Routers / Switches :: Dlink DIR 615 Router - Wireless Clients Can't See Ethernet Clients

Feb 1, 2011

I have 4 desktops cat5 to Dlink DIR 615 router. All work fine. Any wireless clients, laptop or netbooks, see the desktop computers for a while then disconnect somehow. All machines can see the Internet through the router at all times. The desktops disappear from the laptop/netbooks but the wireless machines can be seen from the desktop computers but clicking on them gets 'Access Denied' message after a wait.3 desktops = XP, 1 98SE. All laptop/netbooks = XP

Cisco VPN :: 5520 / 5510 - Can VPN Clients Communicate With Other Dynamic Clients

Nov 5, 2012

We currently have an ASA 5520 communicating with 10 ASA 5510's, all on static outside addresses.  I was asked to add 5 additional 5510's on dynamic address.  All worked well in testing until it was decided that some of the dynamic clients needed to talk to each other.

My testing shows packets just dying in the 5520.

Netgear WNDR4500 - Clients Not Showing Up In Clients List

Jul 6, 2012

I have a Netgear WNDR4500 running the stock firmware, acting as a router for my home. I also have 2 routers that are flashed with DD-WRT (Linksys WRT54G and Asus WL-520GU) running as client bridges. The Netgear is and the other 2 client bridges are and The Netgear router is performing DHCP giving addresses from to I have numerous machines connected to the Netgear, wirelessly and wired, and numerous machines wired to each client bridge. All machines have IP addresses that are,,, etc... Everything is working fine, but I have one question: When I access the Netgear router, it shows the client bridges as clients, machines that are wired and wireless to the Netgear router are listed as clients, but the client list does not show any clients that are connected to the client bridges. I assumed that since the router is performing DHCP that all clients would show up.

Cisco Routers :: WRVS4400N Dropping Wireless Clients

Jul 17, 2011

I have several wired and wireless devices connected to the router which is running the latest firmware ( and I have this issue with all wireless devices.  The router is configured for B/G/N Mixed, Channel 6, and to broadcast the SSID.  Security Mode is WPA2-Personal w/ key renewal set to 3600.  Connection control is configured to allow only the desired MAC addresses.  All wireless clients are configured for DHCP (as are some of the wired clients that do not have this issue).  I have tried various setting changes over time, none of which have resolved the issue.
What I have determined, and may be useful, is that each time this occurs I am unable to ping the router from the client and have no connectivity to the internet or other devices on the network.  If I ping the WAP address (reserved for internal use address) I get a response and then connectivity is always restored after doing so.  In other words, I ping and get no response, immediately ping and get a response, then immediately ping and now get a response and connectivity is restored.  If I skip the first step and just ping the reserved address followed by the router address result is always the same.  It would appear the issue is between the the two router addresses.
Prior to owning this router I had a Linksys BEFSX41 that I had for about 7-8 years and a WAP54G I had for about 5, both of which still worked and I never had this issue with my wireless clients.  I went to this router for the increased performance and am very happy with that aspect, however this issue is unacceptable.

Cisco Routers :: WRVS4400N - Some Wireless Clients Have No Connectivity

Jan 27, 2013

We have an office with about 10 PCs, and several other network devices (smartphones, printers, etc). Some PCs and printers are wired, some are not. About two weeks ago, some (6) of the wireless devices lost connectivity. Since then, some (4) of the devices have also recovered normal connectivity.
As of right now, there are two computers, a laptop and a desktop, that cannot use the wireless network. They see the wireless network, connect to it, receive an IP via DHCP properly, have correct DNS servers listed in ipconfig, but they can't ping the router, use the intranet, or internet.

Cisco Routers :: RV220W Not Passing DHCP To Wireless Clients

Oct 9, 2012

I have a Cisco RV220W running the latest firmware (currently, and I have noticed that after about a week of use, wireless clients can no longer acquire IP addresses via DHCP.
I have used Network Monitor on both the DHCP server, and the WiFi client, and can see that the server is receiving the requests and sending a reply, but the client never sees the response from the server.  So far the only way to resolve this is to reboot the router.

