreme) to run AirTunes.
For years, this has worked just fine. However, my Express (set up as a roaming network) keeps needing to be reset once a week (by unplugging and plugging back in). I have tried everything to correct this rather new problem. I suspect that it is either interference, the Express is now faulty, or (long shot) my MacBook Pro which is really old is causing some interruption with the Express (it loses it connection a couple times a week, yet all my other Macs don't. And, it had its first Kernel Panic last week). I am getting a new MBP any day as it needed to be updated anyway.
So I am wondering if I can swap out the Express (i.e., the one in roaming) with a new Extreme. I'd like to set up the Extreme in N-mode (something I have not been able to do with my current Extreme since I had b/g Expresses. I would also like to move to 5 Ghz to help minimize interference. That said, do I need to also replace the Express that is used for AirTunes to allow N-mode and 5 GHz??? Or, could I connect the older Express to my Extreme via cable and have AirTunes, while running a 5 GHz N-mode WiFi?
Also, I understand the new Extremes simultaneously run at 2.4 GHz and 5 GHz. Does that mean I am running two WiFis or one WiFi being broadcase on two frequencies? I would want to enjoy 5 GHz, but still have my iPhone connect to the WiFi.

As you are aware, your iPhone will not connect to a 5GHz network and neither will your old Express...
I don't see any need to update this unit as this time if you are just streaming music using Airplay...
However, if you want to spend the money, you could buy a new Airport Express to replace the older "g" version.
I'm sure others here will have other ideas...
If I were to do this set up (i.e., have the old Extreme replace the old Express, and have the new Extreme be the new base station), would the old "AirTunes" Express be able to join the new Extreme simultaneous 2.4/5GHz network because it is connecting to it vis-a-vis 2.4 GHz? In other words, this would elimate the need to directly plug the old "AirTunes" Express directly into the new Extreme... correct?
Also, I assume that the new Extreme (via USB) can do the wireless printing like I currently use the old roaming Express for. Is that right?

Wireless networking with an iBook G3

I'm having trouble connecting to the internet using an Asus WL-167G USB2.0 WLAN Adapter. The other computers on our network are Windows XP and our router is a Belkin wireless-G. I'm also new to Macs which doesn't help. Any help would be much appreciated.

Hi, Fiona. Welcome to Apple Discussions.
Part of the problem may be that an iBook G3 is equipped with USB 1.1. While most USB 2.0 devices are backwards-compatible with USB 1.1, it may be that the USB 1.1 connection is simply not fast enough to support wireless networking with your adapter.
I recommend the original AirPort card for wireless networking with a G3 iBook, even though they are becoming scarce (and expensive). They are the easiest and best solution.

Max IPs in a DHCP range for Roaming network?

Setting up an AirPort roaming network comprised of a dozen or so AirPort-Extremes all connected via a Fast Ethernet backbone.
The Master base station has a Public IP on it's WAN side and is Set to 'Share a Public IP address' and DHCP - but it seems no matter which network prefix I choose for the LAN side, I can not create a DHCP range larger than a single Class C. Is there a way to give out more than 254 IPs? Or can you have a single roaming network with multiple base stations set to DHCP?

Is there a way to give out more than 254 IPs?
No, as the "main" router, providing DHCP server service is the limiting factor here.
Or can you have a single roaming network with multiple base stations set to DHCP?
This may be possible, but NOT with the Apple routers. When configured as bridges, as required for a roaming network, both their NAT & DHCP services are disabled.

Can I use two different frequencies on a roaming network?

