Linksys Wireless Router :: WRT54GH No Ping Response After A While?
Mar 29, 2012
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".
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 have the following LAN setup: I am trying to ping the Wireless Access point (10.60.1.1) from the Cisco Router (172.16.88.21) but I am not getting responces. I can however ping 10.60.1.1 from server (172.16.88.36). Tracert from the server shows that it is going through the Rotuer and Firewall.
I don't know how to access the router now to reset my system. My wired computer works fine. I have used this router without issue for several years. I used windows Xp and now I installed windows 7. After that i cannot connect to the router. I tried with 192.168.1.1 in my browser and with the setup CD. I just cant enter to setup the router. On the other computer the internet is functioning perfectly. I use the same cable, so the problem is not in the cables.
Firmware version is V1.0.01 b001 my WRT54GH has recently started to shuts off periodicaly without any reason. Will stay off for couple of minutes, then will turn ON again. In this period, On/OFF button has no effect.
I need to set the local IP for my new wrt54gh wireless router to 172.28.2.x & netmask to 255.255.0.0 but there is no option to set the netmask to 255.255.0.0 in the drop down menu / list .
have problem with WRT54GH, almost every second page after reload gets an error message: Error 101 (net::ERR_CONNECTION_RESET): The connection was reset. Tried both on IE, Firefox, Chrome Tried to disable antivirus, no effect, the pages still load not all the time, firmware upgraded to the latest version. Before didi not have such problem with Zyxel W330EE.
I'm not able to logon to WRT54GH-SG over 192.168.1.1. I'm using correct password & have NOT forgotten. I'm hitting 401 page. The support rep told me reset the router which I do not want to before I explore any possibilities.
Ive been using this router for about 4 months now. suddenly it wont let me connect wirelessly through itouch nor through imac. it says Unable to join the network "linksys" eventhough "linksys" is indicated to be an available WIFI network and that signal is full. Problem is still the same even after i reset the router a couple of times pass 30seconds, set the security to No Password.if i connect the router with a cable it connects seamlessly and allows me to go online.
I have a linksys WRT54GH wireless router running firmware v1.0.01 build 001.It's setup with DHCP.My desktop computer is connected to the router via cable.I also access the connection using my laptop, via wireless.The problem is that after I start using the desktop (wired connection), I can't connect from the laptop using wireless. It happens every time. I then turn the router off and back on again. After this procedure I can successfully connect from both the desktop (wired) and laptop (wireless).
I purchased WRT54GH wireless router back in 2009 and it was working fine except for past 1 month, wherein the Internet Connection was being disrupted 15 - 20 times in an hour. I thought it could be fault from ISP end; however after investigation by ISP we found the fault was not from ISP as, when Wireless was unable to establish connection with the DSL Modem it was failing but when tried to connect laptop with the DSL Modem it worked fine (Wired connection). I did try the Settings mentioned in an earlier post to change the UPnP and the Beacon Interval etc. This however doesnot seem to work as the internet has been disconnected almost thrice since then. (Approx. 15 - 20 mins). When the router is unable to connect to internet I restart the Wireless Router and the DSL Modem. After restarting, the Internet connectivity works fine.
Below are the Advanced Wireless Settings from Wireless Tab:
I just bought WRT54GH router. I have one PC (running Ubuntu) connected via Wireless.Every 5-10 minutes I get disconnected for a short period of time (about 10-30 seconds). During that period I am able to access router configuration page, but can't connect to the "outer" world... Surely it's not about my Internet provider, since connecting the PC directly to the Internet cable works fine with no "disconnections".
I was using a wrt54gh which is no longer in working condition.. so i bought an E1200.the problem i face is when i try to restore my new router which is the E1200 frm the backup file frm my previous router the wrt54gh which is saved in my computer i get the error message " THE IMAGE FILE IS INCORRECT ".
Anyone has a register of problems between a router WRT54GH and A495 telefone of Siemens?I mean they can be working in the same frequency, that´s why in some rooms I can connect my wireless network very well.
i am a using a WRT54GH linksys router.. which was working fine for a year.. there was thunderstorm and lightning a few days back.. since then my routers internet port (the first port which says internet in yellow) has stopped working..
I just installed WRT54GH and wireless was working fine, after almost 3 hours passed I lost connection with it.I tried to connect using wireless with 3 different notebooks without success. Just using cable it works.I upgraded firmware from v1.0.010 to v1.0.01 but still not working.
I have a WRT54gh, and the signal strength is extremely poor. Full strength at about 15 centimeters, Then drops to 50% at 50 centimeters. By 1.5 meters, the signal is extremely weak or not visible. Have updated to the latest firmware, factory reset and power cycled. There are no other wireless networks or devices that would provide interference Have experimented with channels, thresholds, transmit type, encrypted/open, intervals etc..No luck. Due to signal dropping off so quickly it seems like a transmit strength issue rather than an issue that can be solved in the menu. I'm wondering if there's a way I can console log-in to the Linux kernel and check the transmit strength and perhaps bump it up by a few DB? It's out of warranty so a solution involving opening the case is also acceptable.
I want to change ping latency because my application cannot run in 1ms or 35ms it will work on 600ms to 1500ms due to in VSAT minimum response time latency is 600ms to 1500ms.for i want to change in my 2003 server reponse letancy time.and we are use online accounting software and connecting through ftp server.kindly do the need full how to change response time frame in windows
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.
A network administrator wants to capture some network data. He opens Wireshark software, start capturing, and does the following:In PC-A, runs a command in command prompt. The network admin issues the command and sees there is ping response from the google.
I connects to the wireless box and has full signal but an exclamation mark is present.I have run some tests and the IPv4 and IPv6 say they have no internet access.I also run a full test and everything passed except the ping test which failed and it said: no response:default gateway response: dhcp server it suggested disabling security firewall but i'm not sure if that's the correct thing to do or even how to do that!
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 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'm trying to configure an ASA firewall (FW2) for syslog and tacacs and am experiencing strange behavior. Both the syslog and ACS server are on the inside of another firewall (CoreFW). Whenever a log message is generated on FW2 the request is dropped by CoreFW and message '%ASA-4-313004: Denied ICMP type=0, from laddr FW2 on interface outside-b2b to syslog01: no matching session' is displayed. The same thing occurs for tacacs.
It appears that the syslog and ACS requests are generating ICMP echo replies, which the core firewall drops since no session exists on a lower security interface. I have access lists configured on CoreFW to allow the syslog and tacacs requests.
FW2 is running asa825-k8.bin, CoreFW is asa824-k8.bin
We have Four 2960S Switches in Stack. We have created Multiple VLANs. While Pinging from Member PC to Member VLAN IP on Switch, we are getting Higher TTL response & Some ping breaks for One Particular VLAN. While pinging from Member PC to Member PC, we are getting Normal Ping Response.
We got a switch issue here for 4507R-E with two sup6l-e supervisor running sso redudant. and we found that sometimes client can't ping through the local vlan ip add on the switch , can't logon the cli by telnet too. In the direct connected network device such as access switch and ASA , can't ping or telnet the 4507R too. when we made a forceswitch to sso standby supervisor from console , the problem solve and everything get fine . after that, we switch angin back to the origin supervisor , fine too.
before we made the supervisor forceswitch , we had check the system cpu usage is 15 - 20 % from console . also we had creat a new vlan 200, attach the notebook to 4507's vlan 200 port , the notebook can't ping or telnet the vlan 200 ip interface too.
