Protocols / Routing :: TPLink TP-8840 Router Led Blinking And No Internet
Jan 13, 2013
I had this problem for 3 months now, at random times I get no connection and the LAN led 1 in my router (which I am connected to) just keep blinking very fast, ADSL and ACT leds are just on. I tried to troubleshoot the problem and it detected 2 problems: "default gateway is not available" and "local area connection doesn't have a valid IP". even when it says that it is fixed, seconds later the problem is still there (sometimes it gives me one problem only). I tried many solution on the forum including reseting the router, disabling the laptop's wireless modem (I'm on a laptop) and even trying ipconfig/release - ipconfig/renew. everything is up to date and I update my antivirus (and it has auto update enabled). here are my specs:
Broadband connection: DSL
Router Make/Model: TP-LINK TP-8840
Anti-virus: Avira free anti-virus
ipconfig data:

I have a TP-Link wireless router which we have always been able to connect to the router with these laptops. My sister has come over to use our internet, which has worked before on her laptop, but now all of a sudden she can't connect to our router, it won't even allow her to type in the password it just says Windows can't connect to the network. I then tried one of our other laptop and after much battling it also refuses to connect to the router. eventually it did, but it still can't connect to the internet.I sat on the phone for about a hour with our network provider (I am from South Africa), and after trying many things, it still won't work. The guy said that there is nothing more to try.

I have att dsl and they supplied me with a modem, a motorola model type 2210, and my belkin surf N300 router is giving me issues connecting to the internet. Im pretty sure my wireless network adapter is a netgear wg311v3.The issue im having is that sometimes i can connect to the internet just fine, and sometimes i cant connect to the internet. I know it is a router issue because when i plug the modem into my comp, i can access the internet 100% fine.I also think it is not a wireless network adapter issue because i ran an ethernet cable from the router to my comp and had the same issues. There are 2 other computers on the network, one of them is a year or two newer than my dell desktop, and has no issues whatsoever connecting to the internet via the router. The other computer on the network is a Wii, and has connection issues when playing online (probly a different issue), but can access the internet no problem.

I have a little problem with installing my new router. There were quite a lot of problems with the old smc, so I've bought a TP-Link router. I installed it just alright, it said congratulations, you have internet. I don't have though, not even on the directly plugged computer. It's kind of frustrating, since the old router is still working like before. So I plugged an ethernet cable from the old router's lan to the tp-link wan and with that, the new network is working just fine. The problem with the internet access occurs only, if the router is directly plugged to the modem. (The computers do find the network but the connection is kind of offline.) I don't really know what could be the problem, since I'm a little new to routers. I've read almost everything in the new router's manual and I'm pretty sure it's installed correctly. (ADSL username and password copied from the old settings, mac address copied, all ip addresses pinged, done power cycle etc..) I thought about resetting the modem, but I'm a bit afraid of losing the old router's internet connection as well.

i have a adsl modem tp link td 8840, and i had this up and running well for about 3 days. then we decided to get a router cause my little sis got a ipad2.the router is dlink dir 61.so basically i followed all the instructions and the internet was working fine.then for some reason ign site stopped working, i thought that it was down for some reason and didn't think much of it and today when i tryed to go into hotmail or facebook it doesn't work either. so i can get into the log in pages of both, but when i put in the id and password, the screen goes blank and just says waiting for .... on the bottom (using google chrome).and it never loads.i tryed with other internet browsers and it din't work so i took out the router and re wired the adsl modem only and voila. all the sites started working again.i want to use my router but i don't know why i can't acess some sites when i have it connected.

Basically I have a win2000 server running as a VM in my computer with a secondary LAN address(Different subnet) which acts as a gateway for the other devices on my network (e.g. my wifi-router has DHCP relay set to my VM's address). The VM uses another network(internal NAT) for accessing the Internet though my computer. So far, I've managed to set up the DHCP and routing. Other devices on my network have access to the internet. But, since my computer has only one NIC, and even though the VM uses a secondary IP address, it's still on the same network as my internet connection. There are computers that belong to other people, who I do not want to give access through my router(even though their computers are picked up by my DHCP). I was given only one IP address for usage on my computer. This is why I wanted to add some kind of an authentication procedure(like some sort of PPPoE login maybe?)so as to prevent unauthorized usage my my connection. The question is, 'What are my options for the authentication procedure, and where do I start?' If my explanation was unclear.

