Home Network :: Finding Security Options Behind The Cisco Linksys E4200 Router?
Jul 17, 2011
I have a hobby network at home, the structure of which follows:*Modem * - active SPI firewall -- Then the E4200 distributes data via wifi to/between the following machines --*Server - providing services such as http, FTP, VPN, Mail, MySQL, OpenDirectory, Plex media server, etc.*Two other workstations that access their user details/settings from open directory on the server.Now the purpose of this network other than providing standard access to Internet services from within the LAN is to provide access to the services maintained on my server to users on my LAN when they leave it/go mobile.Now with my limited knowledge of networking I have been using port forwarding to direct service requests through the firewall, however I have found with the E4200 that I have a limited number of custom port fields to use (about 15) which is extremely limiting when I have as many potential services that my server can provide.I could move the Server to a DMZ but then dosen't that put all my other services that have no need to be exposed at unnecessary risk.Do I need to invest in a separate hardware firewall and put it after the modem and before the router?
I'm using the e4200 in a big old house with lots of walls, including rooms separated with brick. Wiring access points would be difficult given the problem of pulling wires. I do have lots of kids and devices connected including DirecTv, iphones, ipads, laptops, and PS3. Is there a range extender? Do I care if an extender only supports 2.4Mhz if I use the same SSID anyway?
Where do I find the security key for the router as there are a series of numbers on the router and the box. Which one is the security key as it's not identified as such?
Have a home network: 2 desktops & 2 printers wired to router (linksys e4200) Want to add nettalk for VOIP telephone service. All ports on the router are taken. What to do?
I recently upgraded the OS on my laptop to Windows 7, which wiped out most of my older Vista settings. When I try to connect to my home network, I am prompted for a security key (network key?). How do I find the security key? I can't find any of the paperwork that came with my router.
By the way, I am currently using my desktop, running under Windows XP.
My wife has a laptop that we want hooked up to the internet through our linksys wireless router. But I cannot remember my security key or passphrase needed to get her on the connection. How do I recover, or find, it?
I have a home network with a Linksys E4200 connected to the ISP's fiber box. The problem is that when I'm connected to the Linksys, either wired or wireless, the connection to the internet will drop after what seems to be a random amount of time (normally anywhere from 2-10 minutes). I can restore the connection by doing any of these things:-reboot Linksys-disconnect and reconnect cable from router to fiber box-if on wireless connection, make changes to the router wifi settings, like change the wifi channel.The internal network stays up, and I can ping both the internal and external ip of the router, but not the fiber box. I have also had the same behavior with an Edimax Wifi AP and less frequently with a Edimax router (once every 1-2 days). I have done everything I can think of:-changed the wifi channels-changed the ip ranges, subnets, turned router DHCP off and back on-booted the fiber box-changed cables-updated all routers to the latest firmware, the network cards with latest drivers...and loads other things that I don't remember right now. For the wifi side of things, there are no other networks in range that could interfere. The same problem occurs on both my and wife's Win 7 laptops and on the iMac (latest OSX). Here's a fun detail: while the Linksys has lost its connection to the internet, I can still access the internet through the old Edimax router connected to the same fiber box, either wired or wireless.
I have E4200 with fixed ip 192.168.1.2, DHCP off connected through LAN ports to FIOS ActionTec as 192.168.1.1. When connecting through wireless network off the E4200, I can obtain and connect fine under Guest network and WEP security, but for any other security setting, WPA, WPA2, Mixed mode, etc. I get the message "Aquiring network address" forever, and I never get a connection.
I set up my daughter's Dell laptop last year to our WRT54G wireless router and I'm trying to connect to our wireless network now with another laptop (a new Dell) and can't find (or remember) my security code or pass phrase. Is there any place on the old laptop that I can access this info? How can I configure the new laptop without this info?
I am doing a security course and I need to find out the IP addresses of the devices on my network in order to carry out a ping of death on one of my devices. I've done the ipconfig command but that doesn't give me the information I need.
Having an issue with a Cisco Linksys E1500 on a home network. The device has a feature to provide a guest wireless network but the guest network can't get to the internet. A wired connection is fine, as is the normal wireless network but not the guest. The cheesy thing is, that it doesn't list an option for what type of wireless security protocol you want on the guest network. I'm assuming that it uses the same security protocol that the normal wireless network uses, but who knowsEspecially weird is that it asks you what password you want on the guest network but then the guest network show to be insecure when you try to connectthought maybe it was something funky with some of my configurations so I went ahead and factory defaulted it and just set it up with an insecure network for both the normal and guest networks. This didn't solve it. The guest network still couldn't get to the internet. In fact, the guest network can't even ping the router.
