Syncing over a large network (Specifying access point / channel)

I work at a University where there is a large Campus Area Network, which has many different connection points for the same network (eg. "University Wi-Fi Network")
I connect my macbook to the network, then I connect my iPhone to the network as well, both via Wi-Fi, however I cannot sync from certain apps / use the keynote remote because the iPhone does not see the macbook and vice versa.
Is there a way to specify which channel or access point (i may not even be using the right terminology here) that the iPhone uses to connect? Or is it even possible just to see that information so I can direct my macbook to connect to the same access point that the iPhone is using?
I can often get my computer and my iPhone to see one another when I'm in an older building, but as most of my work is done in a newer building with greater Wi-Fi access, 99% of the time I can't connect one to the other.
Thanks!

Wireless LAN Controller not broadcasting network to Access points

Good Day Team,
I am working with a 2100 series WLC controller and 1100 series access point.
I noticed that the wireless lan controller is working. Also the access point is working.
The issue is that there is no internet connection on the access point.
What could be the error?
Kindly advice

Try do diagnose your problem following this steps:
1) Connect to the wireless network
2) Check your IP address with "ifconfig"
3) Check if your gateway is set correctly with "route -n"
4) Try to ping your gateway. Is it working?
5) Try to ping an internet IP like google: "ping 74.125.234.115"
6) Try to resolve names with "nslookup www.google.com" for example.
7) Try to traceroute to an IP or name on internet. Check the result to see the last hop you reached.
8) If you passed all those tests, try this: "telnet www.google.com 80"
If everything works, but not the test #8, your problem could be related to some proxy configuration.

Problem with creating an Infrastructure Network (via Access Point) for WLS 9163.

Hi,
I am trying to connect the WLS 9163 to an Infrastructure Network (via an Access Point). I have connected it via an Ethernet cable and am using MAX to configure it.
The setting are as below:
Obtain IP Address through: DHCP
Country: US
Radio On: Yes
SSID: wireless (selected from drop down implying the wireless network is detected)
Wireless Mode: Infrastructure
Authentication: Open
After doing these settings, I click on Save Settings. The device reboots itself and takes the IP address, Subnet mask and default Gateway automatically. The WLS link LED on the device is also turned on. The System State is 'Connected' and both the Wired and Wireless Connection Status is shown as 'UP'.
So far so good.
Now if I remove the wired connection and refresh the device, it does not get connected via wireless (which I believe it ideally should). The System State is shown as Disconnected.
I am using a Phoenix Contact WAP and have set the authentication as Open.
Please suggest some solution.

I had this exact same problem and it took me a while to figure out. As strange as this sounds, I figured out that for some reason if I had the WLS-9163 too close to the router and I pulled the wired connection, the wireless connection could drop. I read on a post in a different forum about someone removing their antenna and it working just fine so I tried that and it worked off and on but mostly off. So I figured out that the further distance away I was the better the connection stability was and I got far enough away from the router to where it was a steady solid wireless connection. This sounds really backwards from what it should be and was really bizarre but I tried different routers, used all different types of settings, had the latest firmware and had all of the equipment sitting on my desk and could not get it working once I removed the wired connection. This may not solve your problem but this worked for me so I thought I'd share that info. I was just so shocked to figure out being too close to the router seemed to be screwing my stuff up.

Can't print through wireless hookup. Printer says there is a router/access point channel conflict.

I cannot print. Printer is wirelessly connected to the airport extreme router.
My printer says that the network connection passes all tests but there is a note: "A router/access point channgel conflict has been detected.
The Epson Printer utilitie says only "Communication error". I've tried changing channels to no avail.

