PDASync over wireless LAN or WAN

Hi,
Is it possible to use PDASync over wireless LAN (using 802.11b
card/attachment from Palm or Handspring device) or wireless WAN (CDPD or
CDMA modem)?
I know that currently it is used via the serial port on a Solaris
workstation for sync ... but interested to do the same over a wireless
network ..
Any info will be helpful ...
Thanks,
Sailen

Thanks for the reply.
I think that is the solution I was looking at. I think the WAN-LAN was 192.168.2.1, but I will be setting up a CAT5 from room to room between routers.
Ok. I guess here lies my confusion from what I read, as well as my utter lack of knowledge plaing its part.
If I disconnect the WRT600 from my desktop and hook up the WRT54G (with no other connections to the interenet), how do I set the IP without first resetting the webinterface logon from the WRT600 to the WRT54G. If I just logon as normal, it will be, and is, the WRT600 webinterface with all the WRT600 advanced settings. (I did use the same username for both routers. Could that be the issue?)
Or is my thinking incorrect, which it might be, in that the webinterface login, currently set to the WRT600, and currently displaying all the settings for the WRT600, is supposed to change when I connect the WRT54G. It does not, when logging in as normal.
This is where I think I read about resetting the router preferences to allow for the 'admin' logon to be reset to what would be the WRT54G preferences, which are different, but would allow for changing the DHCP and IP.
Possibly my issue is How. How do I get back to the WRT54G webinterface to make these changes?
If I go to 192.168.1.1, as stated already, it will be the WRT600 logon.
Thanks

Voice over IP Roaming problems between 2 Wireless Lan Controllers.

Hello,
we have problems with Voice over IP roaming between 2 Wireless Lan Controllers, this problem is not always happening. I have attached the detailed configuration. We are using LWAPP 1242 & WLC 2106 Controllers.
The phones they are using are Siemens Enterprise optiPoint WL2.
Is there maybe something wrong with the configuration our can I try some different settings?
Regards,
Jordy Broekhuizen

When a wireless client associates and authenticates to a WLC, it places an entry for that client in its client database. This entry includes the MAC and IP addresses of the client, security context and associations, quality of service (QoS) contexts, the WLAN, and the associated LAP. When a client roams to another LAP associated to the same WLC, it just updates the client database with the new LAP information so that the data can be forwarded appropriately to the client. When a client roams to a LAP associated with a different WLC, either in same or different subnets, it sends the information in the client database to the new WLC. This helps client to retain its IP address across roams and maintain uninterrupted TCP sessions. For more information on roaming in the WLC environment.

Satellite A60: Wireless LAN switch at the side is cover over

hi I have a Satellite A60 notebook, I want to turn on my Wireless Lan But the switch at the side is cover over like its just for show. I have all the indications that i can turn it on, the symbol at the fron and the on/ off at the side, but as i said it is covered over and not a switch as showld be. Does theis mean I can't have a wireless connection or is it a fault in the notebook? please help.
many thanks

I do not have an answer, I just want to share your frustration. I recently sorted out a wireless hub for home but I can not get on it with my A60.
I also have the light at the front and the blanked off switch on the right and a manual which talks of wireless LANS in glowing tones.
I was lead to believe that it was wireless enabled but it is not!!!
It even comes up with a graphic "searching for a wireless connection" but that's pointless if it has not got the stuff to work [when it's inches from the wireless hub].

ACS 5.4 with DACL over wireless and wired network

Hi my name is Ivan, I have a question
I have a deployment in my network wired at this way:
Profile 1: corporate's users are working with 802.1X to authenticate computers and users with eap peap mschap v2 and Mac Filtering configuring in the Cisco WLC. My ACS 5.4 is integrate to the Active Directory.
Profile 2: Telephonies IP authenticate with MAB. All the Mac Address are registered in to the ACS locally.
Profile 3: user guest authenticate with portal web from Cisco Wireless Lan Controller over the wired network, and the account exist in to the WLC Lobby Ambassador
A my deployment in the wireless network is in this way:
Flex Connect with central authentication and local switching to connect 15 sites over the wan network.
SSID 1: users corporate working with 802.1X to authenticate users with peap mschap v2 and Mac Filtering configuring in the Cisco WLC. My ACS 5.4 is integrate to Active Directory.
SSID 2: users guest working with portal web from Cisco Wireless Lan Controller over the wireless network, and the account exist in to the WLC Lobby Ambassador.
I would like to configure in the Cisco ACS 5.4 Downloadable Access List (DACL) to use in my network wired and wireless.
How can I do it to my scenary?
Please could you help me?
Regards
Ivan.

