Unable to wireless connect TP-Link TL-WR841ND to Motorola SBG900

G'day,

I have a Motorola SBG900 cable modem that offers wireless network, and I'm trying to get a TP-Link TL-WR841ND to connect to act as a bridge to the SBG900 wireless network.

The TP-Link finds my Motorola wireless network and appears to have no difficulty connecting to it (no errors reported when doing so) but when connecting the laptop to the LAN points on the TP-Link I have no internet access.

Info:
- My broadband cable entry is connected to the SBG900 (and works OK for the directly connected PC)
- I can connect OK to the SBG900 using a wireless laptop (and has full network connectivity)
- I believe I have correct WEP keys (to enable the TP-Link to connect to the Motorola SBG900 cable modem) configured (same wep key as the wireless laptop that connects OK)
- The laptop (Win XP Pro - SP2) has settings of "obtain IP auto" and "obtain DNS auto".
- There appears to be significant data passed between the laptop and the TP-Link (network connections see many Mbs of data transferred between them)
- I have updated the TP-Link to the latest firmware
SBG900 info:
WAN IP 60.224.128.48
LAN IP 192.168.0.1
WAN:
Static IP = 60.224.128.48
WAN default gateway = 60.224.128.1

TP-Link TL-WR841ND info:
Default IP = 192.168.1.1

Sorry to be a network newbie but it's frustrating me no end, so any help would be appreciated...

Cheers,
Andrew

  1. Try the ethernet cable, but also configure it manually by setting the gateway as 192.168.0.1 and the IP to 192.168.0.2
  2. Then enter normally and reconfigure it.
Optionally, try holding the reset button for 20s and access through wireless if you want.

The default username and password for most routers I have seen is admin and admin provided you have not changed it. All are lowercase letters.Also I suggest you use the WPA or WPA2+ encryption if its available. The WEP is easy to crack wirelessly and I had a gala time cracking my neighbor's router in less than 3 hours!

With that particular model you wont be able to use it as a wireless bridge. You can however run an ethernet cable from the modem to any point in your house. the SBG900 i believe has wireless built into it, so you may need up with 2 wireless networks.

Hope that helps.

Motorola SBG900 Assign network address to computer


I guess your modem router was already configured well since it worked already previously. It seems that your motorola router is set to broadcast dynamic IPs (DHCP enabled) and your last connected Pc and laptop were configured with static IP. Please check your "network connection" setting and make sure it is set to "Obtain IP automatically"

Bridging a Motorola SBG900 to a Speedstream 4200


You can't use the Motorola SBG900 for that. The only way it might work is if the Motorola SBG900 had a 4-port Ethernet switch built into it.

Can't connect to the internet wirelessly


Well, to avoid confusion, I'd start by doing a factory reset. Insert the straightened end of a paperclip into the reset hole and power up the device to do this. From there, the device should begin broadcasting the default wireless network with the name (SSID) of "Motorola." The DHCP server should also be enabled and if your computer is configured to receive an automatically assigned IP address your wireless network interface should pick up an IP. The security for the "Motorola" network is disabled by default.

Basic troubleshooting from there would be to try to see if you can connect your wireless computer to another wireless network that is know to be working well. Either buy and return another wireless access point or router from a retailer or head to a Starbucks or other establishment that offers free wireless. If the wireless computer is hooking up nicely with the secondary wireless network, you can refocus on the SBG900 as the likely source of the problem.

If after attempting the aforementioned procedures you find that the wireless computer continues to fail to connect to the SBG900 you might have to consider that you have a faulty device. At that point I would consider consulting the manufacturer's documentation.
