I have problems in the following scenario. I attached an image with a summary diagram of the network in question. The problem is that on the 3rd floor of the site users connect via wireless fail to connect and receive an IP. But they can not navigate. The second and first floor itself. As you see in the diagram are 3 routers, one per floor. The first is the only router that provides DHCP the other two routers are as simple Access Points.
My phone and my friends phones can connect to the wifi but I cannot receive nor send data from it. The phones work completely fine elsewhere. Here is the kicker, my computer works completely OK on the router and my phone used to work for 3-4 hours before this issue started going again. Now it is constantly. I restarted the modem, default reset it and still nothing. I get an IP address too and it stays connected. Cisco thinks its the phone, but its multiple phones that are having the problem and my phone and other works completely fine at other places.
I can connect via to E4200 with old laptop via G. Great signal and speed (54mps).No such luck on same machine with AE2500(G adapter disabled). Can't find any but one network(neighbors).CD software can't find adapter.I install the adpter manually using normal xp device discovery steps.Seems like there is quite a few AE2500 issues. Should I ask for RMA return? No point in wasting more time in trying to fix Cisco's tech issue.
I've got an ASUS G50V that I normally connect to the net through a wireless router but I recently bought a router so I can make a physical connection and increase speed. However I cant get it to connect to the router no matter what I do (i had it working for a few hours at one point but it dropped off again).I confirmed it wasnt the router but running a crossover cable from the laptop to my desktop, setting static ips on both. Now I can ping the laptop from my desktop but for some reason I cannot ping the desktop from the lappy. I've tried everything I can think of but no dice.
Can receive email but cannot connect to the Internet, my user can get to all shared files on the network and get emails through exchange but cannot browse the internetWe turned off the firewall and checked DNS and the IP. It says the local area connection is connected. We added IE to the exceptions tab in firewall.
I'm working on a project in which we have to transfer our mobile phone calls via internet and our mobile should be connected to pc via bluetooth. This is pretty easy at dialer's end but how to recieve the call via internet on some pc and direct it to the reciever via bluetooth.
We have two Cisco 2960 TT-L switches. I'd like to reduce single points of failure and have dual servers for most tasks. For example, two firewall servers and two web servers. Should one server fail the other will act as a failover.I'd like to extend the redundancy to the switches, and am thinking of connecting one web server to one switch, and one to the other. In the event a switch failed a set of servers would still run, and be able to talk to each other.I'd like to run two VLANs, one for the LAN, and one of the WAN, and connect the two VLANs on each of the switches with the associated VLAN on the other switch.
I have a Dell Insipron Mini 1011 and recently I haven't been able to connect to the internet. The network connection says it's connect to linksys, but it sends out more packets than it receives. What can I do to get it to receive more packets? Could it be my area that's causing it not to connect?
The Lg840g is a tracfone with wifi capability. I get strong wifi signal and connection at home, but receive failure to connect to requested host message when I open the browser. This phone works at wayport wifi, so I assume it's a compatibility problem with the router. Is there a fix? (Router works great with our Acer and Kindle tablets though.)

I have a TL-MR3420 router placed in a remote location. The internet connection is via 3G, and since the telco is shifting the IP every 24 hours, the router is configured with DDNS from no-ip.org. This is working OK most days, but sometimes the DNS fails to update. To be able to trobleshoot it, I am trying to make my router send a mail with the logfile every hour. This function seems to be easy and out-of-the-box, but it doesn't wiork. Whenever I try to mail the log I get the error message "Fail to Connect the mail server.".
It is not possible to enter another SMTP-port, so I asume the standard port 25 (like this thread). Most ISP-mail services require SSL/TLS and/or use an alternative port, so I have made my own server. This server is visible on the Internet, and I (and others) are able to connect and send mails using smtp on port 25. But, still my remote TL-MR3420 keep saying "Fail to Connect the mail server.". I have tried nearly everything, including disabling authentication and giving the IP-address of the smtp server directly instead of the URL.
I recently migrated keeping my original email address. All went well, except I am unable to receive emails from one of my contacts. I can send to this individual successfully, but when the contact tries to respond the reply kicks back to him telling him that there was a delivery notice failure. Email addresses have been verified by both of us and both are accurate
I can connect to my mom's wireless network but now all of a sudden I can't get any pages to load. All I get is this page cannot be displayed screen. My computer shows I'm connected with an excellent signal but I can't get any pages to load, I can't even send and receive my e-mail.
I have my Dell Laptop with model 14R5420, service tag <Admin Note:service tag removed per privacy policy~RK>. It runs normally on Win 7. However, when I upgrage to Win 8, the wireless card can not receive the driver. I list below what I did.
- Download all drivers for my laptop which compatible Win 8 64 bit by using my service tag .
- Install Win 8 (format disk label C)
- Run Bios Driver to flash BIOS
- Set up all other downloaded drivers
All devices work perfectly except the wireless card. In Device Manager, there is still an unrecognized device name Network Device. I know that is the wireless card.If I run my backup to Win 7, everything is normal.
i receive my router signals at my laptop but no internet access. i am receiving this problem from last 2,3 days. Before this it was working fine. I have reset the router settings many time but no results. i get the signals at my laptop but i cant access the internet . some times i got DNS server error.
Windows association failed because Windows did not receive any response from the wireless router or access point. This is the message I have just got out of the blue from my laptop. it is showing that there is excellent strength... And I am also on my iPad connected to this connection.

