Linksys Wireless Router :: E4200 Received Response From Host (IP Address)
Jun 23, 2011
I replaced my old wireless router with a Cisco Linksys E4200, running firmware version 1.0.02 build 13 May 24, 2011. About once a minute the router sends an unsolicited DNS message to the IPV4 multicast address 01:00:5e:00:00:fb with a destination IP address of 224.0.0.251. The unsolicited message is a DNS response with source port 32784, transaction ID 0, flags 0x8400 (standard query response, no error), questions 0, answer RRs 2, authority RRs 0 and additional RRs 1. The two answers both relate to the router itself: one has Name Cisco18738.local, type A (host address), class 1 (IN), cache flush true, time to live 1 minute, data length 4, and the address of the router. The other is the reverse of the same address. The additional record is for Cisco18738.local, type NSEC, class IN, cache flush true, time to live 1 minute, data length 5, next domain name Cisco18738.local, RR type A (host address).
When my desktop computer receives these messages it logs an error, for example: "Jun 23 07:39:22 sauterws02 avahi-daemon[1067]: Received response from host 10.146.9.1 with invalid source port 32784 on interface 'eth0.0'" The 10.146.9.1 is the router's IP address. I also see these messages on the wireless link from my laptop.I suppose the E4200 is generating these DNS messages in a misguided attempt to make sure there is no old information about its name. Is there a way to turn them off? If not, is there a way to report this to Cisco as a bug?

I have a 6 month old Cisco e-4200 router that is updated to the latest firmware, connected to a Motorola surfboard modem on Sudden-link in Midland, TX.
I previously used this exact same setup on Cox Cable in Wichita, KS with no problems. Upon setting it up down here I cannot get the router to pickup an IP address. I have Power-cycled everything multiple times, did a complete reset and re-installation of the router software and still no luck. The Sudden-link techs have no idea what is wrong. They said that the modems signal is strong and everything should be working.
Actually I did get it to work once for a couple of days, however when redoing the surround sound system I had to unhook the cable line and it quit working and I haven't gotten it to work again since. I have tried unhooking everything. Turning it all off. Waiting for 5+minutes, and then reconnecting in order: First the modem, then an ethernet cable to the computer which will usually work. But as soon as I unplug the cable from the computer and plug it into the router it stops working.

I just bought the Cisco e4200 v2 router, I did all the installations as the Cisco connect software instructed me and everything went fine.After the installation I configured the router on the WAN settings as (Automatic Configuration - DHCP), like my old router (Linksys WRT54GL) and I saw that my router doesn't get the WAN address from cable modem from my ISP(it stays on 0.0.0.0), it doesn't renew the IP address.

After an indeterminate period my E4200 (firmware version 1.0.03) stops renewing the Internet IP address. This happens in both router mode and bridge mode.In router mode the E4200 is set for DHCP and connected to the cable modem, in bridge mode it is connected to a Dell switch with DHCP being provided by my Win2008R2 server.It appears that the device stops recognizing the existence of the Internet port - no lights come on when a cable is plugged in - whether connected to the cable modem or my Dell switch. Plugging the same cable into one of the 4 lan ports and that port lights up immediately (i.e. it is not a patch cable problem).If the E4200 is left switched off for some time (possibly days) it will work properly again for a while.

Frameware version: 1.0.03.
Environment: Internet (external IP say 24.x.x.x) ISP provided modem+router (192. 168. 1.x/ 24 IPTV network) E4200 (192.168.0.x/24 my home network).
The DDNS option page did report update succefully and shown the external IP address correctly on the page, however when I login to dynDNS it shows 192.168.1.x, which is the E4200 IP dhcp from the ISP's router.I know that it's double NAT, but the 192.168.1x/24 subnet is the IPTV subnet, and my old Dlink router did support and update the dynDNS entry properly.

I can connect to the free wireless with no problem on my company laptop. Last night, I was using my personal laptop (as I have been for 2 weeks) on the wireless internet when I suddenly lost connection. In the Network and Sharing center of Windows Vista it shows a connection to the router but an 'X' between the router and the internet. When I run the diagnostic I get "Cannot communicate with primary DNS server (4.2.2.1)" The it says "Network diagnostics pinged the remote host but did not receive a response".

