I have a dell inspiron 15 and I've been having trouble fully connecting to my wireless internet. It says I have signal but gets stuck on identifying the network and I have limited IPv4 and IPv6 connectivity.
Here's the ipconfig if you can identify the issue with it:

I am using window 7 on my laptop. I am using broadband internet (not wireless etc) via my external lan card but IPv4: IPv6: No Internet access shows.
View 4 Replies View Relatedwell a couple days of go it was working fine until i updated windows 7 now it says im connected to the internet but when i go on it dosnt load anything, and when i go check it says that "IPv6 connectivity: No Internet access" how ever the IPv4 is connected to the internet, should i restore settings to osmetimes earlier this week
View 2 Replies View RelatedMy laptop is not connecting to the internet, I know that it is not a router problem as my mine PC and Notebook are connecting with no issues.I have removed all router devices as had an new once once it was last working.I tried this morning to set it up again without success. I have compared to setting with my pc and have found the difference is with the IPV6 connectivity.
View 6 Replies View Relatedhas quite frankly gotten me absolutely annoyed . I've tried just about everything, from using the netsh commands to changing the dns to 8.8.8.8 or that other one or the other. Nothing is working, I unplugged the router, problem persists, I disabled IPV6 problem persists, I restore, problem persists. The only clue I have is my router, and mysteriously, there are TWO of my computer on it. It might be nothing but most certainly has caught my attention. Also, it gives me this info about my media being disconnected
View 14 Replies View RelatedI've just want to confirm if I can protect a router (telnet and ssh) putting 2 ACL's (one IPv4 and other IPv6) on the same line vty. Something like:
line vty 0 4
access-class hostsIPv4 in
ipv6 access-class hostsIPv6 in
Do I have to use named ACLs?
our company backbone is hp 5406, and desktop switches are hp 2510 currently we are working with ipv4.if we want to start use IPV6 for test environment, what’s things we need to enable in our backbone/regular switches.i mean for example if we want to set static IPV6 address for 2 servers and send ping between them, or even make new vlan with IVP6 subnet, and use it like regular vlan but with static ip's(until we got ipv6 dhcp).i have hp 5406 manual for IPV6 but i can't understand what i really need to do for start using IPV6.
View 5 Replies View RelatedRecently I wanted to setup IPv6 for my home network. I signed up for tunnelbroker.net service and was provided with IPs. Then I configured the IP address in my DIR-615. But It's not working..
Screenshot of IPv6 config (router) : Screenshot of my Win 8 network Config : I also tested at [URL] but failed...
I currently have ipV4 as the setting on my DIR-825. Other posts seem to want ipV6 which is more secure but is not possible with a DIR-825 Rev A1. I have two routers, a primary router (DIR-825 Rev B1) capable of ipV6 and a secondary router (DIR-825 Rev A1). If I implement ipV6 on the Rev B1 router but keep ipV4 on the secondary router, will this improve the security, or will it just mess things up so nothing works?Certain devices (cell phones and most Tablets) don't deal with ipV6 very well at all. The ones I have tested flat don't connect to the wireless network if the router is set at ipV6. Is ipV4 adequate for a Home/Small Business Network when trying to implement Remote Access and VPN?