I have TP-LINK TL-WR740N router and I am trying to configure it to work with my Broadband cable over PPPOE.The router once configured show status as connected with a proper IP and DNS servers. When I use the routers inbuilt ping utility to ping Google or any other site I get a reply.But when I connect my computer to the router on the LAN port I see no internet on my computer. I am able to ping the router address but not google.I tried disabling all Firewalls and Antivirus I have but problem still the same.Also I tried connecting over WIFI but still no internet.I also called up TP-LINK helpline several time and got my router replaced. They also tried a few settings on my machine but no success.

I've got a problem with my Linksys E1000 router. When I bought it, it worked without trouble. Setup was easy and straight forward and I was able to connect all my wireless devices (2 latops, a mobile) without any problem. Then, after two months or so, I noticed the laptops were losing internet connection (or not finding the wireless network on start up). Rebooting the router seemed to work the first couple of times to restore the wireless connections, but after a few more days, the wireless network either shows up and the devices are unable to connect to it OR the wireless network does not appear in the network list. However, the wired connection to my desktop PC via ethernet cable has no issues at all. My conclusion is that these wireless routers (E1000) have a defect in the radio card.

I have a Compaq mini CQ10-100 Netbook, and I am trying to Make a Wireless internet connection through a D-link router. My ISP is Cox Cable. The Netbook is connected to my wireless network, but will not connect to the internet. It keeps asking me to transfer information, via thumb drive, from a wireless access point, but my router is my wireless connector and it doesn't have a USB port to plug in a thumb drive. How do I get this netbook hooked up to the internet?

A couple nights ago, in the middle of my surfing the net, i was cut off and 'checked the modem (working good) and the router, displaying blinking amber lights --modem and internet. I had to restart my router, usually, it would work after that and i could surf again. This time, when it started back up, the router light turned blue and then the modem and internet light started blinking amber. I haven't done anything except chat over the net when it happened. All other lights are blue. I have cycled the modem power, the router power, and restarted the computer and have the same results. I already followed the troubleshooting from Belkin support 192.168... completely restore it to it's factory settings and yet, i still end up not being able to connect in the internet and with that blinking amber lights. I already tried connecting directly from my modem to my win 7 laptop --no problem at all. I could surf and chat. but when i tried connecting it again from modem to router so i can do wireless.

I have a Linksys WRT54GS vers 7.2 Router on an iMac OS X Leopard. The other day I was in the middle of downloading an upgrade for the router when Firefox gave me this message: "Firefox can't find the server". I was no longer able to access the internet, and the router's green power light was left flashing. It flashed for over 24 hours. I tried unplugging the router and shutting down the computer, then plugging in the router and turning on the computer. (I don't have a modem.) The light was still flashing. I tried pressing the logo button for 5 seconds. Still flashing. Tried pressing the reset button in the back. Still flashing. 'I can't get on the internet or into the router. Linksys live chat gave me a link to "Upgrading the router’s firmware using the TFTP utility", which involves a download, but I can't download anything because I can't access the internet.

Is this a wired or wireless connection issue? Both Who is your Internet Service Provider (ISP)? Comcast..What type of Broadband connection are you using? Cable..What is the exact Make and Model of your Modem, Router or Modem/Router Combo - (Main)Netgear WNR3700v2 / WNR2000v3(secondary) My current setup is the 3700 router is taking the internet from the modem cat5e and spewing the wireless. I would like to have the secondary router use the wireless from router 1 as the internet source and push the internet out of the 4 hardline ports so I can plug my upstairs xbox 360 into the router via cat5e. I'm just kinda new to this and still learning so I'm not sure how to configure the router to do this. I can get into the settings of the router just fine but finding the right settings to tweak is a little difficult.

