EnGenius EAG-2408 / Long Range Wi-Fi - Fresnel Calculations?

Dec 8, 2012

i am setting up a network between two houses. I have two Amped Wireless SR300 repeaters and currently I am getting so-so signal strength between the repeaters. To remedy this issue, I purchased two EnGenius EAG-2408 external antenna's.My question is how to calculate how high to mount the antenna. A formula is preferable because I do not know the exact distance off hand and I will have to go out there and measure. I am estimating approximately 75 to 100 yards for the distance. Its flat, with a few trees/brush.

Repeaters:[URL]

-Transmit Power: Up to 20 dBm
-Receiving Sensitivity: -93dBm

Antennas:[URL]
-Omni Directional Antenna
-18 degree vertical beamwidth

Long Range Wifi Through Buildings

Mar 16, 2012

I've recently lost my ability to access the internet at uni and as this is quite an inconvenience I am considering some alternatives, the most viable one I've managed to come up with hinges on the fact that I live in a building which is only a road and another building away from the main uni buildings (3 buildings on 2 city blocks), basically it looks like this: UNI BUILDING 1 | UNI BUILDING 2 |ROAD| UNI BUILDING 3 |ROAD| MY APARTMENT.So I'm thinking of building one of these: url.. or waiting for the r20000g (dual band) to come out and buying that.THEN the area I'm having a bit of trouble with: I need to get reception about 600-700m away through buildings, so I've been looking at Yagi antennas and such but can't seem to find any information on the following:

1. Will a high powered directional antenna go through a few buildings and still make it 1km (.6 miles)

2. How directional is a directional antenna? like if I point one in the general direction of the building how accurate do I have to be? (I have no problem buying 4-5 antennas if I need to)

3. Do I need a new Wi-Fi antenna for my laptops? it seems odd to me that a laptop would be able to transmit back 1km while I need a giant antenna to get to the laptop (I know its not this simple but it still seems odd)

D-Link DGL-4500 - Long Range Wireless Router

Apr 21, 2012

I currently have a D-Link DGL-4500.

I am looking for a more powerful wireless router that has a larger range. I want to have the ability to use the laptop at the house next door, so I need a range of like 150 ft, going through multiple walls (both concrete and wood) and still have enough for general Internet access.

My first question is if it's even possible and if so, what is a good router/system to use.

I would still need the ability to connect Ethernet to the router (at least 4 ports) and the wireless, obviously.

A major benefit as well would be the ability to install something like pfSense or DD-WRT onto for further management.

Cisco Firewall :: ASA5510 VPN Bandwidth Calculations

Mar 14, 2012

Were running an ASA5510 with multiple IPSEC VPN clients over a 100Mb leased line. At the moment we have about 10 active clients however we are looking at gearing up to about 100 clients.Question is, is there a known method for calculating the required bandwidth for this number of clients or indeed obtaining metrics from already connected clients with this calculation. We have tried a few monitoring products, most notably Solar winds, however none of the products we have tried seems to be able to give us the throughput of the individual VPN connections to assist with our calcs....

Cisco WAN :: 6513 / EIGRP Unequal Load Balance Calculations?

May 15, 2012

I have used EIGRP with the variance command for years.  Recently we swapped out our 6513 for 2 Nexus   7K's and lost the variance command.  So now I'm stuck running our two MPLS routers to a 3750 which then connects to the 7K's, so I can get the unequal load balancing back in operation.So because I can't play with it while it's in production I'm using dynamips to simulate the configs.  The problem is I'm not able to get a traffic share count ratio that reflects the actual difference in bandwidth. 
 
The two lines have 155 MB and 45 MB respectively, for a ratio of 3.4.  Now you can't really send ".4" of a packet but the total packet ratios when dividing the traffic share count should be similar.  I'd settle for 3.  I was able to get 2.9 in the past but now on the simulator I can't even get that.  I'm seeing traffic share counts like 120:89 and 120:71 depending on how I fudge the metrics when I inject the routes from BGP.
 