Is it possible to do static (inside,outside) with the outside address being IPv6 and the inside IPv4?
If yes, is it possible to do this in parallel with an existing static mapping that goes IPv4 to IPv4?
I have a Dlink DIR-825 B1 with firmware 2.05NA. I recently reset it to factory defaults to make sure I didn't misconfigure something.
I have been struggling to get a IPv6 in IPv4 tunnel working with tunnelbroker.net. I think the issue is a problem with the router itself and i'm not sure how to get it fixed.
All of my machines were getting IPv6 addresses (both windows, mac, linux) but none of them seemed to work. All I was able to do was ping the gateway itself using the local lan address. In each case they were missing a default IPv6 route. If I added a default route then it would work.
I started looking at the packets using a network sniffer and the Router Advertisements all had a Router lifetime value of "0" which is RFC4816 speak for "don't use this router as the default router". So Windows/Linux is exactly right by not setting a default route.
The strange thing was that when I reboot the router I would briefly get a router advertisement with a lifetime of 1800s, the corrert prefix and dns server but then another router advertisement would come along 5 seconds later with a router advertisement of 0.
I have TCP' Other observations
... using 6to4 I would get working IPv6 address. The difference again seemed to be the Router Lifetime. But I want to use a permanent tunnel. I have found 6to4 unreliable.
... the router never responds to router solicitations. It only sends a router advertisement when it wants to.
... the router never responds to DHCPv6 when that is configured.
Would like to learn from you what tools I could use in a Network that provides IPv6 visibility and also completely blocks IPv6 from being tunneled through ipv4 only networks.
I have tested this from Linux running some internal penetration test apps,but specifically running Teredo tunneling in Local LAN that is able to completely bypass security paremeters such as websence filtering servers and be able to accessing internet IPv6 sites, even its equivalent IPv6 address based on its IPv4 PAT address could be pinged from outside.. is like the PIX firewall never existed - wide opened door .
Blocking in outbound and inbound direction udp ports 3545 and 3544 seem to done the trick in dropping IPv6 at the PIX/ASA from being tunneled out or in.. Is this so ? Realy ? not to fast!! None of our local systems - users PCs or servers have IPv6 stack enabled as a policy, however, in reality this poses a serious thread.
For example, Teredo tunneling running in a host inside LAN say by a user who is a hacker can use different UDP ports from the standard listening udp 3545/3544 ports, host will still be able to tunnel IPv6 through IPv4 again, in this case I want to have tool or a strategy that can detect this internally beside being blocked at the firewall, I am looking at AIP for our ASAs would this help? What other tools could I utilized to have some sort of IPv6 awareness in our LAN without having to rung IPv6 that can provide some visibility of this invisible traffic in IPv4 LANs.
i got trouble for this ipv4 & ipv6 fragment trafic prob/attack.how do i prevent it from comming in to my network? is it way to prevent it in cisco router part?
View 2 Replies View RelatedI'm working on a computer that has no connectivity on wired or wireless connections. the wired eth card is a broadcom netlink card and the wireless adapter is an atheros ar5007eg. I found the drivers for the wireless on acer.com and removed the driver that was on here at first and put the one from acer. i cant find a network in range but device manager says its working fine. Then I found out the wired connection isnt working either and im getting the same messages from windows troubleshooter. It says both are "experiencing driver or hardware related issues and "make sure your internet protocol bindings are correct - ensure that ipv4 and ipv6 are selected in the config for the network adapter". it links me to the connection properties and ipv4 and ipv6 are checked off for both. futhermore, in the connection status window it says i have no ipv4 or ipv6 connectivity.

I have a virtual machine running in my desktop which connected on the gigabit lan port on EA4500 with firmware 2.0.37.What I want to be able to do forward a port that came from an external ipv4 address to the ipv6 address and a different port to my virtual machine (to remote desktop port 3389).The reason I want to convert the traffic to ipv6 is because virtual machine is running vpn and is not reacheable through ipv4 (unless bunch of routes are setup and things get complicated etc). I verified my phsical server and virtual server get both ipv6 ip addresses through ipv6 tunnel from comcast. Without tunneling I could not get ipv6 setup using automatic mode with comcast, it simply did not work for some reason.

I lost my internet a few days ago out of the blue. I have been in contact with my internet provider with no success. None of the troubleshooting options have worked and my security software is giving me warnings; but is unable to scan or update. I've rebooted, done a system restore and reset my IP settings via DOS, which has not worked either. I have full connectivity, just can't identify the network and therefore can't get passed to the internet. I have Windows 7.