I recently bought your router and I am trying to install it.The problem that I get is that when the router tries to get the dynamic IP from my provider, it gets nothing.I have typed in the DNS servers but no go. Without the router, my uplink works fine. The provider does not lock onto a specific MAC adress.
my router cant receive any internet from my modem. my internet ip when it is connected is 0.0.0.0 . when my modem is directly connected to the computer, it works fine, i can access the internet, but when it's connected on the router, this problem occur. iv'e tried the solution on the e300(something , i have forgot ) but it didnt work for me. my ISP is DSL btw. i have brought my router on the shop and it works fine. i even brought my CPU at the shop and used my router there and it works also just fine. Their ISP is also DSL . So base from these i've concluded that the problem is my modem?
I'm having trouble connecting using this new card i bought. i have installed the latest drivers and i can find networks and the signal strength is good too but when trying to connect after ive entered the passkey i get the message " no network found" or "did not receive response from router" or something along those lines. i can connect with my older card which is a wmp54g but that one shows less signal strength and my connection breaks from time to time (hence the upgrade to wmp600n) on a sidenote, my wmp600n card works perfectly fine under linux but i want it to run in windows (mainly for gaming) Im running windows vista 64 bit and the wmp600n has the latest drivers installed.
Suddenly after more than a year of running fine, my wap seems to be giving all clients a bad DNS suffix which of course breaks DNS resolution internally (no problem with internet resolution). I assume it's a wap problem since all of my wired clients receive the correct suffix. I'm using a RVS4000 router if that makes any difference.
I have a TP link TD-W8901g modem router with 1 wan and 4 LAN. My questions is can i use this modem to receive wifi signals through wan and give out through lan. i currently use internet from telephone cable. But i have got a free hot spot near my home. Currently i Am using a pc without wireless card.
I'm looking at a dual-channel wireless-N router that transmitts at 2.4Ghz and 5Ghz, but none of our newer laptops even recognize the 5Ghz channel. Is there a configuration setting to change what frequency laptops can recognize? Looking to put 2 newer modle Toshiba loptops on the 5Ghz channel and leave two other...older systems on the 2.4Ghz channel.
I need a router that can receive the signal from my Verizon 4G Jetpack so that I can send signal to items that require cat5 cable.Can the WES610N do that or is there one that can?
Outlook 2007 worked fine with my old router and when our laptops are connected on other networks. But both home laptops take about a minute to go through the "receiving mail" process with GMAIL pop3 accounts when connecting through the new E4200. Everything is factory default, and I reinstalled Outlook. This problem does not occur with the roadrunner email accounts also set up in Outlook
I'm seeing the alert "CPU Receive Multicast Queue is full on Controller" on the WCS from one of my controllers. This is during peak hours and on a pretty busy WLC. I can't find any related lines in the logfiles. I'm currently running software version 7.0.220.0 on a WISMs.
my computer cannot access Internet at all. It finds all the wireless routers and can connect to them, but says that the router cannot access Internet. However, it can. All other devices connected to the router have full Internet access. I've tries rebooting computer, rebooting router, reconnecting to router, reinstalling wireless Internet driver, but still nothing
I have a lab network setup at my house with similar equipment to our office that I use for testing different features and functionality. Since I have had this installed (~ 2 years) I've had an intermittent but recurring problem with connectivity to various wireless devices that I have never been able to fully resolve.I have a 5508 Wireless controller with a handful of 3502i APs spread throughout my house. The controller is connected to a 3560X switch. And I have an ASA 5510 firewall as my Firewall/Internet Gateway. When I work from home I most often work from a desktop computer in my office and have a Windows RDP session to a laptop located in another room in my house on one of my monitors as a working space (I know this is weird but there is a good reason). This laptop is connected via WiFi at all times.Occasionally, I will lose connectivity to this laptop (or not be able to connect back to my desktop from it) and have to start an extended ping from the laptop to the desktop to re-establish connectivity. A while ago I performed some deeper analysis on what was happening and what I found is that when the connectivity breaks the problem is that the desktop is unable to resolve the MAC address of the laptop. It sends out ARP requests but never receives any reply back.
Why would the controller stop replying to ARP requests for the IP address of the laptop?If I log into the controller while this is happening it shows the laptop as a connected client, and has its IP address and MAC address listed fine in the clients section. In order to avoid getting up every time I need to reconnect, I normally hop to a system I control across one of my VPN tunnels via RDP, then connect BACK to the laptop and start the ping to re-establish connectivity back to my main desktop machine. This works because the firewalls ARP cache hasn't cleared yet. And then everything works fine again... unless I manually clear my ARP cache. Sometimes clearing the ARP cache will result in the exact same problem again and I will lose connection. Other times it seems to repopulate almost immediately and the connection doesn't drop.
A wireshark debug from the desktop reveals that ARP requests simply go out with no reply, confirming what is happening.As a note, I have set both the User Idle Timeout and the ARP timeout to 24 hours to try but this has not had any effect.This problem seems to go away and then come back. In fact, I havent been experiencing this issue for probably a couple months recently and then it just started again in the last few days which is why I am back to posting here. No changes to the network were made in the meantime that could account for this change in behavior. I am currently running version 7.2.111.3 but this behavior has persisted through at least four software upgrades so I don't think it's an issue with a specific version but I don't really know.I occasionally epxerience connectivity issues in my house to other devices as well that I use less often like a printer, network camera, apple tv so I now feel like these issues are likely all related.
for some reason some AP's are terminating the association to either one of the controllers for a short period of time. When this happens and the AP re-associates itself with either of the active controllers, it looses the information of what group it previously belonged; and it gets dropped in the default group, broadcasting every single SSID available.
What I would like to see happen is that if for some reason an AP terminates association, but restablishes it shortly; it can automatically go to the correct group.
Both WLC are running the same version and have the same amount of licenses, they can hold all the AP's one of the WLC came down. Config-wise they are identical except that the groups are named differently but ultimately configured the same. If that is an issue we can change it no problem since it's only the name.
