  I have had a very stable wifi with my 615 for the last year. No problems with my desktop (Vista) or laptop (Vista) or other comp(XP). Just purchased a new laptop (Windows 7) which knocks out my wifi every 5-10 minutes. Cycle power and back up she comes. Now its to the point that when sometime when the wifi goes down..it also knocks out my hard line connection. This is also corrected with a power cycle. I've tried every "tip" I could find through Google (channel 11, only wpa-only, 802.11n only,etc.)and updated the firmware to "Current Firmware Version : 2.25  Current Firmware Date : 2008/05/16 "
 Again...this problem only reared it's ugly head when I brought the Windows 7 OS into the mix. It seems like its could be related to uploads as it drops my wifi while sending emails or posting. I've also noticed a drop in my upload speed (speedtest) from my hard line comp.
 DIR-615 B2
 
 Any thoughts other then a trip to Best Buy??

 Almost forgot. Son's new Windows 7 comp causes same issue. And..I can stream Pandora all day without a problem with my tablet but as soon as a Windows 7 comp connects, the crashes begin.

 Thx

Link>Welcome!
What Hardware version is your router? Look at sticker under router.
Link>What Firmware version is currently loaded? Found on routers web page under status.
What region are you located?

What ISP Service do you have? Cable or DSL?
What ISP Modem do you have? Stand Alone or built in router?
What ISP Modem make and model do you have?
If this modem has a built in router, it's best to bridge the modem. Having 2 routers on the same line can cause connection problems.
To tell if the modem is bridged or not, look at the routers web page, Status/Device Info/Wan Section, if there is a 192.168.0.# address in the WAN IP address field, then the modem is not bridged.
If the modem can't be bridged then see if the modem has a DMZ option and input the IP address the router gets from the modem and put that into the modems DMZ.

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.

Link>Wireless Installation Considerations
What wireless modes are you using? Under Setup/Wireless/Manual.
Try single mode G or N or mixed G and N?
Channel Width set for Auto 20/40Mhz or try 20Mhz only.
Try setting a manual channel to a open or unused channel.
What security mode are you using? Preferred security is WPA-Personal. WPA2/AES Only. Some WiFi adapters don't support AES, so you might want to try TPIK only or Auto.
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 WISH, and WPS under Advanced.
Try turning off Short GI, WLAN Partition,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.
Turn off all devices accept for one wired PC while testing.

 I've seen your pasted post already in many locations throughout this forum. I'll just run to Best Buy and end this madness.
