D-Link DSL Modem/Routers => DSL-2740B => Topic started by: cyberbeast on January 13, 2014, 10:52:03 AM

I have the following router at home:
Product: DSL-2740B, Firmware Version: 2.61 Hardware Version: C2
I've had some problems lately: connection dropping, wireless is very unreliable.
I thought about upgrading the firmware but I don't know which I should use.
On the belgian site, my hardware revision (C2) is not listed.
There are a lot of firmwares floating around on the internet and I don't know which one to choose. I don't want to ruin my router.
Can someone provide me or give me a link to the correct and most recent firmware?

Why don't we do some troubleshooting before attempting a FW update as it might not resolve anything.
- What region are you located?
- Are you wired or wireless connected to the router?
- What ISP Modem service link speeds UP and Down do you have?
- Check ISP MTU requirements, Cable is usually 1500, DSL is around 1492 down to 1472. Call the ISP and ask. Link>Checking MTU Values (http://forums.dlink.com/index.php?topic=53008.0)
- For DSL/PPPoE connections on the router, ensure that "Always ON" option is enabled.
I recommend that you have your ISP check the phone cabling going to the ISP modem, check signal levels going to the ISP modem. Check for t.v. line splitters and remove them as they can introduce noise on the line and lower the signal going to the ISP modem. The modem operation is dependent upon getting good data flow from the ISP Service.

- Ensure the default (dlink) SSID name is changed. Can be anything and not something thats already in use by any neighboring WiFi routers. Under Setup/Wireless/Manual.
- What wireless modes are you using?
- 2.4Ghz Routers only: 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 (http://en.wikipedia.org/wiki/Wireless_channel) to a open or unused channel. 1, 6 or 11. 11 for single mode N if the channel is clear.
- What security mode are you using? Preferred security is WPA-Personal. WPA2/AES Only. Some WiFi adapters don't support AES (http://en.wikipedia.org/wiki/Advanced_Encryption_Standard), so you might want to try TPIK (http://en.wikipedia.org/wiki/Temporal_Key_Integrity_Protocol) only or Auto TPIK and AES.
- What wireless devices do you have connected?
- Any cordless house phones?
- Any other WiFi routers in the area? Link> Use InSSIDer (http://www.metageek.net/) to find out. How many?
- If you have any of these options, Try turning OFF or ON Short GI (http://www.smallnetbuilder.com/wireless/wireless-features/30969-what-do-80211ns-optional-features-mean-for-you), WLAN Partition, HT 20/40 Co-exhistance and Extra Wireless Protection if you have it. Recommended settings are default. Under Advanced/Advanced Wireless.
- Enable WMM Enable (http://forums.dlink.com/index.php?topic=50738.0) Under Advanced/Advanced Wireless.
- Try setting Medium or Low power output settings and test again Under Advanced/Advanced Wireless.
Router Placement
Forum User - "Well I feel really dumb. After moving the router away from other electronic devices my speeds are back to normal. Just a heads up for anyone experiencing slow speeds, you might want to move it away from other electronics and see if that helps."
6" minimum safe distance between devices.
3rd Party Security Software Configurations
- 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 LAN PC while testing.
- Disable any downloading client software managers, i.e. Torrents or similar.

Any status on this? ???