The whole thing about IPv6 has been out for what is probably a couple of years now. But I find it very odd how even my newest modem/router can't even support it yet. Why on earth are manufacturers such as Netgear holding back so much on making their products IPv6 compatible? The IANA has just about given out what is left of the addresses, and we still have time to adapt by working our way over to IPv6 as it can work simultaneously with IPv4. Companies have been given years to prepare.
Why can't I connect to the Internet right now using IPv6? Not only is my router holding me back, but will my ISP hold me back as well?

I purchased an IP Cam for my girl friend to monitor her dog, she lives in an apartment complex that provides internet. I have been able to get the camera setup at my house to be accessed through the internet. I have a cable modem and a router, setup a dyndns account, port forwarded my router and boom it worked. Went to my gf's apartment and I didn't think of it at first until I was frustrated, but realized the apartment complex probably has a router of its own. I can access the cam on her LAN but not through the internet.

Basically, I was following instructions of how to forward a port to get higher speeds on bitcomet.After doing allsorts which I don't understand (yes, very stupid I know, but I've learned my lesson now), I restarted my computer and have since been unable to connet to the internet.
I have tried a system restore which didn't work and also searched google for hours but to no avail.When I diagnose the problem with windows,it states," "Wireless Network Connection" doesn't have a valid IP configuration.I am running Windows 7 btw.

We have a PPPoE DSL link with a dedicated IP providing by a small ISP(ISP A) in Canada. We are having trouble reaching a small group of IPs in the US to be able to access some client resources.We have eliminated all possible local issues by removing the firewall and making a direct connection to the ISP. We have also had numerous tests prove successful when we use other local ISPs.
Trace routes show that the packets get dropped a few hops from the destination on a US ISP(ISP B).The routes even appear to be very similar to the other ISPs we tested. We escalated to ISP A and they say that everything is working properly on their end and the problem is with ISP B. They claim they "have no partnership with ISP B and therefore cannot create a ticket to get it resolved". I tried calling ISP B but I get nowhere because I am not a customer of theirs.
My solution is to give ISP A the boot, but management has denied that request because of the amount of effort required to switch over. How I can escalate this? Is there anyway to go over and above the ISPs?

We have Linkline ADSL that was set up by them with a Netopia 2241N-006 modem and a Cisco 33674 wired router. We got a Cisco E2000 wireless router to replace the wired one. It sets up perfectly, in that I can see and connect to the wireless router just fine, but it has no Internet connection. Also, when we plug the cord straight from the modem into the computer (as was suggested by someone) it has no Internet connection, so it seems we need the Netopia modem for it work.I have connected to Cisco live chat three different times to try and find out how to make this work, and each time after making me give them all the information they insisted the uninstalling/reinstalling Cisco connect and then going through set up again it would work. On the second and third chats I even gave them the reference numbers for the previous chats so theiy could see that is what was already done, to no avail. Apparently that is the only solution they know.Then I called Cisco support on the phone (twice). The first time they insisted I hang up and I repeat the same procedure from the chats, even though I explained I had now done it three times and gave them the chat reference numbers. They said if I would not do that. The second time I called they told me that was not something they supported - using their router with an adsl modem - even though their instructions do cover it.
using the two routers together since I cannot get the wireless one to work alone. I went and bought a crossover cable, hooked the two routers LAN port to LAN port, changed the router's IP address to just outside the main router's range and disabled DHCP. This did not change anything, so I tried the one other idea I found online which was to assign the router a static IP address in the same range that the rest of the network is using, hook the two routers LAN port to LAN port with the crossover cable, and disable the DHCP. This did not work either.

Applications such as skype, teamviewer, etc, are all working fine, however, when I try to load certain webpages, such as Facebook and forum boards, they don't load, just stay white screen.
Youtube, google, both load, I imagine this is because they're both on the Google servers, apart from any Google related sites, I can't find any that will load for me.
I think this is a problem wth my DNS addresses, I've tried a range of solutions, clearing my DNS, changing my IPv4 address, restarting the router, PC, but I can't seem to find a fix.
Running on windows 7 Home premium
NOTE: I had the Metropolitan police virus yesterday, I did a system restore to remove it, my internet worked fine after, it's only since I've moved from the router at my other house, to the one here that I'm having problems.