I finally figured out how to fix this after a few weeks of being with out my printers. I tried the reboot of everything and it didn't work. I went into the airport utility and start poking around. I tab through all the various setting and everything looked good. By virtue of tabbing the "update" button was active. I hit that and the airport extreme router rebooted and bingo the printer works for all my PCs and MACs. This seem to have started with the last epson update but who knows. Good luck

Access point channel config

hi
I have 5 access points and want to configure channel and its frequencies...
what should be the channel frequency and its operating mode so that user would get bestpossible results??
I am facing some wifi fluctuation problems
I have set frequency channel to auto
operating mode to mixed
channel bandwidth 20
I am using trendnet 638AP
please help

Think of it like a classroom. We'll call the students channel 1.
So when a student is talking, no one else should be talking, so that he/she can say what the need to. Now a step further, if all the children are trying to talk at the same time, no one can hear what anyone else is trying to say, the all interfer with each other.
Now, you have three children, 1(spanish),6(english), and 11(french). Now each of these are speaking to their translator. Because they are different, they can all speak at the same time withouth inteferring with each other.
An odd analogy, but does it make sense?

Syncing over a home network addresses in Addressbook

I've had a lot of trouble setting up iSync to work with .Mac in Tiger, so I'd rather use a home network to synchronizes addresses in Apple's addressbook between machines sharing the same home network. How would I set that up?
I want to be able to preserve the group vCards which have already been established on the addressbooks of three machines, and use just one machine to have all the addresses. But the first step is to get the addresses and vCards which are in common between the three machines centralized on one.
Thank you.

If users are only permitted to log in as "guest" then they will have restricted permissions - generally read-only. If you want the users to have broader priveleges then one way is to create a new account on the computer that will be the server. Assign that account a username and password and set up the degree of access you want to provide. When others on the LAN log into the server have them use the account username and password. That way they will have the privileges assigned to that account.
Another way is to download and install Sharepoints (www.versiontracker.com) and use it to set up sharing and assign user access and privileges.

Problem with PowerBook (but NOT MacBook) and two access points on network

I recently installed a wall-plugged ethernet adapter system (Netgear XE104 and XE103) and plugged a wireless access point (Netgear WPN802) into one of the adapters (in the part of our house where we lacked a wireless signal) in order to extend the range of our (DSL) wireless network. I configured this new access point--disabled DHCP, assigned an IP address to the access point that does not fall into the wireless router's IP adress range, put the wireless router and access point on different channels (6 and 11), and made sure the router and access point had the same SSID.
I have had no problems using the resulting setup with our new MacBook--everything goes as planned. BUT I am having a terrible time with my PowerBook G4. It has a really strong signal everywhere, but when I open my browser it says that I am not connected to the internet. The problem seems to be that my PowerBook refuses to change channels once it connects to one. I installed iStumbler to see if I could manually control which access point/channel the PowerBook uses, and, while I can track the signal strengths for both access points, I can't get my PowerBook to switch from one access point to the other.
I've tried just about everything I can think of. I suppose I could try giving a different SSID to the access point (and then try to switch with the airport menu in the toolbar), but I would like to avoid this if possible.
I would really appreciate any advice you have. Thank you!

Can you connect if you temporarily turn off WEP or WPA?
This will determine if it is a WEP or WPA issue.
Does your PC support WPA, from both a hardware and a software perspective?
The problem you are having probably lies with the encryption key.

Deleting all Access Points (Network/3G/GPRS)

I'm having problems tracing 2 of my mystery access points on my N95.
I've deleted all the network assigned access points Tools > Settings > Connection > Access Points. But when I try to connect using the built-in web browser, there are still 2 Access Points showing.
How can I delete these two? The list of access points are already empty, I even deleted the WLAN connections.
http://www.gameops.net

These are Packet-data (gprs) connections, not WLAN. Check the English manual on page 127 how to delete.

Is there any way I can control which specific access point I connect (and stay connected) to from amongst a set of access points with the same SSID?