As an example, I have 3 computers on a home network:
Machine A Machine B Machine C
What I would like to do is isolate "Machine C", so that it cannot communicate with "A" or "B" and vice versa. It should be an entirely separate entity.
Let's say I'm using a Linksys E4200. Is there a good way to configure the above scenario with the default firmware? Is it possible with non-default firmware such as DD-WRT or Tomato? I do not have experience with this but have no problem learning.
My understanding is that this can be done by placing "Machine C" in the DMZ. Unfortunately, I am told a lot of home routers do not have a secure way of setting up DMZ by default. The two routers solution can work but still requires restricting administrative access from "Machine C" and adds an additional potential point of failure.
Friend has an older 2wire home router & has no idea what the security key is to allow me to add my laptop and work at her house. How can we retrieve it.
I was running a Linksys cable modem and 54G with dd-wrt. I had an LG NAS hooked up and everything was working great. I recently upgraded to the Motorola SB6120 and the Linksys E4200. I can not access my LG NAS from outside of my network now. UPnP is enabled, port forwarding is enabled, but I must be missing some other setting that is blocking me from accessing it from work for example.
I am using an e4200 router, Windows 7 64-bit, ipad and iphone. The issue that I am having is that the iPad and iPhone cannot maintain a connection iTunes via Home Sharing. When I start iTunes I am able to access Home Sharing on the iPhone and iPad. If I don't connect right away I will lose this capability. Also, the connection is lost after a seeminingly random amount of time. Also, when if I using the iPhone to listen to music and I pick up my iPad and access the wireless network, the phone gets kicked off Home Sharing. The only way to remedy the situation is to re-start iTunes on my computer. I've been messing around with every setting.
I am looking form accesspoint for home network. I do not need router and usb functionality, I have this already in my linux server. I need only wifi accesspoint with 2 bands and 300Mbps bandwith. Is there a big difference between E4200 or E3200 or E2500? I know that E4200 supports 450Mbps, but I am not planning to buy new devices which could go faster than 300Mbps. Beside of technical parameters in technical specyfication is there a difference in wifi bandwith or tranmission between wifi and cable network?
I am trying to change the security on my router so I can use WPA2 AES security in conjunction with a media device. The router security page only gives me a choice of WPA2 Personal or WPA2 Enterprise (which requires the use of a Radius Server that I don't have).
I just bought a Netgear Router WNR 2000 v3 and installed it. I got inside the router and could set up a Network Name and security key. However, I can not access the internet when I chose a security password using WPA 2, WPA-PSK + WPA 2 PSK, or WPA/WPA 2. It only accesses the internet when I chose None.( no secured ).At this time, my network is unsecured because there isn't way I can access the internet when I create a security key using the 3 options the router offers.
Note : I have tried the 3 security options creating a key number and my computer connect to the wireless network but don't access the internet. It only access the internet when I select None ( no secured )
I cannot seem to locate a good document for SAP (standalone AP) security options to authenticate a connecting device at layer2 and/or at layer3. What the highest level of security I can use with BYOD such as Tablet devices (Samsung) and/or laptops.
I've decided I want to hard wire all my stuff in our family room; however, the modem and router are upstairs in my office. I've got a few options available and wanted to get some opinions from those who have tried any of them. Here are my three options:
1) Install NETGEAR MCAB1001 MoCA Coax-Ethernet Adapter Kits 2) Install Monster PowerNet 300 Power Line Network Modules 3) Run the Ethernet cables through the wall, under carpet, etc.
I'm primarily looking for info about the speed differences, ease of troubleshooting, etc.
Our company is moving to a new location temporarily and we will be looking to do wireless for our network instead of wired. We have a dell power edge 2900 server running windows SBS 2008 and a switch with more than enough ports for what we need.What i need to know is how exactly to do the wireless and what hardware would work best for us. We plan to have approximately 45 computers hooked into the server and have some wired but for the most part wireless. Also we would want to look into advanced security options for our wireless set up as we will be in the same building as a few other companies.