I am running Windows XP SP3 on a Dell XPS
I am currently on Time Warner Cable 10 mbps packge, and am using their wireless DOCIS3 modem/router. It is connected in my bedroom to the main computer. That computer stays connected. However, throughout the rest of the house (we have a two story townhome) it will drop completely or give limited connection...constantly. Sometimes I can have my laptop next to me and it will go out or give limited connection. The connection speed never drops, it just goes completely to no connection. Not for sure what is going on, if its on my end or time warner. Has been doing this for quite some time, the cable company comes out and changes the modem, but that's it, couple days later, goes back to doing it again.

I have a d link dir 615 "ipv6 ready". My internet provider give tome a native ipv6 /48. I configure the router with my ipv6 /48 address the internal propagation of the address is good.
On the status ipv6 page all seems OK marked "connected" but I can't have an ipv6real connection and my provider say to me that i am not connected.
Is there a known problem of connection between an public /48 and the internal /64 and if so could it be corrected.
My ISP provides IPv6 connectivity in the form of dual stack IPv4/IPv6 with DHCPv6 Prefix Delegation. Using a Cisco IOS-based router I managed to make such a connection by using as a template the Cisco IOS configuration file that my ISP has posted as an example in the following link:
[URL]
The main point on this configuration is a PPPoE connection with:
interface Dialer46
ipv6 address autoconfig default
ipv6 enable
[Code].....
configure this router according the Cisco IOS configuration file I linked on the top in order to have a working IPv6 connection?
We have a 2100 cisco Wireless LAN Controller which manages 3 APs and assign IP address to clients which connects via wifi. Currently, we are deploying dual stack IPv6 and our consultant stated that our current controller does not support IPv6.
This is rather odd statement because there is an option to enable IPv6 in the advance tab of WLAN. And sometimes clients (win7 and Mac OS X) are getting v6 addresses, able to ping v6 sites, and reach v6 sites successfully. And other times, clients do not..or getting the v6 address for 10-15minutes, then unable to ping/reach v6 sites.
Our consultant is sticking by his words saying it does not support. If this is true, then clients should not be able to get v6 at all....not sometimes and not other times; very inconsistent.
And what is ipv6 pass through? What is ipv6 bridging?
We had a lightning strike near the house and it fried my NIC card (or so I thought), also my power strip. I replace them both along with my Ethernet cables. My internet intermittently goes out, every couple of minutes. I keep getting pop ups saying "Local Are Connection has limited to no connectivity" and/or "a network cable is unplugged".

Another wireless laptop runs from house 2 and connects to the modem in house 1. However the signal on the laptop in house 2 has become very weak and keeps dropping out. I have tested my laptop in house 2 and the signal is strong in both houses and have tested the problem laptop in house 1 and the signal is strong but very weak in house 2. I have had the modem checked and all is working OK. I have had the wireless card in the problem laptop checked and it is working well off the premises. The only thing left to check is the electrical connect between the 2 house.
View 2 Replies View RelatedMy ISP (OTEnet, Greece) offers IPv6 connectivity in the form of dual-stack IPv4/IPv6 with the requirement that the router supports DHCPv6 Prefix Delegation for establishing an IPv6 connection.Using other routers (Cisco 887W, DrayTek Vigor2130n), I have established an IPv4/IPv6 connection but I am unable to do so with the EA4500. As a matter of fact, when I have the "IPv6 - Automatic" option enabled the router not only cannot obtain an IPv6 prefix from the ISP but it gets stuck in the connection attempt and never obtains an IPv4 or an IPv6 address. I have to disable the IPv6 option in order to simply establish an IPv4-only connection without problems.So, my questions are:
1. Does the latest (2.1.38.38880) firmware support dual-stack IPv6 and DHCPv6 Prefix Delegation?
2. If the router cannot negotiate an IPv6 connection why is it not establishing an IPv4 connection only but gets stuck in the process?

I'm trying to setup a router in my moms house. She has DSL and when the box is connected directly to her computer everything works fine. However, if I connect the router her computer reads "Limited or No Connectivity". I can connect to the router wired and wirelessly with my laptop, phone, and even her streaming media box without any problems. I ran IP config and i'm not geting a default gateway address.