I've got threeLinux Boxes (running Centos 6). They were all connected to my cheap WRT54GL-- DHCP worked every time.Absolutely no problems. Both the LInux boxes and the WRT54GL had MTU set to manual, 1492.I replaced the WRTt54GL with the expensive E4200. I set the new router's MTU to manual, 1492. NONE of my Linux boxes ever receive a DHCP address. I look at the logs, and they do DHCPDISCOVER, get DHCPNACK, try several different intervals, and then fail the interface and quit.ALL I did was unhook cables from the WRT54GL and plug into the E4200. Yes, the WRT54GL was powered off. NOTHING was changed in the Linux configs. Yes, DHCP is enabled, address-range assigned, etc. BTW-- one box is dual boot with Win7-- in Win7 (using the same card, obviously), DHCP works just fine. But, Linux doesn't work.
I can give the boxes static IP's, and all is well. Just can't get DHCP to work. I evfen tried putting in DHCP reservations (via MAC assignments) for the E4200-- still doesn't work. The new E4200 is on the 02 firmware (which I believe is cuurent). If I can't iron this simple task out, in a couple of days I'm taking the E4200 back, and getting a refund. I'll stay with my old WRT54GL... it works. Hate to give up on some of the new E4200 features, though.

I've tried to cascade two Linksys routers, but It hasn't worked for me. The first one (which has cable-modem connection) is the brand new E4200, and the second one is the old WRT54GCv3.[code] However, the WRT54GCv3 doesn't get the IP address from the E4200's DHCP. I've also tried to connect them directly (without the PLC), even specifing an static IP on the second router, but I got the same results.I've to state I don't want to change the first router IP/gateway parameters because I have a web and game home server working with an static IP and I don't want to put it offline temporarily because of readjusting network parameters.

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've updated latest firmware & installed 5 pieces of WRT54GH at our building. Then I noticed each of them disappear from wireless connections list and IP scan list (no ping response). If they might not response to pings but they serve as switch without any problem, I mean there are no wired connection problems, they work as switch all the time. The problems are -again-
1-) Wireless lost and / or 2-) Ping response lost
Turning them off and on again will fix them. But I'm tired of bosses who complain about their faulty pc connectivity.
Don't they run 7/24? I tried to restart them on every 12 hours programmatically/remotely but it couldn't work.

I have a brand-new WRT160N router (just installed FW v3.0.02) that I am using in mixed mode, 20MHz only, Channel 11, not filtering anonymous requests, beacon at 2306, RTS at 2307, fragmentation at 2346, MTU at 1400.
These settings bring the response from a simple ping command over the wireless network down to approximately 6ms on average, which is good. However, when I still noticed inconsistency with my internet response over wireless, I decided to do a test.
By simply running the "ping" command on 192.168.1.1 (the router address) over the wireless network repeatedly (approx 3 seconds between commands), I can see that approximately every 65 seconds or so, router response time increases to over 100ms for a few seconds, then decreases down to 6 ms or so for another 65-70 seconds. See the chart below. The interval looks pretty consistent to me, with the exception of one stretch where it goes for over two minutes without a spike. I see this pattern regardless of what else I'm doing over the network. I do not see this behavior running the same test when physically wired to the router (ping response time is a flat line at 0ms).

I need to remotely monitor a WRT45G from a remote host on the Internet. As such, I want to allow ICMP ping replies on the public Internet interface. However, I have found no feature to allow me to do this. Similar Netgear devices do allow this feature. I suspect the answer is, "you can't do that".

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.

I have changed from a DSL internet service to a Comcast cable system. I have setup my E4200v1 router as an Access Point, to extend coverage in my building. It works fine, but I can no longer log on to the unit using its' IP address 192.168.1.1. The browser returns the message "Internet Explorer cannot display the webpage." If I want to tweak the settings the only thing I can think to do is to push the reset plug, back to factory settings and go through the whole process. Is there a way to discover the new IP address of the reconfigured router? I left the default address as it was when I made the changes to AP status.

Each time I'm rebooting my E3200 device my ping to my ISP is 20ms. Few hours later the ping goes up to 300-500ms.Than I reboot again and the ping is going down to 20ms again.