I found this link: [URL] a stellar article by the way, and this guy is doing calculations to arrive at a 5:1. BUT when I apply the same formula using specifics from my network and the desired ratio of 3:1 what I get is an AD so high that the route is no longer feasible.  I simply cannot make a ratio fo 3:1 using the formula. How to be able to make anything other than a marginal ratio actually work or is this all just theoretical?

EnGenius EOC5611P - Transfer Data Between Laptop And SBC Wirelessly?

Dec 15, 2011

I have a laptop running Windows XP that has a wireless card inside.

I have a Single Board Computer (SBC) running Linux that has an 'wireless access point' connected to one of it's Ethernet ports. I want to be able to transfer data between the laptop and the SBC wirelessly (cabling is not an option)

The 'wireless access point' I am using is the EnGenius EOC5611P - it can be configured for:
1. Access Point

2. Client Bridge

3. WDS Bridge

4. Client Router

I don't know which one of these I need,so working that out would be a good start!

(Engenius ERN 9250) Connected To Wireless Repeater With No Internet?

Mar 3, 2011

I just got a wireless repeater (Engenius ERN 9250) to use in my house, and I'm having issues after setting it up. I set it up using the WPS function with my router (netgear n600), and even if I connected to the repeater my internet would not work. I could access the repeaters admin page wirelessly, and I could ping it (192.168.1.2) just fine. However, if I tried to ping the router it would not work. I made sure that the repeater was connected to my router through the admin page, and I made sure to set the default gateway on the repeater to 192.168.1.1.

Linksys Wireless Router :: Reconfigure WRT54G2 To Work With EnGenius

May 5, 2012

I looked around the messages, but could not find anything on this topic. I need assistance with the CISCO WRT54G2 V1. I have an EnGenius EOC5611P (500mW) Repeater set up in my RV and it connects directly to the PC inside my RV using, a CAT 5 connection. I am now using a laptop and would like to connect to the EOC5611P using wireless. "Can I re-configure the WRT54G2 to connect the 5611?" (I would plug the router directly into the 5611). According to EnGenius support, it is possible, but the router would have to be re-configured, but they do not support this setup. I would purchase an EnGenius EAO 7530 which would work perfectly, but the price is $245.  Here is the link to the 5611 information [URL]

Webpages Take Way Too Long To Load?

Mar 10, 2012

I have 2 laptops and 1 desktop in my household.Lately, I have noticed that webpages take way too long to load. Speedtest reported 2Mbps download and 0.07Mbps upload (that upload speed is not good, is it?)So on my main desktop I looked at the Send/Receive of the packets right after start-up and it showed like 200,000 sent and 7,000,000+ received. that is not normal, right?On my netbook, I looked at the packets and it showed 200,000 sent and 23,000,000+ received. I am thinking there is definitely something wrong with one or both of them.This laptop I am on right now is the only one not suffering from connectivity problems. Without the other two computers connected to the network, my web-surfing is completely normalAnyway, I dont know what the problem is, but I can't do anything on the internet. I can barely open a page on Google with those 2 computers. It's terrible. I have run Virus Scans and Malwarebytes + SUPERantimalware scans and ALL have come back negative. So...[CODE]

Music And Videos Take Too Long To Buffer?

Feb 23, 2012

I use to could be able to watch videos and listen to music, and download at optimal speeds, I could even watch HD if I wanted to, but now all of a sudden (starting at least 3 weeks ago) videos, downloads, and music seem to run super slow no matter what quality I have it on. It takes 5 minutes to buffer a 3 min video, and if I want to watch a show, it take like 2 or 3 hours to fully buffer. My internet still goes fast, and I have trendmicro antivirus, as well as ccleaner, i updated my drivers, i have ie9 and adobe flashhplayer 11.1, i updated everything in windows update, i unplugged the modem for awhile and shut down more often, and opened it up and blew all the dust out. I don't know what else to do. I do have a cisco E2000 wireless router if that's a problem, and both my ps3 and my computer are on the connection, but my computer was working fine with both on the same connection for a year. I go on the http:192.168.1.1 cisco place, and i renewed ip settings, and nothing worked.
