Hi,

I'm having problems with my DIR-628. It's new, I just bought it in late 2011.
I have the latest firmware version (1.24NA) and my hardware version is A2.

The wireless connection randomly drops out, and resetting the router (unplugging the power, waiting 15 seconds, then plugging it back in) only fixes it about half of the time. Connecting to it using an ethernet cable works fine! Sometimes, it won't even show up on the list of available connections even though the router is (literally) right beside my laptop!

It isn't my laptop (Macbook pro) because it happens with my roommate's computer as well.

I am in a dorm room at university so there would be a lot of interference due to lots of wireless routers. So, because of this, I've tried all the channels with no luck...still got the random drop outs.

My wireless settings are as follows:

Transmit power: High (I've tried medium and low too, but no change.)
Beacon period: 20
WLan Partition: unchecked
WMM Enable: checked
Short GI: checked (unchecking this doesn't stop the dropouts)

Wi-Fi protection is on (WEP2, I believe)

Secure spot is on.

The UDP and the TCP Endpoint Filtering settings are both set at 'Endpoint Independent'. Changing them around didn't seem to help.

There is nothing currently set on port forwarding.

Band: 2.40 GHz
Enable Auto channel scan: checked
- Tried all the channels with no improvement.

Wireless Radio : Enabled

802.11 Mode : Mixed 802.11n, 802.11g and 802.11b

Channel Width : 40MHz

Channel : 6

Secondary Channel : 2

Wi-Fi Protected Setup : Enabled/Configured

Advanced DNS: disabled

I checked the logs and nothing appeared out of the ordinary; just the usual 'blocked UDP/TCP from connecting' messages...I'm assuming SecureSpot is ensuring my router isn't hacked into?

The internet is really bad this morning too (numerous dropouts, dial-up speed) although it might be the university's problem and not my router.

That's all I can think of. If you guys need anymore information, just let me know!

Thanks in advance!

Is there and ISP modem or just a wall connection?

Some things to try:
Turn off ALL QoS or Disable Traffic Shaping (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.
Enable uPnP and Multi-cast Streaming under Advanced/Networking.


Try single mode G or mixed G and N?
Preferred security is WPA-Personal. WPA2/Auto TPIK and AES. Some WiFi adapters don't support AES, so you might want to try TPIK only.
If you have a lot of other Wifi in the area, this can cause the drop outs. Are they mostly 2.4Ghz? If so, you might want to change to a router that support 5Ghz. Or go wired.
The DIR-825 is a great router and has 5ghz.

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.
Turn off all devices accept for one wired PC while testing.

Check cable between Modem and Router, swap out to be sure. Cat6 is recommended.

I might try to upgrade to:
Firmware   1.25NA   12/28/2010

IF you do, please follow the FW update sticky process listed in this forum.

Let us know how it goes.

Hi,

It seems like all the settings you've suggested were already put in place by me before - probably when I was troubleshooting through another site.

Security is now set to WPA2.

I checked using KiSMac, and it looked like most people were on the 2.40 GHz, so I switched it to the 5.0 GHz. Let's see if that makes a difference...

I don't have access to the modem, as it belongs to the university, but the router is plugged into the wall.

Now it seems like my roommate can't connect - her laptop doesn't detect the router when I put it on the 5.0 GHz channel. It's running Windows 7 while I have a Macbook.

I'll let you know how things go - thanks!

[FurryNutz]

Her PC will need to support 5Ghz. Might need to upgrade her PC.

[SolitaryWolf]

The 5.0Ghz doesn't make a difference either - still random dropouts. I don't know what's going on, cause the router is LITERALLY right beside my laptop. So it can't be interference.

I feel like throwing it out the window!

[FurryNutz]

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

[FurryNutz]

Do you loose internet while wired connected to the router as a test?

I see that there is a more resent FW version however I don't think it might help, it could though:
Firmware   1.25NA   12/28/2010
Revision Info:   ¤ Removed Securespot Feature.

Could try this, if you do, please follow the FW update sticky process in this forum.