I'm working from a boat in a harbor in which the ISP has deployed numerous access points around the periphery. All the access points share the same SSID and each is configured to use either channel 1, 6 or 11. From my location, there are over a dozen of these access points "visible" (based on the the output of WiFi Scanner) with a range of RSSI and S/N values that vary over time.
The ISP has told me that the quality of my connection should be "perfectly fine" for any access point with an RSSI value better than -75, but I know from experience that my connection quality is miserable (i.e. < 50Kbps download) for almost all of these, including those with RSSI values better than -75. There is at least one exception, however, which gives me on the order of 2Mbps download, which is "great" in this context.
I've tried using a more powerful USB antenna plugged into my MacBook Air (mid 2011), but as far as I can tell, it really doesn't make much difference. Neither does my location within the boat. The overriding factor seems to be which access point I happen to connect up to.
I should point out that the closest access points are about 75 yards away, with many of them being several hundred yards away or more. I'm guessing that even though the signal strength of some of the distant access points is causing them to get "chosen" some times, the results are unacceptable due to the distance.
I'm hoping that I can determine, through experimentation, which access point(s) provide(s) acceptable performance and then configure my Mac to limit my connection to those points through whatever mechanism I need to use (e.g. channel, MAC id, etc.).

Establishing a wireless connection with a client computer is left to the access point for various reasons. One reason that your Mac may not connect to the strongest access point is that it may have reached a limit of the number of clients it can serve, leaving it unable to accept a connection with another. The limit may not be very large.
Suppose that happens, and your Mac establishes a connection with a more distant access point having a weaker signal. Then, suppose a client drops off the network. Doesn't this mean your Mac will switch to the stronger access point? Not necessarily. The throughput delivered to and from your Mac would have to drop below a threshold specified in the AP for it to drop the client, leaving your Mac free to connect with another one. The reason for this is to prevent rapid switching from one AP to another in an area in which two signals are of approximately equal quality. If that were to occur the frequent and repetitive handshaking between the two devices would slow throughput to zero.
In an environment in which several access points are broadcasting the same SSID, Apple provides no insight as to how it determines which access point to choose. This is the reason I suspect this "choice" is a function of the router, or access point. The connection originates with it, not the Mac.
Now, what would solve your dilemma would be to determine a way to control the access point with which your Mac connects, by specifying the access point's unique MAC address for example. In this happy circumstance, you could maintain an editable "whitelist" or "blacklist" of the harbor's access points and be able to choose which among them you prefer.
I do not believe OS X maintains such a record of MAC addresses though, only those of the routers it uses. If I am correct about that, such a solution is unlikely to exist. Don't let that discourage you from searching for one though... I would concentrate on something like "selecting access point by specific MAC address".
I did find this patent application though:
Roaming Network Stations Using A Mac Address Identifier To Select New Access Point
Perhaps it's a start

Packet Data Access Point Names vs real data server...

I am trying to activate an application that requires GPRS.
I currently can get EGPRS and assume that will do the same but faster. But I have a question that may not pertain to this but as I am new at this I will ask it here. From reading I see that the settings of packet data appear to have more to do with setting up phone as a modem to use. So I don't know truly if this has any bearing on my problem with the software registering to complete the setup of it.
However my web access which is unlimited month to month internet access which allows me to go anywhere on web (not a walled garden) also uses this GPRS or EDGE version of GPRS. I am in the USA with T-Mobile. Phone is set to use GSM. The screen where it concerns connectivity says that I have Access Points which were configured by T-Mobile sms file they sent me twice. I actually have 5 names under Access Points.
1)MMS = wap.voicestream.com
2)T-Mo WEB = Internet.voicestream2.com with small i in settings
3)T-Mo WEB(01) - this from 2nd sms copy same
4)T-Mobile Internet = Internet.voicestream2.com with small i in settings too.
5)t-zones this is their wall garden = wap.voicestream.com
ok since I can browse the web anywhere and download the application I don't know why I cannot register it. But it states it needs an internet connection before activation through authentication, or basically registering it to use.
So I am trying to do this after verifying that I have an internet connection with the too connection arrows symbols on phone screen showing internet connectivity with E over them currently by starting a browser first as the application doesn't seem to do this for me when trying to activate it.
E
--> where the lines are solid. Ok here is my issue here.
The arrows are not coming up correctly in this forum anyway I get what shows I have EGPRS connectivity, I don't know if the application is sensitive to using GPRS only but will find out. I doubt it. The GPRS would show the arrows with an antennae above. I am talking about the indicators from what the pdf and book say.
Below Access Points on the menu in settings for connection is Packet data.
Packet data has to variables
1) when needed , or when available
2) Access point
Access point is blank. Should I enter one of T-Mobiles names in the list above this under Access Points such as
T-Mobile Internet or should I put the server name in specifically internet2.voicestream.com?
I set the Data Call setting to Unlimited to make sure if its using this process it doesn't turn off after the 5 minute default on the next setting.
Any ideas why this gprs app is not activating itself and making the gprs internet connection with the pin I was provided? I had to use the pin just to download it and install it.

