Wi-Fi Connection Is Lost And Needs To Be Re-established Wndr4500
May 27, 2012
I have the netgear wndr4500 setup on my home theater shelves which are located in the corner of the room. When using my ASus G74sx with the Atheros 9002 wifi I consistently get disconnected. The wifi connection is lost and needs to be re-established.
Interestingly, when I am using the laptop downstairs the disconnects never happen. I have pored over my router's settings, updated to the latest firmware, as well as installed the latest drivers on the laptop. I also tried setting the router to short preamble and changing the channels to 11and automatic.

We try to establish a Site-To-Site- IP Sec- connection between a Cisco 876 (local site) and a Check Point-firewall (remote site). The Cisco 876 is not directly connected to the internet, but is behind a DSL- Router with port-forwarding, forwarding ports 500 and 4500. The running config of the Cisco 876 is appended to this discussion thread. Unfortunately I get no output when debugging the connection with commands "debug crypto isakmp" and "debug crypto ipsec".
From the Checkpoint-firewall point of view the connection seems to establish, but there is no ping answer.
The server on the local site that should be reached from the network behind the Checkpoint-firewall has a routing entry "route -P add [inside ip-net remote] 255.255.255.0 [inside ip local]" (see also appended running config for naming of ip- addresses). Establishing a Cisco VPN- Client connection to the same Cisco 876 router works fine.

After I change my router, I recently found out that I cannot access remote network resources after VPN tunnel is established. I use CISCO System VPN client. I can see the connection is successful. I cannot ping server on the remote network

All my years on the computer and internet, i've only been connected via ethernet directly from my cable modem as i have just 1 desktop. Anyhow, i just bought a laptop yesterday and so, a router is a must to connect wirelessly. I received an old Linksys BEFW11S4 v4 router from a friend and decided to use it as it's still functional. Yes, i know it's an ancient router but i'm on a tight budget.The setup - I have the ethernet from my modem plugged into the router. I have another ethernet cable in slot #1 (router) connected to my desktop. For my laptop, it'll be a wireless connection.Issue - Now, the connection for my desktop (via ethernet cable in slot #1 on the router) works perfectly fine. I have it set up (on browser - 192.168.1.1), added the SSID, WPA Shared Key and such. The only issue is with my laptop. Everytime i switch on my laptop, i cannot establish a connection (after selecting the SSID and entering the key). The ONLY way for me to get a connection is if i power off then on the router. Each time i turn on/restart my laptop, i'll have to power off/on the router in order for me to get it to work.

I recently swapped a router out for an old one to check an internet problem (to rule it out basically) and when I tried swapping the newer (better) one back in it networks fine (ie computers can see/stream off each other) but it doesnt recognize as being plugged into the internet.
After doing a factory reset via routerlogin.net I still have the same problem. The only thing I can think of is maybe the port got damaged? (The ethernet cables all work fine).
My process for hooking up the new router in case I was doing something wrong:
Unplug cable modem power, swap all the cords, on router while cable modem was rebooting and then once modem connected I turn on router. Did I need to restart the PC as well? Is that why this is screwing up?

I know that N operates on both 2.4Ghz and 5Ghz, whereas AC operates only on 5Ghz. Yet many AC routers advertise as operating on both 2.4Ghz and 5Ghz. So what happens when you connect to an AC access point on 2.4Ghz? Does that operate using 802.11n?
What happens when you try to connect to an 802.11ac access point using an 802.11n client on 5Ghz? Is this possible, or are legacy connections only possible at 2.4Ghz?
I have a Netgear WNDR4500 (802.11n, dual band) currently that I am very happy with. I figure I will eventually switch over to AC. I'm trying to determine if I would be better off simply replacing the N unit with an AC unit, or running both (perhaps WNDR4500 to handle 2.4Ghz clients, AC access point to handle 5Ghz clients, or similar).

I have two routers, one Apple router and a WNDR4500. The WNDR4500 is the second router and I need to have access to the computers and printers on the first router. Right now I have a cable from the first router (Apple Router) connected to the WAN port on the second router (WNDR4500). How do I set up so I can use both routers as wifi access-spots, both have internet and all the printers and computers are available on both? So I can print and share regardless of which wifi and router I'm connected to.

I have time warner internet service and just upgraded my service to their extreme internet. In doing so I had to change my modem to a docis 3.0 modem; the motorola sbg6580. Its a modem that has a router and wifi built in but its really bad and not nearly as good as my net-gear router.

I have a netgear WNDR4500. What I want to do is stream video from my PC to my IPAD using a program I downloaded from the IOS Store. I simply cant seem to get the router to forward the port.
I will post 3 pics showing what I see on the router side and what the streaming program is asking erroring out. The program on my IPAD just errors out and does not see the PC at home at all.

I'm considering adding a dedicated Firewall to my network.Here is what my home network currently consists of:
-Comcast Arris TM722 Broadband Modem
-Netgear WNDR4500 N900 Gigabit WiFi 450/450 Router
-2 x Netgear GS108NA 8 Port Gigabit Switches
-1 x Netgear WN2500RP Universal WiFi Range Extender
-4 Pc's running Windows 7 Home Premium
-Netgear ReadyNAS NV+
-3 x Blu-ray players - Sony & Oppo (2 wired, 1 connected by WiFi)
-Sony PS3 (wired)
-Onkyo TX-NR905 AVR (wired)
-Sony KDL-55HX800 TV (wired)
-2 x Vizio E400 Seies Smart TV's (1 wired, 1 connected by WiFi through Netgear WN2500RP Range Extender)
-HP Photosmart Printer
All wired connections using Cat6 ethernet cabling.So, I want to setup a Gigabit Firewall between the modem and the router (and just use the router as the wireless access point) but I don't want to take a hit on my bandwidth speed.I was thinking of the Netgear ProSafe FVS318G for this.

