I picked up an Asus RT-N66U to replace my WRT54G. I put Tomato (Shibby) on the RT-N66U.

The problem I'm having now is that I can connect to the router just fine, but I don't have internet access. Even though it's plugged into my cable modem (Cisco DPC3825) it doesn't seem to be getting an IP address or anything. If I pug in my old WRT54G then everything works fine.

When I plug in the RT-N66U to the cable modem the modem shows that the router is connected at 1Gps as the light on the front of he modem is green. However, there's just no internet access.

I ran into this very same problem when I upgraded to the RT-N16. The only way I got it to work was call my cable provider(Cox) and have them send a reset signal through to my cable modem. That seem to fix it and it worked great after that.

It ended up being a simple solution. I had to release the WAN MAC address from old router before I connected the new router. Once I did that, everything worked as it should.

So I'm slowly going insane. I have an asus RT-N56u and I'm getting intermittent wireless disconnects across all clients. If I have a continuous ping to the router going, I'll see spikes between 1 and 3 seconds of latency, packet loss, and pings will drop entirely sometimes. In the router logs, I'm getting the following message:
May 16 00:04:23 kernel: Qidx(1), not enough space in MgmtRing, MgmtRingFullCount=1!
May 16 00:04:23 kernel: Qidx(1), not enough space in MgmtRing, MgmtRingFullCount=2!

Google suggests a custom firmware by a gentleman named padavan, but this hasn't resolved my issue. I've also tried older firmware, and I'm currently running the latest firmware which is 3.0.4.360. I'm about ready to light this thing on fire and force everyone to deal with cat6 running through every doorway. Any thoughts would be much appreciated.

Did you do a factory reset after upgrading to Padavans firmware? I saw people complaining about that error when using stock firmware but never on Padawan firmware.

I think the hiccup I was seeing was just due to caching. The router would remember the PCs old IP and give it that, instead of assigning the new (reserved) IP. Once I got past that, everything worked absolutely perfectly.

My NIC would keep showing errors in event viewer when set to auto-negotiate for 1gbps, video streams would buffer occasionally as well. At 100full duplex it would be fine but the router showed a connecting at 100half. Since this only started when I moved the PC to a new room. Naturally, seven years ago when I punched down the RJ45 jack in this room I set it to 568a. The rest of the house is 568b. Durrrrrrrrrrrrrrrrrr. :downs:

The tricky thing may be home many neighbors are doing it. Realize that you have a connection to your neighbors past the breaker box. It is 'upstream' so it is more difficult to transmit OUT than in.

Not brand new, but not that old? No idea really. Can the neighbors cause interference or is it more of a security issue?

It has often been the case that the cable modem remembers the MAC address of the router to which it is connected. Rebooting the cable modem is a typical way to resolve this. You might just be able to unplug the cable modem momentarily.

At least this was the case with cable modems I've had and that relatives have had in various cities.

I should clarify, I wasn't seeing those errors in the logfile with Padavan's firmware, but I WAS seeing the same symptoms - short drops in wireless connectivity across multiple clients which coincided with massive latency spikes and packet loss to the router. I didn't factory reset after the firmware change, though, it set itself to default settings so I assumed it was good. I'll reload the firmware and try a reset. Thanks!

BEARD OF HAVOC

Having recently realized that my trusty 7+ year old WRT54GL is hindering full utilization of available resources by way of its 30mbit WAN port, I've decided it's probably a decent time to upgrade.

I've pretty much decided on the RT-N66U as it seems to be popular around here and elsewhere. The Tomato support certainly doesn't hurt, since that's what I've been using on the ol' Linksys and I'm quite comfy with it.

What about switches, though? I've got a couple 100mbit switches that I'd also like to replace with gigabit models, am I asking for trouble if I just pick up a couple cheap Rosewill or TP-Link models? Honestly, judging by newegg reviews it seems pretty tough to gently caress up a switch, but I thought I'd ask anyway.

Alright, more favors for family friends that have me running into brick walls and trying not to look totally incompetent.

Goal: Create a VPN that can be accessed by anybody from anywhere at anytime if they have proper credentials.