Hello. To avoid confusion, let's divide the WLC based upon the operating system.
There are WLCs who run AirOS. That includes WLC 4400, but also includes WLC 5500.
There are WLCs who run IOS-XE. That includes the new Catalyst 3850-X and WLC 5700. (also I think can run AirOS too).
IOS-XE fully support DACL. On the other hand AirOS support DACL partially.
From ACS point of view, when you configure DACL for IOS you configure not only the name of the access-list, but also the access-list entries. That way the IOS devices don't need to have the ACLs pre-configured. This is great because you only need to create and update the access-list entries from only one place (which is ACS) and deploy easily to hundreds of switches.
On the other hand, when ACS configures DACL for AirOS it can only specify the name of the access-list. The AirOS device needs to configure the access-list with a name exactly as configured on the ACS. Sadly, each AirOS device also needs to configure all acess-list entries.
It seems you want to configure DACL along with other attributes. If you explain me a little more your requirement I can show you what to configure.
Best regards

Image processing over wireless

Hi,
One of our subsidaries has a setup where continuous video stream is generated from certain application servers processing real time image processing.
The setup goes this way; 3 PC's which run these image processing & are connected to a 3750G switch.
This switch is uplinked to an access point which then carries all these over wireless to the image processing main server.
About two weeks ago, when they tested this ,all 3 PC's had issues running together when operators viewed/worked upon the images on them.
When either one or two of them is turned off, the rest works fine with no disturbance( intermediate stop & start of images ).
Please help with suggestions on what could be the cause. I suspect bandwidth, but since this doesn't cover any WAN links, i doubt that bandwidth is actually the problem.
Thanks in advance.

It depends. QoS will help if your having congestion on the wired side. WMM QoS will help for over the air. I would look at the switch port and see if you see drops on both the map and rap side. You might just be over utilizing the backhaul. Remember that it is half duplex link so that can be an issue also. I had an install with regular AP's and 3gb video uploads within 30 minutes and the only way to achieve that is only allowing 4-5 clients per AP. the testing you have done seems to show that the max you can do over that link is 2. How much other traffic is using the wireless. Maybe try to isolate those traffic on a separate RAP/MAP pair using AP Groups.

[solved] Troubleshoot ssh with keys (works from LAN, not WAN)

I'm trying to set up ssh so that I can connect to my work computer from home. It is pretty much essential that I keep the work box as secure as possible at all times. (So I can't disable the firewall, come home and test it because IT would not be at all happy.)
I'm not sure if this is an Arch question, a Fedora question or a general Linux/networking question.
The work box is running Fedora 17. It has a firewall eerily like the "simple stateful firewall" described on Arch's wiki. It is running sshd. Public key authentication is enabled. No other form of authentication is enabled. It has a rule allowing ssh connections.
My laptop is running Arch. It has a firewall very like that described on the "simple stateful firewall" page. It has a couple of rules allowing stuff I need at home (printer and something I had to enable for the LAN).
Initially, I was given an internal ip address. I got this working fine i.e. I could ssh into the box from my laptop while sitting next to it in my office over the LAN. I'm using the default form of key pair generated on Arch (i.e. rsa) and am using gpg-agent with ssh support in lieu of ssh-agent to manage keys. Pin entry is using the qt front end as I'm on KDE. (I adapted KDE's config so that it starts gpg-agent with ssh support for the session so that I didn't end up with two instances.)
Once the firewall was in place and sshd was running, they gave me a public ip address. At this point, no port was opened in their firewall to allow WAN connections but I tested the public ip address from within the LAN and it once again worked fine.
Once I'd confirmed the machine could connect out after getting a public ip, they arranged for the port to be opened for ssh. However, I cannot connect to the machine from home.
$ ssh -vvi .ssh/id_rsa [email protected]
OpenSSH_6.1p1, OpenSSL 1.0.1c 10 May 2012

debug1: connect to address xxx.xxx.xxx.x port nn: Connection timed out
ssh: connect to host xxx.xxx.xxx.x port nn: Connection timed out
xxx.xxx.xxx.x is the public ip (works fine from LAN)
nn is the port number
username is my user name (same on both machines)
The options for the host from ssh_config are:
AddressFamily inet
Compression yes
ControlMaster auto
ControlPath ~/.ssh/socket-%r@%h:%p
and the only generic option applied to all hosts is just a line to insist on protocol 2 which I think is default now anyway but I followed the wiki and specified it to be sure.
What have I missed? My networking knowledge is pretty basic at best. (I got this far using Arch's wiki, Fedora's documentation and a little trial and error. That seemed to work well but now I've added google and still can't figure it out. All the hits I get concern cases where the LAN connection works but authentication fails over WAN. But I'm not getting that far - it looks like my work box doesn't respond at all...)
Last edited by cfr (2012-09-25 22:12:06)