So I have this Netgear N900 (WNDR4500) wireless router. I have one PC connected via ethernet cable to the router and 4 wireless devices connected wirelessly. As long as the ethernet-connected PC is turned on, the other wireless connections work fine, but as soon as I shut down that PC, the internet connection is lost (although I can still connect to the router via the wireless laptops - router login page - so I know the router's wifi part is working). Why would my PC need to be on? Does the PC handle any of the internet connection for the router?
I hope I don't need to keep my PC running 24/7 so that the other devices can access the internet!

Added a wireless router to our office here so that people with laptops could get on the net without having to physically plug in. Right now it is ok, but the router is acting as it's own DHCP server instead of our server here assigning out the IP's.
The main gripe I have is I can only login to the router through my phone and not through my computer. How can I achieve this. We have multiple offices that all connect through a VPN. I would like our sys admin to access the router at his location as well.
Do I just turn off DHCP on the router and thats it? The model is Netgear WNDR4500.

I have the Netgear wndr4500 router setup as an AP. The wndr4500 has a feature for guest wifi but will not connect to the internet. The main wifi will connect to the internet fine. I'm wondering if I use the WNDR4500 as an AP, the guest features do not work?

I'm not working on a computer now. This is just a question of curiosity since I am still learning networking. I did a reinstall for someone. Once they brought their computer back home their Verizon DSL connection was not working. He could not Ping Google.com.

I had lost power to my apartment and when everything came back on everything was working as normal...until about an hour later when my internet connection was sporadic at best. I called the ISP and they confirmed that the modem is fine. My other computers can connect to it via ethernet cable and wifi so it doesn't appear to be the router.
When I try to ping anything it seems to time out randomly.. (ran "ping Yahoo! -t1" and let it go for a while..times out every 10 requests or so).
I swapped out the ethernet cable but the LEDs on the NIC are Orange(Amber) for both cables. The wifi on the computer works fine. I reinstalled the driver for the NIC.

I have a router with a motorola cable modem connected to my linksys router. In this network I have a windows XP computer wirelessly connected to the router and a networked disk drive wired to the router through a netgear switch.I am trying to move a lot of files from the XP computer to the networked drive.Everything works great as it will move files for as long as everything is up and running. As soon as I attempt to change the status of the modem from on-line to off-line with the push button on top of the modem, my XP computer loses connection to the networked drive.Why is this happening? I would think the xp computer and network drive are below the modem inside the network so losing the internet connection from the modem should only affect the internet connection

Yesterday after downloading something my internet disconnected from my desktop. However, the internet works fine on any other computer in the house. I'm assuming it's some sort of virus or something...I ran McAfee and it found nothing. When I tried connecting yesterday, it gave me all kinds of different reasons why it wasn't connecting when I diagnosed it. Now however, when I try to connect to it, it says the network key is incorrect, which it isn't.

I was trying to browse the internet earlier, and I randomly just lost my internet connection. My homepage loaded up just fine, but then I tried to go to another site. It was taking a while to load. After about a minute a page finally came up that said "Server not found" (I use firefox). I can't get on any websites now and I can't get internet on any of my wireless devices either. When I right clicked my network icon on the toolbar and clicked on diagnose and repair it said "There may be a problem with the DNS. Windows attempted to find the well known host www.microsoft.com using dns. The server responded that the name was unknown." I have Windows Vista. Now I have no idea what I could have done. I didn't do anything out of the normal, just tried to go to a website that I frequently visit with no problems and this happened. This is what I get when I type ipconfig/all in cmd prompt. [code]

recently I have been using my laptop downstairs where the router is in the same room, and now, when I attempt to connect to the network in my bedroom it connects for maybe a few seconds and indicates an average connection and I can also see other available networks before suddenly all connectivity is lost, I can't even see other available networks. Previously I would be able to get strong signal in my bedroom and I was able to use the internet without any fault.I have tested a family member's laptop in my bedroom, and theirs seems to be working just fine in my room. I can only use my laptop downstairs now and I need to know if this is a fault with my laptop's network adapter or if it's a problem with connection between my laptop and the router.

I dont have an internet connection through my computer. This one tells me error 106. I have 3 computers hooked through the same router. So, I know I have internet, as I am writing this now. But for some reason, that computer is now telling me I lost the internet connection. I have tried unplugging everything, restarting the computer, and nothing has worked. I dont know how to get the internet back on that computer.

My wife and I both have Win XP laptops. For some reason, one day we both lost our wireless connection. However, my wife's machine later was able to reconnect - mine wasn't. My machine sees the wireless network, sends the key, and tries to acquire the ip from the router. That's where it gets stuck. The ip address never gets updated.

Network A configuration use like Primary ACS-SJM and ACS-GLX like a secondary for network B configuration use like Primary ACS-GLX and ACS-SJM like a secondary. My solution was working fine about one year ago. but one week ago isn´t working fine. The problem my ACS-SJM lost connectión and user can´t authenticated when the user trye to connect to ACS-GLX either can´t connect. I have to shutdown the ACS-SJM that way can authenticate to the ACS-GLX. I check the log and I didn´t find anything I check the switch.. too where the ACS is connected. but didn´t find anything too.
both ACS have the following IOS version:
