Linksys Wireless Router :: WRT54G Unreachable Host And No Ping
Sep 26, 2011
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 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 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.
I am using the window server 2008 and configure tcp/ip properties correct ping locally reply successful when ping localy but when ping yahoo.com then reply destination host unreachable whereas gateway and dns ip is also correct configure so tell me solution about this problem because i am useing the internet.
I have 2 brand new systems, a desktop running Windows 7 Pro connected with a had line, and a laptop running Windows 7 Home Premium connected wirelessly. Both can access the router, both can access the internet, both can be pinged from the router. However, they absolutely cannot see each other on the network. If I try to ping by name, the addresses don't resolve. If I try to ping by IP, I get either no reply or the "destination host unreachable."I've disabled firewall completely on both. I've double, triple, quadruple checked all sharing settings (network discovery is enabled on both, sharing enabled everywhere, etc. etc.). I've tried disabling all other network adapters on the laptop, no difference. I've tried all of the online tips about repairing winsock.
Can your wireless router do a ping test to 22.214.171.124 [URL] or any other [URL] for that matter?Mine can't, either with my wireless PB G4 running OS X 10.4 or wired Dell running Windows XP. I tried it with a wrt54g v5 & wrt54g v6 both tests got a 'request timed out' with 100% packet loss. v5 had the latest firmware, v6 is still at 1.00.9
I have a WRT54G that has worked fine for years, with some PCs hooked up with Ethernet and various other devices connected wirelessly. I came home this afternoon and nothing going through the router could connect to the internet. I've made no changes to anything recently.
I did troubleshooting with Comcast, and we determined that when their modem was hooked up directly to my computer then that computer could connect to the net. Problem solved as far as they are concerned--my router is busted. But I can still connect to the router, and enter its admin screen, and everything looks fine there. The computers on the router can all see each other. So the router is working.
Once I hooked it back up to the modem my computers all lost their internet, but the router does get an IP successfully from Comcast. And it even assigns IPs to my computers that are hooked up to it. It's just that for some reason they still cannot get past the router.I used the ping function in the router admin site and the router pinged Google no problem. My PCs can ping the router without difficulty. But the computers cannot ping Google.
I've tried every combination of power cycles and reboots you can name. I've tried duplicating the MAC address of the PC that connected to the internet onto my router. None of it has made any difference.
My old router recently died and my ISP was kind enough to offer this Thomson one free. But ever since I got it, my PCs cant see each other on the homegroup. They can all get onto the internet - and by using programs like Dropbox or Teamviewer I can share info from one to the other- but I'd like to get my homegroup working again, Both my PCs are running Win 7, connecting wirelessly to the network. When trying to tracert from one to the other it gives this message: Tracing route to GLaptop.lan [192.168.1.79] over a maximum of 30 hops: 1 GDesktop.lan [192.168.1.82] reports: Destination host unreachable. The problem persists when firewalls on both PCs are disabled, and I've attempted to delete the homegroup on both PCs and re-create it.
My internet connection started to disconnect after an office mate used my PC. I thought it was just the cables but it's not. I pinged my ip address and its okay (sent=4; received=4). But when i ping Yahoo! and other websites, it said that "Destination host unreachable" (sent=4;received=0;lost=4;100% loss). What should I do to make my connection okay? I didn't ask assistance from our IT personnel bcoz they said if i want to reconnect/reinstall connection, I have to get an approved request from our bosses. And I don't like being asked bcoz they are like tyrant bosses.
My company has a Cisco IAD 2400 which is handling our phones and the internet (from Service Provider). We are adding a second router, a Cisco 1921, to our network,I think I have everything set up correctly. One department is using the 192.168.2.0/27 subnet. I can ping each computer within that subnet. Also, within this subnet, I can ping the router interface at 192.168.2.1. I can ping 192.168.1.2 successfully as well. This is the interface on the 1921 that goes to the 2400. However, if I try to ping 192.168.1.1 (interface on 2400), I get "Reply From 192.168.1.236: Destination Host Unreachable" I get the same thing if I ping 126.96.36.199.Within the 1921, I can ping 192.168.1.1 and 188.8.131.52 (random google ip) successfully.
Up until recently one of my sites was able to get to a postilion subnet. Then we started receiving "host unreachable" e-mails. Posting told us SMTP traffic was not getting let in. I've compared the current config to a config that was saved before the issue popped up and found really no noticeable difference.
I tried a packet tracer trace with no luck: SiteB- Firewall# packet-tracer input outside tcp 184.108.40.206 12345 220.127.116.11 25.
Phase: 1 Type: FLOW-LOOKUP Subtype: Result: ALLOW Config: Additional Information: Found no matching flow, creating a new flow [code]...
Result: input-interface: outside input-status: up input-line-status: up output-interface: outside output-status: up output-line-status: up Action: drop Drop-reason: (acl-drop) Flow is denied by configured rule
Attached is a sanitized config. I'm not entirely convinced it's a firewall issue, but I need to some successful testing to prove otherwise.
I am running a Linksys WRT54G wireless router but have my primary computer hard wired to it while my laptop connects wirelessly. In both cases, when I ping my IP's speed test site, I get a solid ping rate of approximately 17-20ms but i also get about 5% failed: timeout's. Now I've seen posts here that suggest wireless interference could be an issue but since my desktop is hardwired into the router, that source would seem to have been eliminated. When I connect my desktop direct to the cable modem the problem doesn't occur.
I have a host that can successfully connect to a PIX 515E (7.x OS) via VPN Client; however, I have no IP routing to the LAN from the remote host.The VPN IP pool works finem,The LAN default gateway is the inside interface on the PIX; the network is flat L2 behind it.The default route on the PIX points out; no other routes are defined,The VPN remote host can be pinged from LAN hosts, but the VPN remote host cannot ping any LAN host, not even the PIX inside interface.
I have used this WRT54gl for several years and it's performed flawlessly both wireless and wired. Recently I've extended the reach of my home network by adding a second WRT54g cabled to the network. I also added another PC in a nearby home with a wireless dongle attachment to the network. In setting all this up I've just noticed that the 'Traceroute' and 'Ping' functions in the original WRT54gl do not work. That is, when in the Administration, Diagnostics window and select either function I get a 'Network is unreachable' message instead of the ping/traceroute information.
All other functions on the network seem to work fine, ie..., I can ping the router from anywhere. Both wireless and ethernet connections work fine through it. The newer WRT54G addition to the lan is setup identical and the ping/ trace router work fine with it.Both routers have DHCP disabled. My modem handles it.
Once in a while, I lose Internet connection and at the same time cannot reach my Siemens Speetstream 4100b DSL modem's setup page 192.168.0.1 ; it happened again this morning (from both wired and wirelessy connected computers). When I go to the router's setup page 192.168.1.1 , it would usually in that situation show that the router has not acquired the Internet IP Address; I power-recycle (a few times) both modem and router and eventually the router reports that it has acquired the Internet IP Address, but there is still no Internet, and the DSL modem's setup page 192.168.0.1 is unreacheable.The situation usually self-resolves only in an hour or so after the time the router has acquired the Internet IP Address: Internet starts working, and the DSL modem's setup page 192.168.0.1 becomes reacheable.
I set this up and I can ping all the gateways but never the hosts. I was hoping I could make these links between 6500's a mix of L2 and L3. Check it out. They are connected in a linear fashion R1--->R2--->R3. I can ping from R1 to R3's SVI4 gateway but I can never ping a host on that SVI4. I was hoping that I could use the port-channels between 6500's as routed links or as trunk links depending on the type of traffic....thought it would ease the migration. I suppose I could always get rid of the port-channels and just make separate L2 and L3 links between the 6500's.
Today one of our 9 Cisco switches a "WS-C2950S" (we also got 2 other WS-C2950S on same network) stop responding icmp ping packages. When i tried to telnet the switch its network was unreachable but i was able to see its existance from other switches by "sh cdp neig". So i decided to fix the situation on a suitable night time work, checking by console cable or even rebooting the device.
Then i started to wonder... what this could possibly be about?We have like 40 clients behind that switch and there was no communication problem during the problem.
I'm going through the CCNA training and I'm setting up my DHCP server on my 871 router. I have my cable modem into the WAN port on my router and have 1 host plugged directly into Fastethernet 1. I can ping any IP I want from the IOS prompt but I only have local access from the host. [code]
I test all devices using ping command, from ASA to router was fine (on both interface) but not to Host , and host to router was fine, but only on directly interface(F1/0), and to ASA was not success. am i miss something in my configuration?
configure my Cisco ASA5510 (asa version 8.3.1) so that one of the host (e.g.192.168.8.20) behind management interface can ping to the other host (e.g. 192.168.2.246) behind OUTSIDEinterface. I tried modifying the ACLs, NATs and ICMP statement, but still failed[CODE]
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.
When I try to ping ipv6.xsnews.nl on either of my Windows 7 computers, it returns "Ping request could not find host". But when I do it on XP, it succeeds. I have tried putting the W7 PC in the DMZ, disabling the software firewall but it doesn't work.
What I think it involves is having ipv6 installed on each. I tried to duplicate the setup of both the XP and a W7 computer, installing the gogo6 tunnel. But apparently it's not setup on this computer because the ping result is the same as on the third computer which hasn't had ipv6 installed. s not setup on this computer because the ping result is the same as on the third computer which hasn
I have a cisco ASR 1002 I have plugged a host into an addressed port and the port comes up however the host cannot ping the router and the router cannot ping the host. Neither can router ping its self. I do the same on a cisco 2800 router and it works fine. What's goin on. Is it the fact that this is a ASR router ?
I'm using 3 AP's 1140 with local authentication using local radius (flex connect mode).the radius server im using is MS 2008 R2.authentication is working great on all devices pc's&mobile.authentication method is PEAP wpa2 aes enterprise.after 3 or 4 hours devices loose connectivity to the web.the device seems to be still connected to the ap but there is no ping to host from local lan or any arp learnd on local router.only manual disconnect on device and reconnecting brings connectivity up again.in one case only reseting the AP's worked.