So I discovered I'd also managed to kill off LAN access as well as the machine's ability to use any sort of DNS... (I did say it needed to be secure...)
Anyway, I fixed that, reestablished working ssh from LAN but still can't get it to work from WAN.
Question: if ShieldsUp! reports the port as stealthed does that mean that the port has not actually been opened? So the campus firewall is blocking the connection? Because if so, I'm knocking my head against a brick (fire)wall to no purpose whatsoever...
I figure it can't be the software firewall else I'd not be able to connect on the LAN. And it is a public ip address so there's no NAT translation required...

Remote System Explorer on a Wireless LAN

On a wireless LAN when I use Remote System Explorer, it knocks our Fieldpoint network modules off-line. We are unable to ping them. Once we restart the units, they work fine until someone uses the Remote System Explorer again. Any ideas?

We have FP1600s and FP2015s. It only affects certain FP1600s. Firmware revision is 3.0 on the 1600s. Some older ones are not affected and some newer ones are. We configure them in the shop on a LAN, then move them to a field environment. The only firewall is point of entry onto the post.
When using Remote System Explorer (the latest and greatest version), one at a time is "knocked off line". Every time Remote System Explorer refreshes another 1600 is knocked off line. I see no relevance to a crossover cable. This occurs over a WLAN. If we don't use Remote System Explorer then they just chug along fine.
I have used the FP1600 Diagnostic Utility which was a mistake. Now the status LEDs blinks red 7 times.

WRT54G. Computer sees network but can't connect over wireless

So I have a WRT54G router since a couple of years now. Laptop (Win7 64bit), ipod, ipad, phones can connect to it without a problem, but new computer (Win7 64bit) can't. I can connect the PC via ethernet without a problem though.
I powercycled my devices, I changed broadcasting options off and then back on, changed my security mode, tried the MAC Cloning (after doing the MAC Cloning, I lost internet connectivity even through ethernet), resetted my security settings, changed SSID, I'm broadcasting through channel 11 2.462. I also tried deleting the HomeGroup
Important fact: the network is in the list of available wireless network, but Signal Strength is No Signal and I can't connect to it.
My network adapter is ASUS 802.11n Wireless LAN Card, drivers are up to date.
I've upgraded to the latest router firmware.
I use a cable ISP.
I've been looking at everyone else's posts with similar problem but none of the suggestions fixed my problem. Anyone has an idea? I'm no techie so I may be missing something important/obvious...   Thanks a lot for replies (please don't hijack!)

As the concern is with your wireless connection and you have updated the firmware of the Router so once reset and reconfigure the Router... Since you are using Cable Connection refer the link for the configuration: http://www6.nohold.net/Cisco2/ukp.aspx?pid=93&vw=1&articleid=3686
As far as the wireless is concern make the channel to 6, 9 and 11...
Under Advanced Wireless Settings change Beacon Interval to 75, Fragmentation Threshold to 2306, RTS Threshold to 2307...

Wireless Lan Controller Issue

Hi All,
We have a Wireless Lan Controller 4402 with software version 4.0.155.5. On Friday we experience a problem where our clients wouldn't get redirected to the internal webpage for authentication. It would just come up with page not found. We know the page was working fine becasue we could manually type in the
https://1.1.1.1/login.html and the
page would come up and you could login successfully. The users who were already connected to the controller were not affected and continued to operate. We have 2 other WLC's at the same software revision and they were not affected so I don't think it has anything to to with software level. Its like the webserver in the wlc failed to work. We failed over the AP's to the 3rd WLC and rebooted WLC1. After the WLC1 restarted we failed one of the previous non-working AP's back to it and it works again.
I know "now" there is debug commands to run at the time when the WLC wasn't working, but unfortunately I didn't know at the time. The WLC is running again fine and I was wondering if anybody has seen this issue before.
Any ideas on a fix or reason would be greatly appreciated.
Thanks,

We are running WiSM 4.1.185.0 and we just had the similar problem with one controller. The other three controllers were fine when it happened. The exactly issue was the nslookup failed(timed out) from the client, so the web login page won't show when people lunch the browser. A reboot of the controller fixed the problem. We have been running Cisco LWAPP for more than a year (from 4.0.155.5 to 4.1.185.0) and it is the first time we see this problem. TAC is still investigating the cause.