I have a roaming network with a first generation Airport Extreme (i.e., first square model), with a first generation Airport Express connected via cable to make up the roaming network. This is for a detached office that is about 50 feet and several walls away. It has worked wonderfully for years until recently.
I believe I am now experiencing some interference to the Express. Basically once a week I have to unplug the Express, count to 10-15, and plug it back in. Then all is well... for about another week. Oddly, the Express light stays green (why if no internet??). Interestingly when I had my iPhone with me (office is primarily used for my MBP), it could still see the Express' SSID. However, like the MBP, its wifi "fan" icon is not able to show a signal.
I have tried changing the channel to one that isn't being used by my neighbors, nor my Extreme. For a while, I was also experiencing interference on the Extreme. But that seems to have been resolved after I changed the channel on that unit. I noticed that my all my neighbors run in 2.4Ghz. So I'm wondering if I should buy a new Express that can run in 5Ghz. But that means I lose wifi connection to my iPhone. I can live with that inconvenience in the detached office, but not in my home (i.e., where the Extreme is).
So my question is: In my roaming network, can I have my Extreme run in 2.4Ghz (to allow iPhone wifi connection) and my Express in 5Ghz?
Side question: I noticed in Airport Utility that my Extreme's frequency is updated (Manual Setup > Base Station > Options) is updated weekly. Could that be somehow causing my Express to stop having a wifi signal and require the Express rebooting (i.e., unplugging)?

So my question is: In my roaming network, can I have my Extreme run in 2.4Ghz (to allow iPhone wifi connection) and my Express in 5Ghz?
Yes
Thanks. Good to know!
Update Frequency specifies how often the Express will check to see if any updates are available...which would have nothing to do with losing the Wi-Fi signal or other problem.
Thx. I feel like an idiot!
Btw, two other questions, if I may:
1. If there is no wifi signal, why would the Express light still be green?
2. When there is interference, why would the Express need to be rebooted? Why wouldn't it simply regain it's connection once the interference subsided? The reason I as is that I have exprerienced interference with the Extreme before and there is no wifi signal. After a minute or two, it would reestablish internet connectivity on its own (i.e., without me unplugging and re-plugging it).

Sky Hub (SR101) configured to roaming network on Airport Extreme?

Hi,
Im trying to find out if it is possible to connect a Sky SR101 Hub to a Airport Extreme to create a roaming network with 3 Airport Extremes?
If so is the procedure of connecting it as follows:
1. Sky Hub ethernet port connected to WAN port of 1st Airport Extreme
2. Ethernet Cable from the 1st Airport LAN port to the WAN port of 2nd Airport (in another room)
3. Ethernet Cable from the 2nd Airport LAN port to the WAN port of 3rd Airport (in another room)
What is the best way for the DHCP?
Do I set the 1st Airport that is connected to the Sky Hub do the DHCP and turn the Sky Hub wireless and DHCP off?
I am a bit confused when it comes to the DHCP side.
Thanks for your help in advance.

The Sky SR101 is a modem/router that provides both DHCP and NAT service.
So, in a "roaming network" configuration, each one of the AirPort Extremes would be configured to "create a wireless network" using the exact same wireless network name, same security setting and same wireless password as the Sky modem/router. Each AirPort must also be configured to operate in Bridge Mode.
Here, I am assuming that the Sky SR101 will be creating a wireless signal. Optionally, you could turn off the wireless on the Sky modem/router and use it only as a wired router if you prefer. In this case, the 3 AirPorts would be providing your wireless network.
1. Sky Hub ethernet port connected to WAN port of 1st Airport Extreme
2. Ethernet Cable from the 1st Airport LAN port to the WAN port of 2nd Airport (in another room)
3. Ethernet Cable from the 2nd Airport LAN port to the WAN port of 3rd Airport (in another room)
This will work, but better wiring practice.....if possible.....would be to connect each AirPort directly back to one of the Ethernet LAN <-> ports on the Sky modem/router. This is called "home run" wiring.
The reason for this is that your proposed setup makes use of what is known as a "daisy chain" configuration.
While the "daisy chain" type of setup will work....if everything is working.....let's say that you configure the network as proposed in 1), 2), and 3) above.
If the 1st AirPort Exteme has a problem, it will take out AirPort Extreme 2 and AirPort Extreme 3 as well. Or, if AirPort Exteme 2 has a problem, it will take out AirPort Extreme 3 as well.
With the suggested method of connecting each AirPort directly to the Sky modem/router in a "home run" wiring configuration, you might have a future problem develop with any given AirPort, but this will not affect the operation of the other AirPorts.
As far as DHCP and NAT service, it might be possible to configure the Sky SR101 to operate only as a modem with DHCP and NAT functions disabled.
But, even if you can do this, your service provider may not support this type of setup, so you would want to check with Sky first to see 1) If this is possible, 2) How to do it, and 3) Verify that they will support that type of configuration.
If you decide to go this route, then AirPort Extreme 1 would be configured to provide DHCP and NAT service. AirPort Exteme 2 and AirPort Extreme 3 would still both be configured in Bridge Mode. In this case, you would connect AirPort Exteme 2 and AirPort Extreme 3 directly to AirPort Extreme 1.