So my first attempt was to create a windows VPN setup on one of the computers.
I went->Network and Sharing Center->Change Adapter Settings->New Incoming Connection
In the dialogue:
I select a user "Guest"-> Check the box "through the internet"-> Check IPv4(IPv4 automatically assigns IP and allows caller to set their own IP), QOS and File Sharing. UN-check IPv6->Allow Access-> Computer name is "Home" and that's the end of the VPN setup dialogue giving me a new "incoming connections/no clients connected" icon in my network connections folder.

From there I go to the router and set port forwarding like so:

According to the HELP page for the router; Port 1723 is supposed to be the windows VPN. 192.168.1.69 is the internal IP of the "Home" computer that I configured the VPN on.

From here I boot up my laptop and using the wi-fi nextdoor try to use the "Create a VPN Connection" and punch in the external IP of the router for the network, destination name is "Home" because of that computer. I punch in the "Guest" and the password...

and nothing. Error 800. I'm assuming I'm doing something stupid with the port forwarding because its the only step that's not hand-holdy.

Any help would be appreciated, thank you very much.

So I have an Arris from TWC and an Apple Airport Express. I've just learned the hard way that the Apple Express cannot extend the signal from the Arris. Apparently the AE can only extend networks generated by other Apple products.

In any case, is there any workaround? What CAN I do with these two that might help with the range? Ugh...

I guess I can join the AE to the network generated by the Arris, which should help streaming to the media center in the living room.

e: Actually, would it be advisable to put the Arriss into Bridge mode, then route everything through the AE, which would be in a more central location?

It's confusing me because I have a game server running on that computer for a few friends, and for that I have an external port forwarded to the IP in question (192.168.1.200:7777) that works just great, so I know for certain that I'm not doing something stupid like trying to connect to the wrong IP.

Has anyone here using an Asus rt-n66u run into an issue with the wired connections acting like they are disabled after a device goes to sleep? I recently swapped out a dir-655 for the n66u and didn't change any settings on the computer. Every time I go back to the computer after its gone to sleep it reports the cable is disconnected. If I access the internet or the network it gives the error you'd expect if you weren't connected. After attempting that once, it will connect a few seconds later and everything works normally. This never happened with the 655. Am i missing a setting somewhere in the router that's causing this behavior?

Unless you have a lot of interference on 2.4ghz in your area that's causing problems, 5ghz tends not to get as good a signal unless you are sitting pretty close to it. Shorter range and worse at penetrating walls etc. I like it for stationary applications like bridging where I know the signal strength is always going to be the same and things can run at N speeds since there aren't generally any legacy devices on a 5ghz network.

I have that wireless card and it's great. I don't do any multiplayer PC gaming but in my web browsing I have not noticed any drop outs. I have it connected to a Netgear WNDR4000 at 5GHZ 3 channel mode (450Mbps) and can hit 100mbit (my connections speed) on speedtests and usenet which is why I spent so much money in the first place :).

According to Google Maps I'm about 5m (16ft) away from the router with the signal passing between 2 interior house walls.

It also worked straight away in Windows 8 without installing any drivers which was nice.

I've been using one of these for about a year and I really like the stable 5ghz connection I receive from it, and I can maintain a surprisingly low ping (and consistently max out my connection - up to ~80mbit) with this wireless card which is nice for online gaming. I use the drivers directly from atheros.cz (AR9380 - these are WHQL drivers so Windows Update will have them as well), so I don't know if the TP-Link driver set is any good or not, but I haven't had any complaints with this one. The stock antennas work well enough through 2 walls and roughly 16-17' that I haven't bothered looking into replacements.


That said, I'd get a dual-band Centrino for desktops kit if I was buying new, since it wasn't available last year when I bought this card. I haven't used one personally so I couldn't comment on performance, but Intel wireless chipsets are generally high-quality parts.

I just picked up the 6235 for my laptop since the included Atheros 9485 would crap on itself every time I tried to transfer more than a gigabyte or two wirelessly. So far I'm loving it.

I'm trying to fragment my network right now so that only PCs physically wired to it can access shared files/the server, while wireless clients only get internet.

My setup so far had been as follows.