User names from Wireless LAN Controller

Hi all
I'm trying to get a report out of a Cisco 4402 Wireless LAN controller, showing all the current clients on a particular WLAN profile, with their user name.
The Monitor -> Clients screen shows me all the MAC addreses, and I can filter by WLAN Profile Name to home in on the clients I'm interested in. When I click on a MAC address for more detail, I can see the correctly populated User Name on the Client Properties screen - so the WLC definitely knows all the detail I need...
Ideally I want spreadheet with a list of usernames of currently connected users (or even better, users that have connected over a time period). I can't see any way to export this data without doing it manually (and I have 270ish clients at any one time).
I've tried at the command line, with a "show clients summary", which at least gives me a table I can copy and paste into a spreadsheet, but again the username detail is only displayed with a "show clients detail MACADDRESS" - and the MACADDRESS field won't take a wildcard.
I've also tried examining the log files, and setting up SysLog to a syslog server - but I haven't observed user names in any of the logs I've seen.
The WLC is on version 4.2.176.0 - and doing an upgrade isn't very convenient at present - although I might consider taking the pain if a later release provides the funcationaility I need.
Does anyone have any ideas on this one?
Thanks!

Dear Scott,
I have some points to get clarified for step by step approach that has to be carried out during our downtime, or which is best option for this migration.
Is that the WLC running different code will be able to join Mobility Group. i.e. irrespective of Model and Code ?
1. Do i have to create a mobility group and include the existing WLC and new 3 numbers of WLC , thus when i remove the Existing WLC from the Group the Ap will try to get assosiated with other WLC in the group.
2. In WCS changing the Access point template configuring primary, secondary , tertiary Wireless LAN controller with New wireless LAN controller, during the down time this activity will be performed.
Which method or way to proceed during the downtime. Looking for your expert view.
Thanks .... Arun

Internet sharing over wireless

Didn't see anyone post this but is anyone else having problems with Internet Sharing over wireless?
Trying to have the macbook connect to the iMac over wireless and use the iMac's wired internet connection. On the iMac, the Airport card is on, and in network preferences, internet sharing is turned on. However, the options for sharing over wireless is grayed out and I can't get into those options to customize it. On the macbook, it doesn't see it in the available networks list to connect.
Am I missing something? Do I need to "create a network" on the imac now? I didn't have to do this in 10.4.10

After much consternation and countless trials I finally have everything back up and working. Here is what I did finally to get it to work. (Note that I am not a network configuration expert - I am only reporting exactly how I have it configured and it works without complaint).
1. I trashed my \Library\Preferences\System Preferences folder and restarted my Mac since I had updated from 10.4 and I wanted to start from a fresh set of preferences. ( I backed up that folder separately)
2. I opened the Network Preference pane and configured my Ethernet connection (connected to my external AirPort Express which I am using as a wireless router to my other computers) as follows:
-Configure: Using DHCP
-IP Address: 192.168.0.197
-Subnet Mask: 255.255.255.0
-Router: 192.168.0.1
DNS Server: 192.168.0.1 (grayed out and so I am not sure what this means)
I set these settings by clicking on the Advanced button.
Under the TCP/IP tab I had chosen:
- Configure IPv4: Using DHCP
(This set the IPv4 Address, Subnet mask and Router)
- Configure IPv6: Automatically
3. On the Sharing Preference pane, I configured the following:
-Share your connection from: Novatel Wireless EXPD (because I have a 3G wireless connection; otherwise I would have chosen the standard Internet connection)
-To computers using: "Ethernet"
And then I turned on the Internet Sharing Service and confirmed in the pop-up dialog that I wanted to share my Internet connection.
4. Using Airport Utility, I configured the Airport Express by first clicking the Internet button to show the Internet Connection page and set the following:
- Connect Using: Ethernet
- Configure IPv4: Manually
- IP Address: 192.168.0.179
- Subnet Mask: 255.255.255.0
- Router Address: 192.168.0.1
- DNS Server: 192.168.0.1
- Ethernet Wan Port: Automatic (Default)
- Connection Sharing: Off (Bridge)
I also configured my Base Station and Wireless with names and Passwords.
I then clicked Update in AirPort Utility and after it restarted everything magically worked!
I think that the problem lay with my original IPv4 settings where I had chosen DHCP rather than Manually hoping that everything would automatically be set as it had worked previously. The clue was that on my MacBook Pro I noticed that the DHCP was not enabled when connected to the AirPort Express. Even my iPod Touch is now connected to the Internet!
If anyone can explain all of this I would appreciate it.

