I am the Wireless engineer for a large retailer in Michigan and recently we deployed the Cisco 4404 LWAPP controllers at our corporate campus. We support the following clients on our access points 802.11B, 802.11G and we are currently adding 802.11n clients. The problem we are having has to...

Has anyone successfully created a point to point IPSEC vpn tunnel between a linksys BEFSX41 and a Cisco ASA5510 Firewall? I have built many tunnels, and this one has me stumped. I can complete phase 1 with no problem, but phase 2 gets an error even though both devices show the tunnel as...

Each material type will have its on db signal loss. Best thing to do is measure it...exmaple concrete block walls have about 6db of attenuation while drywall has 3...what you could do is measure the RF signal strength with the enclosure open and then with it closed..this should give you a...

Sound slike your wireless profile may have been deleted from your laptop. If you re-create the profile, you should be good to go. Mark C. Greenwood, CNE, CCNA, BICSI II With more than 16 years experience to share.

Wow, a 14 dbi directional antenna for 150' that's a bit overkill. Here is my advice. A maxrad or similar mftr 6.5db gain panel antennal will go about 750 feet roughly. 1 14 dbi gain antenna will go at least a mile or more depdning on transmit power..which may be too far considering you only...

Since you have 2 private networks one on a router side and one a pix side, you need to have rules that allow both through, so inbound rule and outbound rule for the respective interfaces. Then you most likely need to make sure that you do a nonat for the two subnets so that their physical IP...

Is the port your ap is plugging into setup for 802.1q encapsulation I see you have trunking already, but I dont see the 802.1q encapsulation. If it's not this could stop the vlans from working correctly. Mark C. Greenwood, CNE, CCNA, BICSI II With more than 16 years experience to share.

You may want to invest a little more money and get a commercial grade access point and either have it be designed for outdoor use, or put it in a NEMA enclosure. Make sure you also include lightning protection as this is required by the NEC for outdoor RF. You cannot install it without it. As...

Yes it is possible. I have seen this happen where the router gets flaky, that in turn causes the connection from the cable modem to be flaky..until the device finally dies. Time to get a new one. Off the shelf routers are cheap, but they have no way of warning when they are sick and are about...

The clients are all hard wired to the Hilo battery which operates for about 18+ hours before it is changed or re-chrged. So by default we have the CAM mode set. The problem is definitely client related as we did an upgrade to 11.1.1 and for the most part things are much better except a deauth...

I should mention as well that when we use a cisco 350 wireless card, this problem does not occur. Mark C. Greenwood, CNE, CCNA, BICSI II With more than 16 years experience to share.

I have a large distribution warehouse which has about a million square feet of floor space and has a new Cisco 1242 wireless infrastructure in place. The rf environment has good coverage from front to back and has no co-channel interference and operates witha 5.5 to 54 megabit data rate...

We did fix one error, at the boyne router, the IP address has been changed to 10.50.0.24 Mark C. Greenwood, CNE, CCNA, BICSI II With more than 16 years experience to share.

some testing that we performed What we confirmed: 1. We can still get to the internet from the Boyne office via a proxy server at CAH 2. We can remotely telnet to the Boyne router from the CaH router 3. We can ping from the CAH router to the Boyne router 4. A host on the boyne network can...

Oh forgot about that..one day they could get to the internet but not access everything on the remote lan, the following day they could access the remote lan but not the internet which does not make sense because all of the devices both on the bridged LAN and main lan use the 10.50.0.0/16 subnet...

I need some help with this. I provide some consulting for an organization and they have a T1 link configured between two locations. There was a 1601 router at each location and a verilink csu/dsu at each location connecting to a full T1. Each router was setup and configured to bridge the...

Please keep in mind that this tool is stictly for wireless access point placement. You can do a search for Motorola Enterprise Planner on the web and you should be able to get to the link. but in case you need it..here is a link...

I use a software package called enterprise planner by Motorola which helps to plan pre-deployments by predicting ap placement based on the types of usage, number of clients and as part of this you can model the environment, walls, fixtures, etc. and the software will actually calculate the RF...

I actually have cisco tac running this by their engineers. Because they could not figure out why a 515e would do it and the 506 is capable of 25 ipsec lan to lan / client connections and I am no where close to this. I actually have a typo because the other 501 is actually another 506. So 2...