Cisco Routers :: Wireless Clients On WRVS4400n Cannot Access Server

Mar 10, 2012

When clients connect wirelessly to the WRVS4400N they successfully get a DHCP address from the Windows 2008 server.  After they have the address they can no longer access the server.  It cannot be pinged, no drives can be mapped and internet access fails because the same server is running DNS.  The WRVS4400N is setup for DCHP relay to the server.  Wired clients do not have this problem.  Wireless clients that connect to a secondary WAP on the same LAN also do not experience this problem.  I have updated the router to the latest firmware version, reset it to factory defaults and reconfigured from scratch.  Turning the server firewall off has not made any difference either.  I have been able to bypass the internet problem by adding a second external DNS server in the DHCP scope options.

Cisco Routers :: RV220W Wireless Clients Lose Internet Connectivity

Nov 4, 2012

I have an RV220W running firmware  I have a couple of wireless laptop users that connect to the wireless without problems, but frequently cannot access the Internet.  They can always access local network resources, but for some reason when laptops are first powered up or are idle for a prolonged period of time, Internet access is lost.  Wired clients never experience this problem and always maintain local network and Internet connectivity.
To get the laptops to access the Internet over wireless, we have to run a TRACERT command from the command prompt to a public IP address, and then all Internet access is restored.

Cisco Switches :: SGE2010 Clients Need To Route Through ASA 5505 And 3750

May 17, 2011

I need to move the client machines off of the 3750 (and their DHCP dependency on it) to the SGE2010 and absolutely route their internet traffic out through the outside interface on the 5505. They must also be able to communicate back into the internal environment in order to communicate with the production servers.
The clients currently use .254 addressing through a dumb dell switch to the 3750 but I am trying to migrate them over slowly to the .253. I know that the 2010 will not do DHCP, so I am putting a DHCP server on that switch right now. The 5505 won't let me add an additional nameif statement onto one of the other eth0/x interfaces and I'm not sure if that has anything to do with it's capabilities to act as a DHCP server (it's not an option in the ASDM) or it's ability to serve as the internet gateway for the 2010 clients. (Side notes: The 5505 has a base license and is currently also connecting 1 site to site VPN. As is the 5520, so all of it's interfaces are used as well).
I statically assigned a moved client with a .253 address and plugged it into the 2010. I have tried giving the 2010 both a .4 address and a .253 address but neither will allow me to ping any of the addresses on the 5505. The 2010 shows automatic routes to the two subnets and I set it's default route to 253.1. The link between the 2010 and the 3750 works - clients receive a .254 address from the 3750 and can get out to the internet via the 5505 and reach the production servers as well.
Why won't the 2010 see the 5505 as a gateway and allow clients to get to the internet and also traverse the 3750 when they need access to the production network?
The reason why I dont' just connect the two swtiches and call it a day is because I also need the production servers to ALWAYS go out/receive web requests via  the 5520 outbound/outside interface. I'm having such a hard time wrapping my head around why i can't get my clients moved over to the new switch, I haven't even grasped how I'm going to do that yet.

Cisco Switching/Routing :: 2960 - Web Authentication On Switches For 802.1x Incompatible Clients

Apr 2, 2013

I am trying to get to work Web-based authentication on Catalyst 2960 and 3560 for clients that don't support dot1x. I followed this guide. Here's the problem: Client (win7) joins the network, opens the web browser and tries to navigate to any http site. The switch forces him the "login" page in which he has to enter credentials. After the client enters credentials, the switch sends http 500 internal server error page and nothing happens. Doesn't matter if the credentials were correct or not. Also i checked radius logs for requests, the switch doesn't even ask radius.
The configuration:
sh ip admission configuration

Cisco Routers :: RV042 No Longer Allows VPN Clients?

Mar 15, 2012

I have 2 RV042 routers.  As of yesterday, for over 2 months, quick vpn has not been functioning.  I had a 2008 server installed; the tech could not get the quickvpn clients to the server, so his solution to give clients access was to map the server to the internet.  As you can imagine, it has been attacked consistently and we have since removed the server. Clients have not been able to use Linksys quickvpn client to connect.  I have had 3 different network technicians, and have been charged way too much for nothing, and the best i got was it being restored to its broken state.  We thought it was a flakey router, but both do the same thing.

