Linksys Wireless Router :: EA4500 Prefix Delegation For Establishing An IPv6 Connection
Aug 30, 2012
My 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 noticed that the recently released firmware version 1.2.0.9 for the RV110W router mentions in the release notes that DHCPv6 Prefix Delegation is now supported.
Does that mean that this feature will also be implemented in some future firmware release (if we ever see one) for the RV220W router? This is the method used by most if not all ISPs around the world (e.g. Comcast) for IPv6 and the only one RV220W does not currently support. P.S. As of beta version 1.0.4.13 there is no support for IPv6 Prefix Delegation.

I am struggling turning on DHCP client prefix delegation on a dial 0 interface on at 1941w.
Everything can be configured apart from prefix delegation features. The following command is just are missing.
int dial 0
ipv6 dhcp client pb
I have configured this on a 877 router with no problems. I have tried 15.0(1)M3 and 15.1(3)T.

I am trying to configure this router to obtain an IPv6 address from my ISP who offers a dual stack IPv4/IPv6 DHCPv6 Prefix Delegation service.
I did a WAN packet capture to see the type of DHCPv6 packets the router sends to the ISP in order to obtain an IPv6 address and I saw that the router is sending DHCPv6 solicitation packets of type IA_NA i.e. for Identity Association for Non-temporary Address. However, most ISPs that offer a dual stack IP4/IPv6 service, they use DHCPv6 Prefix Delegation in which case the router is expected to send DHCPv6 solicitation packets of type IA_PD i.e. for Identity Association for Prefix Delegation.
I then downloaded its configuration file and saw the following:
dhcpv6c = {}
dhcpv6c[1] = {}
dhcpv6c[1]["renewTime"] = "3600"
[Code].....
So, the option for the DHCPv6 client to perform a prefixDelegation request is disabled. Does that mean that if I set this flag to "1" it is going to work? Well, I edited the configuration file and changed this flag but the router refuses to load it! It complains about the file being changed. How does it know that? Is it computing some type of checksum? How can I manually edit this flag and update the router's configuration?

Since this router already set up for IPv6 and Dual-Stack traffic, would it be possible to give it the ability to get its IPv6 prefix from the WAN side of the router.
Example:
I have Comcast, and as long as my modem and router support IPv6, with the router also supporting DHCPv6-PD to get the /64 prefix from comcast.
I now have an RV180W so this is not an issue for me, but my father is inheriting the WRVS4400N from me and he is also on Comcast.

Lets get this straight, right off! If I plugged my computer directly to my Comcast Modem, IPv6 works fine on the { url } So I do not think any of this problem is related to my computer
I bought a EA4500 Router so I would be ready for IPv6, and also wanted N as well as the storage USB port. When I got the router, it came I guess with the original release firmware. It looked "Classic", but the box said Smart. I did the firmware upgrade. I could not get a IPv6 from Comcast. IPv4 worked fine.
I then changed to the latest "Classic: firmware, and all started to work. So I decided to try Smart again. Same thing, no IPv6 from Comcast. After being on chat for I think close to 2 hours today and getting no where, I did a reset to start at scratch again. I then got a IPv6 from Comcast. Many moons ago, it was a real hassle to switch devices hooked to a cable modem. At least here you had to power cycle the modem, so I have always cloned my wired Desktop MAC. So when I put it back in, I lost IPv6 from Comcast. Turned off MAC cloning, and I got the IPv6 again. So it looks like there is a bug in the Smart Firmware and MAC cloning since it worked OK with Classic firmware. OK, I could live with no cloning since the issues of yesteryear don't seem to be there in getting a IP from the cable modem.
Then for what ever reason, my computer would not get a valid IPv6 on the LAN from the router. I got some IP, but no Gateway. I tried everything I could think off. And again, plugging the computer directly to the cable modem, IPv6 worked fine. So something is just not right with this router as far as I am concerned.
Also, it seems like navigating through the menus on a local connection (192.168.1.1), I constantly got a message to wait popping up on the screen, for many seconds. If I had no Internet connection it would take forever on some things.
I have spent many hours on this, and am just giving up and going to look at another brand product. I don't need or want the "Smart" functions anyway.

No changes made but router will lose all information for IPv connectivity. I have paid twice to support to fix this issue and it still occurs every few months. I tried rebooting router, and doing an IP Release/ Renew and router does not get IP address.