that will work. You only need to change if you need to have always on (highly unlikley) or if you are using modem dial up and need to specify access point for that.
If you using Nokia One Touch access then you don't even need to define access point in this menu as that application will take care of it for you.
All other network aware applications will use access point settings as defined in settings menu.

Can someone post s40 v6 access point wml?

Hi,
i use a nokia c3-01. I cant use email on my nokia as in the commercials suggested because my provider needs proxy settings. For the standardinstalled Internetbrowser i can configure a alternative account but the standard email prog just support wlan or access point. and in the nokia s40 v6 menu there seems to be no possibilty to configure access points with proxy.
Does someone have a wml example for nokia s40 v6 to get access point for the email prog in nokia c3-01 with proxy?
I found a WML-Example for Nokia s40 v5 but the c3-01 does not acceppt and does not show the access point after senden the generated .prov file to the c3-01. If someone needs help how to convert a wml to .prov i can help if needed.
heres the access point with proxy wml example for s40 v5:

I added one access point in settings and my email is working now.
I've done below steps, you could try to modify to your internet access point.
Menu->Settings->Configuration->Personal config. sett.->Options->Add new->Access point Account name: VFNZ internet Access point settings: Data bearer: Packet data Bearer settings: Packet data acc. pt.: www.vodafone.net.nz others keep the default values. Then back to the personal accounts and activate the VFNZ internet from Options.

You'll need a Packet-data connection supported by your provider. Your provider might not allow streaming over their net. Unless you have a unlimited data plan, it's gonna cost you a lot of money. Use WLAN instead.

2 Access Points?

I have a E4200 as well as a WRT54G. I'm looking to create two different access points to the same network, one access point being 802.11g (WRT54G) and the other being 802.11n (E4200) I want to do this because I need the extra speed from 802.11n for streaming video to my consoles. The problem is that there are multiple devices that only reach up to 802.11g.
Would it be possible to plug the WRT54G into the E4200 in order to give a second access point (probably with different SSID) so that 802.11g devices can connect to the network, without having to destroy my 802.11n network? The WRT54G is currently running DD-WRT.

Yes. You can use two access points. davidssw posted the general instructions. I think dd-wrt even supports "bridge mode" which allows you to to connect the internet port of the WRT to your E4200. You could then use all 4 ethernet ports on the WRT for wired devices.
You can use different SSIDs etc. on both. Most important make sure that you assign different non-overlapping channels on both for the 2.4 GHz band. Pick two from 1,6,11. Operate the E4200 on 20 MHz channels only for the 2.4 GHz band.m Don't use the "auto 20/40" setting. A 40 MHz channel on the 2.4 GHz band basically allocates most of the total available 2.4 GHz band and thus you will most definitively interfere with your WRT and the E4200 should eventually automatically switch back to 20 MHz channels anyway. Thus, instead choose 20 MHz and a static channel to avoid this situation.
I would also suggest to use a different SSID for the 5 GHz band on the E4200 and, if possible, use that SSID for streaming. Of course, this depends on your consoles and whether they support the 5 GHz band or not...