Lan and Wan port on Airport express

Hi guys I am wondering if you could help me out with my airport express.
I recently bought an airport express and have it set up as the following:
Router--->ethernet cable in to the Wan of Airport express--->ethernet from Airport Express Lan to computer
This is so that I have hardwired internet to my gaming computer and wifi in my room for all my devices. The problem is, however, next year I will not be in a situation that allows me the same setup. I will be too far away to run an ethernet cable from the router to the airport express. So I have decided I shall use it to join the network wirelessly and relay internet through both the Wan and Lan port (think this is called bridge mode?). I was also intending on connecting an ethernet hub to one of the ports so that I can connect multiple devices, smart tv, macbook, ps3 etc. But having one of the ports exclusively to my gaming pc.
My question is, with both Lan and Wan ports relaying internet to multiple devices, would I see a drop in performance, in particular in regard to my compter? Or is the airport express able to join both the 2.4GHz or 5GHz and relay each connection to a specific lan port?
Unfortunately I am not in a position to test this yet, lacking a 5GHz connection in my halls, so I would appreciate if anyone could help shed some light.
Thank you

is the main router also an apple product? if so, then yes you can extend wirelessly, but if the main router is an apple product, why are you bothering to extend wirelessly at all when the main router's signals should be strong enough?
if the main router is NOT an apple router, then you wil NOT be able to extend it wirelessly period.
in my experience, there are very FEW places you NEED to extend a network wirelessly, and i always recommend against it since there is a big performance decrease.
In the case of a wirelessly extended network, throughput may be reduced to less than 60 percent of that of a single device.

Password Recovery for Wireless Lan controller

Hi, I am new to Wireless Lan Controller.
I just wanted to reset the password for the Controller. Can anybody help me with this. link/procedure anything will be appreciated.
Thanks & Regards,
Jvalin

I think they mean that they can not type "reset system" since they can't log in in the first place.
The key point to be made is that you need to restart the controller. So power it off if you can't login. Then console in to the controller and type "Recover-Config" as the username. This will default the configuration and allow you to start over with a new username/password.
There is no other password "recovery".

Wireless Lan Specialization

I am studying for the Wireless LAN Specialization. I have gone through the on-line web seminars. What I would like to know is how do I judge when I am ready to take the test. Is there anyone out there that can give me a topical list of what is covered on the exam, since Cisco has negleted to do this?

I took the test in the later part of 2001 and at the time there wasn't even a time limit, however, a colleague of mine recently took it and was 'quite surprised' to discover the introduction of the 75 min time limit... I do concur with the the assessment that some of the questions seem to have the wrong recorded answers, as do many of the other people I have spoken to regarding this test, but more worrying was the fact that after failing the test at the first attempt, my colleague decided to sit it again there and then, went through all the preliminary bits and pieces with c/cards and what have you, then started the test to find that the 'timeleft' was about 10 mins (the time left over from the previous test!!) meaning that he had to rush through it and consequently failed a second time with another 35 bucks down the drain... It took a further 2 attempts before it finally decided to let him pass (each subsequent time sitting on a different PC - just in case the thing with the time re-occured), and he did take screenprints of the questions in the subsequent tests order to go through CCO and the training material in an attempt to prove that they were correct, but for the sake of 100 bucks (paid for by the company anyway) the amount of time it would have taken didnt seem worth it, and as you say, as for how you go about registering a complaint, we've absolutely no idea. For anyone thinking of taking the test, I would recommend 1) reading as much as you can on CCO and elsewhere about wireless, and dont just rely on the training material, because I saw a few questions that im quite certain were simply were not covered in it 2) If you fail the first time, change PC before you resit the exam 3) Print your answers, as you may well feel you want to check them when for no apparent reason you find you only get 72%. Oh, and best of luck.

Is this equal to voip over ethernet or not

Sorry for imprecise question ?
My question is for WAN link between two sites, not
local telephony ? How to treat this for calculation as voip on Ethernet, voip on ppp, or what ? Are there any differences in calculating overhead over