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.

We have been testing out IPv6 configurations on a 5520 running 8.2(4). We have assigned EUI-64 prefix addresses to sub-interfaces to allow clients to auto-configure there IPv6 IPs and it works correctly. I used ASDM to do the original configuration and noticed that there were two different ways to do it, both of which seem to work. I can add a prefix under the Interface IPv6 Addresses dialog box and check EUI64 or I can add it under the Interface IPv6 Prefixes. But using the two methods yields two different interface configurations:
1.
interface GigabitEthernet0/1.40
vlan 40
nameif test
[Code].....

I had a WRT54G2 router and began having trouble with my PS3. It would connect for a few minutes then it would lose the internet connection. I thought maybe it was the router so I have the EA4500 now. The same problem is still happening. I connected all of my other wireless devices to the EA4500 with no problems. The PS3 connects and signs me in and then two or three minutes I'm disconnected. I called Sony and Cisco for assistance but in vain. The PS3 is showing my network has nearly 100% signal strength so that isn't a problem

I have 100 mbps fiber connection. I bought 320N today I bought 320N and here is the problem:
We have a switch in the building. I am getting connection via CAT5. So I choosed "Use as WAN Port" from Ethernet settings. There is not much you can do here. I just used PPPoE and connected internet without any problem. The problem is I am only getting 32mbps. When I connect CAT5 cable directly to my computer I am getting 92mbps.
Maybe WAG320N is not establishing a full duplex connection.

Just installed a refurb EA4500 this past weekend after testing it for a week. The regular wireless network is very stable, but not much faster than my single-band DLink DIR655. Guest network seems to drop out from two connected iPhones, and when the connection drops, you have to re-login and type in the guest password everytime. The linksys firmware is up-to-date( Linksys smart wifi)and so are the iOS on the 2 iPhones. Just to add, on my old DLink, the guest network comes up secured also, so when you type in the passcode, it remembers it next it comes in range unlike the Cisco, which requires login at a web interface.

I have a Cisco EA4500 wireless router. The only issue I have had with this router is when power gets disconnected or if I have a power outage, I have to go through some loops to get it to work again usually taking upwards of 45 minutes to fix.

I have a problem with my new router. I connected't my iMac (27" 2010) and NAS Synology 1511. My problem is the slow connection between mac and router - only 100Mbit (ethernet port on mac is 1Gbit), strange thing... my NAS have 1Gbit with no problem, and the mac is not. I trying manual configure - forcing speed to 1Gbit, but then is no connection at all. I'm also trying changing wires, but no change. Im buying special ethernet cable cat 6 - also no change. Changing ports on router - result the same.

I recently upgraded my Wild blue internet service to the "Exede" system. When I kept losing the connection to my Mac Air book, the Wild blue service tech suggested that my wireless router (Linksys Wireless G 2.4 GHz router) was not robust enough to handle the increased "speed". They recommended I purchase a new router so I purchased the Linksys EA4500.
Now, after three weeks, the Linksys EA4500 router has stopped working. I am able to hook one of our Mac Books directly to the satellite modem to access the internet through an Ethernet connection. Finally, I finally reconnected my old Linksys Wireless G router to the modem to check to see if it would work and it does.
So, I'm wondering about the failure rate of the new Linksys EA4500 routers? Is there anything else I might try to get my new router to work??? I have unplugged it for an hour and then re connected it. I have pushed the reset button..My wireless indicator on the Mac Book Air shows full signal strength, but I can't connect to the internet with my new (less than 3 weeks old) router.

Purchased an EA4500 router. I'm using an old HP 4L laserjet and have it connected to the router via the USB port. I have 2 Mac's and installed vusb on both. I can successfully print from both Mac's, however I have to manually disconnect and connect the printer in the vusb client. I can't get the auto-connect and auto-disconnect settings to work by themselves. Any guidance on the proper settings here?Additionally, do I need to configure the printer driver though the vusb client? When I click "configure", I get an error saying"Cannot connect to Prolific Technology Inc. IEEE-1284 Controller.