Number of supported users(clients) in Roaming network setup

Hi,
We are planning to configure Roaming Network with 10 units of Aiport Expresses in our office. I just want know how many number of clients can connect to this network.

In theory 50.. https://www.apple.com/au/airport-express/specs/
In reality.. about 10 per unit.. but you might stretch it to 20 if you use both bands carefully. Remember you only have 100mbit ethernet connection.. at absolute max you are going to reduce 10 clients down to 10mbit.. and 20 clients to 5mbit.. that is very slow when you start moving files. And wireless just ain't that efficient.. so much less is better.
You might also find running 10 units harder than you might think unless they are 100M apart.. wireless provides 3 non-overlapping channels at 2.4ghz and about 3 times that number at 5ghz depending on location in the world.
If they are too close to each other.. you will have chaos.
Airport Express is a home unit.. for office you should buy pro grade gear.

Serious packet loss creating roaming network over Ethernet.

Comcast Business Gateway modem/router with static addressing provides one address for an externally accessible web/mail server on one of its four RJ45 LAN ports. The second RJ45 LAN port provides a second external address with NAT & DHCP to an internal private 10.1.10.x network connected to a 24-port Netgear gigabit switch. The Netgear is our home's primary switch, with most of the ports going to different jacks thrpughout our house. We have various PCs and Macs, a home server and other similar devices hardwired through the house jacks back to the Netgear receiving DHCP assignments from the Comcast router.
We've had (1) Airport Extreme base station (last generation, not the tall one) connected to the network, also receiving a DHCP IP address from the Comcast box. It's set to bridging mode, cabled from its WAN port by CAT5e to the Netgear switch and offering a Wi-Fi SSID with WPA2 PSK. NAT/DHCP etc is disabled. IPv6 is set to link-local only. No disks attached. Wireless channels set to Automatically.
At this point we have fairly smooth network performance, everything connects immediately (iOS devices, Android devices, utility boxes, computers, etc) and 0% apparent packet loss.
We have some weak Wi-Fi coverage on the far side of the house and I'd like to establish a roaming network, with a new Airport Express (most recent gen) plugged into a wall jack on that side of the house, cabled by Ehternet back to the Netgear, and set up identically. Same SSID and PSK. But when I activate this, I'm finding the network gets anywhere from 88% to 98% packet loss pinging the Comcast router and going outbound. And none of the iOS devices I tried could establish a functional network connection.
I tried replacing the Airport Express with another similar Airport Express, to same effect. I set the Airport Express to create a second SSID and that seemed to work OK, but then I had two distinct networks instead of a roaming network. I also tried disabling DHCP on the Comcast router and enabling it on the Airport Extreme Base Station, but still had the same packet loss. I also tried setting one, the other, and then both Airport boxes to static addressess bypassing the DHCP for their LAN-side connections (although still bridging) and still too much packet loss. No matter what I do, I can't seem to establish a functional Ethernet-connected roaming network with both Airport boxes.
Any ideas?

Thank you for the reply. The Netgear switch I'm using is a GS724T -- it has management features which I'm working through, but all the ports are set to auto-negotiate and the port the Airport Express is on is lit for 100baseT. I didn't see any way to set the MTU in the Airport Utility menus/buttons.
When I join the Airport Express to the network, it sets up the roaming network as intended. But then performance all across the switch goes downhill -- even when pinging from a PC attached to one of the switch ports to the Comcast router I get 90% packet loss or worse, so that nothing seems to get out or in until I disconnect the Airport Express.. It's that dramatic a difference. It doesn't make sense to me that a wireles roaming network across the two Airport boxes should kill performance through the router...