Cisco Routers :: No Gateway Being Assigned For RV110W VPN Clients

Oct 22, 2012

I have a RV110W which is am using as a router (not  gateway), because it is connected to the DSL modem (not planning to  bridge it) through its WAN port. The DSL modem forwards all PPTP traffic to the RV110W.The only pupose of the RV110W for me is to use it as a VPN router.
Firmware version:
Below are the settings I have:
 LAN:N.B. The modem runs a DHCP server, so I am relaying the requets to it
 VPN:N.B. Also tried with and networks; same thing.
Routing Settings:
Routing Table:NB: and 10 are VPN clients (created automatically).
Firewall:Users are being able to successfully connect to the VPN; however, there are couple of problems:

1. They are not assigned a gateway; hence, not internet connectivty (i want them to use the remote gateway)

2. They are not able to access the network; hence unable to reach their DNS server and other hosts (run a tracert; they couldn't go beyond the RV110W VPN server IP). For this, i tried to turnoff the firewall on the RV110W, and also tried to create and Access Rule to allow all outboud and inbound traffic between LAN and WAN, but no success.

Cisco Routers :: RV082 ARP Booting Clients Off Internet?

Jul 17, 2012

I have a network of 50+ users with half running XP and half running Windows 7.  Soon we will be upgrading all users to Windows 7.  During the past month a number of the Windows 7 users have reported intermittent Internet connectivity.  I would go to their computer and see that they are getting all the correct IP information from the DHCP server and reboot their network adapter.  Usually one reset of the adapter would do, but sometimes had to reset it twice or three times before connectivity would occur. 
After a few weeks of this more users would report consistent intermittent connectivity.  Just to the Internet, as they were able to reach their folders on our file server and were able to receive e-mails from our e-mail server.  I decided to monitor the network traffic on one of the adapters having the issue using Wireshark, and found an ARP request and reply for the gateway IP.  I logged into the router and found that the reply given to the Windows 7 machine was incorrect, as the MAC address given to the Windows 7 machine was the WAN1 port of the RV082.  The LAN port on the router is and has a MAC of xx-xx-xx-xx-xx-x0.  The WAN1 port on the router has a public IP and has a MAC of xx-xx-xx-xx-xx-x1.  I checked the arp cache on the Windows 7 computers and confirmed that when they have no internet connectivity the ARP cache reads like this:   xx-xx-xx-xx-xx-x1  dynamic
The machine is able to ping every machine on the internal network except for the gateway IP.  Also, after updating the cache to map the gateway IP with the LAN port MAC address, using: netsh interface ipv4 add neighbors "connection name" xx-xx-xx-xx-xx-x0
the issue was resolved for that Windows 7 machine.  However, the issue is ongoing for every Windows 7/Vista machine added to the network.  I do not want to update the ARP cache on every Vista/7 machine introduced to the network.We are running firmware which was updated from just 2 weeks ago.

Uncheck the box if you have another DHCP server on the network or you want to configure static IP addresses for your network devices.Is this accurate?  Or will the RV042 allow more than 50 devices?

Cisco Routers :: SA520 DHCP Lease Clients Removal

Is there a way on the security appliance SA520 to remove someone from the DHCP lease client manually rather than setting the DHCP lease time to expire in less time like 4 hours or 2 hours. I was able to do this on other routers by highlighting the connected device and click remove. If not any recommendations on how to handle the device that are attached via DHCP and the person is no longer here, but the lease time is not up. I have set DHCP lease time to 4 hours.

Cisco Routers :: SRP526W - Forward Or Provide VPN Access For Clients?

Nov 10, 2011

We are having a SRP526W here which replaced a cheap, simple router. Now we would like to set up the VPN-access for outside clients again. So far this was done by forwarding PPTP (TCP 1723 and GRE) to the Windows 2000 Routing and RAS-server inside the network.According to this post the SRP521W, and therefore I suppose as well the SRP526W, are not able to forward GRE: [URL]
Is there a way to provide VPN access for outside clients with this router? Maybe with L2TP (but then we would need to forward ESP) or IPSec (ESP and AH as far as I know)?