My EA4500 router seems to drop mine and my wife's iPhone wifi connection at what appears to be the edge of my router's range. When we come back in range, our iPhone's intermittently give the error "Unable to join network.". And we're stuck in that mode. When I check the Devices menu in the CCC interface, I notice the iPhone device is configured and still online. However the "x" box to delete the device is greyed out because it's online. So how do I get out of this state and have my iPhone connect

I set up my new EA4500 last night, and configured the 5Ghz and 2.4Ghz bands with separate SSIDs (as recommended). While I can see the 2.4Ghz band with all of my devices, I cannot see the 5Ghz band with any of them.I followed the advice given (including the settings shown) on the EA4500 FAQ.Title: Personalizing and connecting to the 5 GHz wireless band on a Linksys Wireless-N routerArticle ID: 21466.Did that *multiple* times, and still nothing. I do have a dual-band capable adapter (Netgear RangeMax WNDA3100 Dual Band Wireless-N Adapter) that I know works on 5Ghz (because I had it working on my old dual-band WDNR3700v1). Similarly, I have PCs sitting less than 20 feet away that were previously able to see the 5Ghz band on my old router, but are now unable to see it on the EA4500.

I've set up PPPoE on my EA4500 router with a Vigor 120 modem in bridged mode and it says an internet connection is established, but the connection is extremely slow on all my devices. When I run the speed test within the EA4500 firmware it appears fine, but I cannot load any web pages on my laptop or other decives because the connection is so slow. The connection is slow with both wired and wireless connections. I've tried changing the MTU settings with no success. I've also tried using a different router and connecting the modem directly to my laptop and using PPPoE within the laptop and these both work fine, so I think it's clear there is a problem with the EA4500 router itself.
I'm just using the Vigor 120 to authenticate and connect to the internet itself, with the router in DHCP automatic configuration mode. I think this is causing a double NAT.

I have an e4200 V1 with firmeare V 1.0.04 For my IPv4 configuration I use opendns.com for my DNS provider.When I enable IPv6, I get my ISPs DNS server rather than the one I have configured on the IPv4 page. It works, but it eliminates all filtering and statistics that I am able to do with opendns.com.Open DNS does provide two IPv6 DNS servers, but I don't seem to be able to find where to set them in my e4200. I want it set network wide.Can I set my IPv6 DNS provider anywhere in the e4200v1 with V 1.0.04?

Our internet provider has no intention of providing a IPv6 DNS so I have a crippled at best service. We live in an area where our only option is through satellite service, so changing providers in not in the cards, yet.
If I "Disable" the DHCP Sever, the setup menu provides a method for me to force feed up to three Static DNS addresses, all with IPv4 addresses.
There are several locations that provide "free" DNS service, but how does one verify the security of such sites? Does Cisco keep track of the status of this kind of service or am I on my own? Cisco seems to endorse two DDNS services, but for home use, the extra charges seem otherwise unnecessary, and do not yet address the IPv6 question.
The first few that I have investigated that do provide IPv6 service also provide their addresses in IPv6 format. The E4200 menu does not seem to allow me to do that.
Am I going to be forced to live with crippled IPv6? I have already discovered a software product that has failed since changing routers, but works if I take my laptop to a particular WiFi location.

So I've realized that my parental controls were being ignored by the computers, at first I figured my son had found a work around to by-pass. But reading through the forums today, I've found that IPv6 being enabled might be the cause of my issue. So I'm currently sitting at work and connected to my router remotely, but for the life of me, can't see where to disable this option. Using the Smart Wi-Fi interface, closest I can get is "Connectivity, Internet Settings, IPv6 but everything is grayed out and no option to edit this.

IPV4 IP addresses will be running out in less than a year and I wanted to know, will there be a firmware update for WRT120N to support IPV6?
Also, if I have to buy another router to support IPV6, I'm going to buy a D-Link. It's nothing personal, I just find it absolutely idiotic that a router that supports wireless-N doesn't support IPV6. You have to ask your self, how does the standard IPV6 spec thats a few years old not make it to the final product of a router, but a non-standard wireless-N spec implementation somehow got the O.K....?

I have my router updated with the latest firmware and I'm pretty sure all the settings are correct but I'm only getting a max transfer rate of 144Mbps. I know this because I use InSSIDer 3 to analyse my wifi network etc. I stream movies over my network and while DVD quality movies play fine, HD movies tend to freeze and buffer a lot. I have the router's channel width set to 40Mhz, so I know that's not the problem. Strangely, I also use a Netgear wifi extender with the MR3420 and it's max rate is 300Mbps.