I am trying to recover a WRT54GS v1 router from a bad flash. The power light is blinking and would not accept pings. Since I figured it was already hopeless, I attempted shorting pin 15 and 16 which cause it to start receiveing pings. My problem is it won't accept the tftp flash, I've tried both cmd prompt and auto upgrade utility. Upgrade utility says "Unable to get response from the server" however it is still accepting pings. Cmd prompt TFTP says it can't read from local file. I am using windows XP. Code...

I have a Linksys wireless router model WRT54G (not sure the exact model, it's not in front of me right now). It has worked flawlessly for the past several years, but for some reason has recently stopped working. I confirmed it's not a problem with the DSL Modem, as I can hard wire connect to my laptop and the internet works fine. It's clear something is wrong with the wireless router. I've tried unplugging, hitting the reset button on the back, and nothing has worked. My computer is able to recognize/locate the router and connect, it's just that I can't connect to the internet. One thing I've noticed under the wireless connection is that the computer is able to "send" packets, but not "receive." My experience is that this is always the case when I experience connection problems, but I have no idea what that means. I was going to call the Help Line, but I see it costs $30 which is likely more than my router is worth and probably 1/2 to 1/3 the cost of a new one so I am trying to troubleshoot myself.

In the past few days I have seen an odd named Client Host "The-Britannic" show up on my DHCP Active IP Table list. There is no device (that I'm aware of) with that name on my network. I delete it but it reappears, and is linked to the same IP (192.168.1.101) and MAC address everytime, so it appears to be a legitimate device. Although it looks like a legitimate device, it's not - so far as I know. I have added the MAC address to the blocked list (internet access / access restriction) to see if I or anyone in-house losese internet connectivity on any. So far, no. Searching various malware and spyware sites turn up nothing.
I realize the IP address is assigned by the router through the automatic DHCP assignement process. I do not broadcast my SSID and have a complex passcode assigned to both the wireless and internal network. Of course, that is no 100% guarentee that someone has not gotten in.I'm running a WRT54GL, all Windows 7 PC's on a home built network. I'll probably change all the passcodes (wireless and Windows Home Network) to see if that disallows access.

Cisco Linksys E3000
I have different types of network clients connecting to both bands of router (5 ghz and 2.4 ghz), and both bands set to WPA2 only. Everything has been set up and working for the past year with no problems.
Suddenly this morning, none of the 2.4 ghz clients can connect and get authenticated. When I attempt to ping them from a Windows 7 desktop connected by a LAN cable, I get Destination Host Unreachable.
The 5 ghz clients are fine and have had no problems. I tested this with the New iPad connected to the 5 ghz band.
Rebooted the E3000 router and the Comcast cable modem, then installed the newest firmware on the E3000 using the web access portal at 192.168.1.1, and still not working.
Changed the WPA2 Personal security mode for the 2.4 ghz band to WPA2 Personal/WPA Mixed Mode, and now all the clients are connected and authenticated and working OK, albeit slower.
What happened? And how can I fix this so I can change the security mode for the 2.4 ghz band back to WPA2 Personal?
P.S. The types of clients that connect to the 2.4 ghz band are 2 Windows 7 desktops, a Windows 7 laptop, and 5 Cisco Wireless N Internet Home Monitoring Cameras. The camera feeds have slowed down considerably using this Mixed mode.

I've tried everything that has been posted so far except for opening up the router itself which I will refuse to do.- Getting = Host Unreachable 192.168.1.20 (I am using 192.168.1.1 as the gateway)- No ping whatsoever even when turning on the router over and over.

I just purchased an E2500. I have a small home network dominated by Mac and Linux boxes, with an occassional Windows machine. On my previous router I had been running OpenWRT.
One of the nice features of DNSMASQ is that it will do local name resolution from the /etc/hosts file on the router. Is there anyway to turn on similar features in the E2500? I have a NAS box and a networked printer that require local name resolution. I had hoped that I could just create a DHCP reservation for them, and that the router would resolve their names for other hosts on the network. This does not appear to work.
Should I just be boxing this thing up and returning it in favor of a unit I can flash better firmware on to?

I attempted to upgrade the firmware on the WRT54G2 V1 (the newer, slim black model) but it failed. I let the upgrade run for about 10 minutes and it just sat there and link to router disconnected I run ping for 192.168.1.1 but response is "DESTINATION HOST UNREACHABLE". The router is now completely unusable and the ALL LAN ports lights are ON and Internet light is also ON.

It worked with these settings in AirPort and here I can't proceed.
