Strange speed problem with router

[ggadrian]

Hi,

I have a TP-Link tl-wr1043nd flashed with dd-wrt that I use connected to my internet carrier router (configured as a modem) because this way I get more options and, at least in my experience, more stability.

I changed my consumer-grade 10/0.8 ADSL for a business-grade 120/12 cable connection with guaranteed bandwidth and I got 2 problems:

-I'm only getting 80/13 mbps, but that's something that the carries has to fix, not me.
-Connected to my router, with the carrier router (CBN CG6640E) configured as a modem, I'm getting a lame 0'6/7Mbps connection.

Do you have any clues about what could be happening?

What is the speed of a PC plugged in thru ethernet directly to the carrier's modem/router? If your TP-Link is connect as a wireless bridge, your only going to get the throughput of that connection. I get 53mps connected to my suppliers modem configured as a router and only 23mbs connected to my Linksys WRT54G with dd-wrt connect as a wireless bridge.

I'm connecting everything using cat5e cable, so it isn't a Wi-Fi problem

Then reset the cable company's router back to it's defaults. Connect a cable from one of the ethernet ports to the LAN port of the DD-WRT modem. Configure the DD-WRT by turning off DHCP and pointing to the Cable company router as the gateway. Point your PC's connected to the DD-WRT to the cable company router as the DNS server and the gateway.

I had something similar I had to turn off Qos

Finally I had to go back to the stock firmware to make it work.

I'll try to turn-off the QoS and to put the modem as the gateway; I hope it works, because DD-WRT was much better than the original firmware.

Thanks

If I'm reading this right, your router may bottleneck your total bandwidth slightly. It is not the reason for the problem you are having, but still good to know if you want to take full advantage of what you are paying for.

Also what modem do you have...that could be a bottle neck as well.

I assume you are getting 80/13mbps when you are connected to the ISP's modem and when your computers connected with your TP-Link router speed reduces. So I believe the firmware you flashed is the culprit.

Finally I had to go back to the stock firmware to make it work.

Now how is the speed ? I recommend you to follow this thread for tweaking your computer to improve the connection speed.


If still issue exist, you really need to consider changing firmware.

Yes, it was a firmware problem, which is a shame because I really liked DD-WRT.

Now I'm getting the full 80/13, but using TP-Link's firmware.