If there is no solution we would need to replace this device again with a cheap, simple router which is able to forward GRE - as you can imagine, we would like to save Cisco from this shame.

Cisco Routers :: ISA570W / DHCP Reservation For Multiple Clients At Once?

Jun 4, 2013

All the SOHO routers I have used had a table which shows IP, MAC, Name, etc. In this table, I could easily put a check mark to a check box in a row  that I would like to bind/reserve and IP would be reserved for that specific MAC.
In ISA570W, when I need to reserve/bind an IP to a MAC it asks me to fill out a table in which I have to manually type in the name, IP, and MAC.
Is there an easier way?Is there a way to do the reservation for multiple clients at once?If this is the only way, do I need to copy the mac address of each client somewhere and then reserve IPs for each one manually? This method looks very far from user friendly and efficient, unless there is a very logical reason that I cannot think of.

Cisco Routers :: WRVS4400N Clients That Are Farther Away Connect At A Very Slow Rate

Mar 14, 2011

I have an WRVS4400N configured as a WAN and Wireless router and can connect clients (PC's and laptops) wirelessly thru out the office. The clients that are farther away (10-15 meters and on another floor) connect at a very slow rate i.e. less than 10MBps. I have a WAP4410N configured as a repeater. Immediately after powering up it will allow connections to the 4400 and clients work fine for a 1-2 minutes, then the connections drop and I can no longer connect through the 4410. Nor can I ping the 4410 through the 4400 although right after the pwr cycle I am able to ping the 4410. After another pwr cycle the 4410 is available for another short period.I have attached some info on the configuration of the units and I also have the configuration files available.

Auto-switching Clients Between Router And Wireless Range Extender

Aug 20, 2011

I'm a bit confused about what a wireless range extender gives me. I have bought a Sitecom Wireless Range Extender 300N. This extends the wireless range of your router to parts of the house that have a weak signal or none atall.

It is setup correctly and is working fine, however, the SSID is different from the Router.

Essentially, I want to extend the range of my router to parts of the house that have a low signal. This range extender seems to be the correct product to do this. However, I want my clients to switch to the appropriate wireless access point (either the range extender or my router) depending on the strongest signal, how can this be configured?

When a client is the overlap area (the area where both the router and the range extender can be sensed) I want the client to switch to the strongest signal.

In my case My Router is in the loft and the range extender downstairs. You can still get a low signal from the router when you are downstairs but the range extender give a full signal. However, I dont understand what makes a laptop 'switch' from router to extender when its downstairs.

Because the extender has a different SSID a laptop that can still get a low signal from the router when downstairs doesn't automatically attach to the extender to get a strongest signal.

If I set the extender to have the same SSID as the router

Linksys Wireless Router :: E4200 Routing For 5GHz Clients

May 25, 2012

I just upgraded my in-laws network from a WRT54G to a E4200. It's working but I'm getting issues with the 5Ghz end. I've got both SSIDs using different names.. so its clear which I'm connecting to. I have a macbook pro which has N support and can see the 5GHz SSID.The issue I get is that when I connect to the 5Ghz SSID, the laptop cannot ping or connect to LAN clients on the 2.4GHz end. This includes SMB shares, a couple of devices with web interfaces and one machine running a VNC server. There is also issues with Internet access.. but only sometimes.
Say I have two terminals open.. one pinging Google and the other pinging one of the 2.4Ghz clients. If I connect to the 2.4Ghz SSID, I get both pings working fine. If I switch to the 5GHz SSID, the macbook gets its IP address but then the Google ping will work but the internal ping just keeps failing. The Internet issue.. looking back on the above example.. sometimes the Google ping will also fail. The mac also sometimes indicates that there is no Internet connection behind the wireless connection when this happens.
When I connect on the 5Ghz SSID, I get my LAN IP address from the router (ifconfig). I can also see the /etc / resolve.conf correctly populated on the macbook with thge gateway and DNS settings.For now, I'm just going to get them to only use the 2.4Ghz SSID and assume that a later release of the softeware will fix things.. it could be a compliance issue on the Apple/Cisco N support.
