I just got a DIR-655, and I got it working, with some effort. However, the wifi stops connecting to the internet every few hours and requires a reboot. Only a reboot of the wifi portion of the router's software, I go to Manual Wireless Connection Setup and save it without changing anything. LAN connections don't experience this.

Any idea what causes this?

Comcast Cable connection
DIR-655    
Hardware Version: B1   
Firmware Version: 2.00NA

Thanks!

What ISP Modem make and model do you have?

Some things to try:
Ensure DNS IP addresses are being filled in under Setup/Internet/Manual? You can find these under Status/Device Info/Wan section.
Turn off ALL QoS (DIR only) GameFuel (DGL only and if ON.) options. Advanced/QoS or Gamefuel.
Turn off Advanced DNS Services if you have this option under Setup/Internet/Manual.
Turn on DNS Relay under Setup/Networking.
Setup DHCP reserved IP addresses for all devices on the router. Setup/Networking
Ensure devices are set to auto obtain an IP address.
Set Firewall settings to Endpoint Independent for TCP and UDP under Advanced/Firewall if you have this option.

What wireless modes are you using?
Try single mode G or mixed G and N?
What security mode are you using? Preferred security is WPA-Personal. WPA2/Auto TPIK and AES.
What wireless devices do you have connected?
Any cordless house phones?
Any other WiFi routers in the area? Use InSSIDer to find out.
Turn off Short GI, WLAN Partiton and Extra Wireless Protection if you have it. Under Advanced/Advanced Wireless.

Turn off all anti virus and firewall programs on PC while testing. 3rd party firewalls are not generally needed when using routers as they are effective on blocking malicious inbound traffic.

DNS IP addresses are not filled in. They've defaulted to 75.75.75.75 and 75.75.76.76 for primary and secondary, respectively. What should these be? My ISP hasn't given me specific DNS addresses.

I've disabled QoS. Does it help meaningfully? It sounded nice, but I don't know that much about the technology involved.

I'm not using advanced DNS.

I've reserved all the addresses. That was probably a good idea in the first place.

Set devices to auto obtain IP on the devices, or is that a setting on the router somewhere?

I've changed the firewall settings. Out of curiosity, what did I just change? I've never really used a hardware firewall before.


My wireless mode is currently mixed g, n, and b. I'll try those if this fails again after the other changes. It takes several hours to get feedback on my changes, after all.

I'm using WPA-Personal, set to Auto TPIK and AES.

There are three or four computers and a handful of phones on the wifi at any given time.

We don't have any cordless phones.

There's about as much interference as there could possibly be from other WiFi routers, I'm set up in what is essentially a dorm at a tech school.

I've turned off Short GI. WLAN partition was off by default. I don't seem to have Extra Wireless Protection. What do these settings do? I'm sure I don't need to know, but I'm always curious what I'm changing when I change something like this.

Thanks!

Only way to find out what your ISP is send to the router would be to remove the 2 manual DNS entries, then reboot the router. After the reboot, go to the status/device info/wan section page on the router and look at the Primary and 2ndary DNS addresses there. If they are the same then you don't need to use the manual ones. The router can and will automatically use what it gets from the modem.

I've disabled QoS. Does it help meaningfully? It sounded nice, but I don't know that much about the technology involved.
If you don't do any gaming or streaming or have multiple computers all on at the same time streaming or something then QoS isn't really needed. If you game and such you can review the game, QoS and gamefuel sticky for XBL for some examples.

On the devices networking properties.

NAT Endpoint Filtering

The NAT Endpoint Filtering options control how the router's NAT manages incoming connection requests to ports that are already being used.
Endpoint Independent
Once a LAN-side application has created a connection through a specific port, the NAT will forward any incoming connection requests with the same port to the LAN-side application regardless of their origin. This is the least restrictive option, giving the best connectivity and allowing some applications (P2P applications in particular) to behave almost as if they are directly connected to the Internet.
Address Restricted
The NAT forwards incoming connection requests to a LAN-side host only when they come from the same IP address with which a connection was established. This allows the remote application to send data back through a port different from the one used when the outgoing session was created.
Port And Address Restricted
The NAT does not forward any incoming connection requests with the same port address as an already establish connection.

My wireless mode is currently mixed g, n, and b. I'll try those if this fails again after the other changes. It takes several hours to get feedback on my changes, after all.
I recommend changing to Single G or Mixed G and N. Most devices now days work on G mode at least and if your not using B mode then theres now real reason to broadcast that mode if it's not being used. It will also help the signal strength too.

Be aware that other WiFi routers in the area can effect how your routers Wifi performs. Channels are being used up and the routers are all having to scan and find a open one to maintain a good signal on.

Keep us posted on how it goes.

Yep, that's what I did.

I have three room-mates. All four of us are gamers.

Set devices to auto obtain IP on the devices, or is that a setting on the router somewhere?
On the devices networking properties.
Ok. It can't be anything to do with this, every single device goes down at once when it goes down.

I've changed the firewall settings. Out of curiosity, what did I just change? I've never really used a hardware firewall before.
NAT Endpoint Filtering
Okay. Good to know.

I recommend changing to Single G or Mixed G and N. Most devices now days work on G mode at least and if your not using B mode then theres now real reason to broadcast that mode if it's not being used. It will also help the signal strength too.
I can now verify that it goes down no matter the signal mode. I should clarify that this isn't an intermittent failure, the wireless is stable, consistent, and fast until it fails, and then it stays offline until I reboot the wireless hardware.

Be aware that other WiFi routers in the area can effect how your routers Wifi performs. Channels are being used up and the routers are all having to scan and find a open one to maintain a good signal on.
I'm aware of the possibility of interference, but I don't think this is the case. Prior to this, I was using a six-year-old USRobotics router with fruit punch spilled all over it. It never had any interference problems.

Keep us posted on how it goes.
I am still experiencing the same failure, regardless of wireless signal mode.

Well using a previous router probably was working up until punch got in the way however thats not to say that interference was not there either. Since then other WiFi routers could have been installed by your neighbors and thus adding more interference to your area.

Does this happen if all PCs are wired to the router?

I recommend wired for gaming, especially gaming, unless you can verify there isn't any external interferences or lots of other WiFi routers around, I wouldn't' game on WiFi, wired is best.

Maybe someone can review your router settings with you using teamviewer.

Also can try updating FW as well. Please review the FW update process sticky before updating.

That router still works, the punch didn't destroy it, just made me realize it was time for an upgrade anyway. It's not an interference problem.

It's only a problem with wireless connections. Wired connections are fine.

I'll try these.

[FurryNutz]

Also try setting a manual channel from Auto Scan. Find a open or clear channel thats not being used.

If the router is working via wired and the problems are wireless, then this is probably an interference issue.
Did you use InSSIDer to see now many other WiFi routers are near by?

Let us know how it goes.

bris,

Are your wireless devices still connected to the router, just not getting out to the internet?  Or do you lose connection to the router altogether?

I believe I've had both happen, but in general they lose connection to the internet, but not the router, I think.

[FurryNutz]

Any status on this?