Modem -> Linksys WRT54G2 -> various devices (wired and wireless)

What I've done right now is turn off wireless access on the WRT54G and plugged in a separate router into one of the WRT54Gs ports (using the second router's WAN port), set it on a different subnet (eg: the WRT54G is 192.168.1.1, and the new router is 192.168.2.1), and let that second router hand out IPs on its own subnet.

So now it goes: Modem -> Linksys WRT54G2 -> wired devices -> generic router on different subnet -> wireless devices.

This apparently works. I get internet on all wireless devices but they don't see any of the wired devices (at least from Windows).

Is this enough, or will someone with a minimum of networking skills be able to bypass that limitation?

Is there any "correct" way of doing this?

Two ways I have done this:

1) with broadband where I have more than one public IP, just put the wireless network on its own public IP/different router and enable ap isolation if I don't even want the wireless clients to talk to each other. Run the wired/private wireless network on another router/IP.

2) with the 'guest network' feature on newer apple routers

I think your way is kind of hacky and will lead to double NAT problems (which might not matter) on the wireless network, but maybe it works?

This won't block IP traffic to the wired devices network unless you add some IP tables rules such that the "generic router" doesn't allow it's devices to talk to any of the local (RFC 1918) networks.

In a setup like that, you could be able to ping a wired device from one of your wireless devices unless there is something on the generic router blocking the packets.

Is there any way to do this via protocol blocking? The router has a few options regarding that.

Worst comes to worst, I don't have much of a problem with getting a better router that could do this. In fact, I originally was going to buy a Linksys E900 and set it on Bridge-Repeater mode, but just as I was to buy it I found the old generic router (it's an Encore ENHWI-G3, in case anyone was wondering) and decided to see if I could save myself a few bucks.

I recently purchased an ASUS RT-N66R (same as the N66U) to replace my current router which has had DD-WRT on it for the last few years. After some research I can't seem to find any concrete guides for installing builds of DD-WRT onto the N66 without it breaking something/bricking it. Tomato seems to lack information as well. It seems like the best option is the ASUS-Merlin firmware. Does anyone have any recommendations/advice/experience on which third-party firmware works well with this router? Should I avoid DD-WRT or Tomato entirely?

This is totally quick and dirty, but here are my procedure notes from when I first tackled getting dd-wrt on the N66U. I'm happy to provide more detail/clarification on any part of the process. I've done five so far.

Note to Ur Getting Fatter: The last half of this procedure was to get a guest wireless network with total isolation from anything except internet access. You might find something helpful in using iptables rather than a two router solution, for the reasons Dogen listed.

5) Waited 10 minutes after the 'Please reboot manually' prompt, finally pressed power button

6) Ping and GUI finally came up after seeing dd-wrt SSID appear

7) Performed 30-30-30 reset using WPS button as suggested

8) Set up regular wireless and then began VAP config as per guide http://www.dd-wrt.com/wiki/index.php/Multiple_WLANs

a) Go Wireless -> Basic Settings and under Virtual Interfaces press Add. Turn AP Isolation On and leave it Bridged, press APPLY, test DHCP join and net access

b) Put on encryption, test DHCP and net access again

c) Separate the WLANs: Go Setup -> Networking and press Add under Create Bridge. Type "br1" and press APPLY. (This creates br1 under br0 which pre-exists)

d) IP boxes appear. Give new subnet IP of 192.168.x.1 with mask 255.255.255.0. Press APPLY.

e) In Assign to Bridge section, go to left dropdown and pick "br1" and "wl0.1" on the right. Press APPLY.

f) In Muliple DHCP Server section, press Add, then pick "br1" from the dropdown. Press APPLY.

g) Test DHCP and verify subnet address assignment.

h) This is a build greater than 17000 series, so must add iptables commands to get net access. Go Administration -> Commands ad add the following commands:

iptables -t nat -I POSTROUTING -o `get_wanface` -j SNAT --to `nvram get wan_ipaddr`
iptables -I FORWARD -i br1 -o br0 -m state --state NEW -j DROP

{Notes:}
{first line=Enable NAT on the WAN port to correct a bug in builds over 17000}
{second line=restricts br1 from accessing br0}

i) Press Add Firewall and reboot.. That should do it.
