Slow Speeds Using Wired Router Behind Router

[gbfitzger]

I'm seeing seriously degraded speeds when using a 3rd party router.

Setup is a Cisco E2000 running DD-WRT connected via ethernet cable to the outside unit.

When I connect wirelessly to the RG I see speed test from ~4-12 Mb.

However, if I connect the same machine a minute later to the 3rd party I consistantly see 2.5 Mb.  This is true if I use either a wireless connection or a wired connection to the 3rd party.

3rd Party WAN is setup to the public address via DHCP from RG

3rd Party LAN sitting on its own 192.168.2.x network serving DHCP

DMZplus mode is enabled on 2wire

Thoughts?

Has this been a problem from the start (has it ever worked correctly)?

Have you tried the Cisco with the stock firmware?

Have you re-flashed the ddwrt firmware?

You definately should not be seeing that kind of degradation. Either your missing a configuration setting in the RG/Cisco or there's a bug in the DDWRT.

I just re-flashed the E2000 back to stock Cisco firmware.

I then did a factory reset on the Uverse gear.

My only changes to the 2wire settings post reset were to:

-Enable ethernet port

-Enable DMZplus on the router MAC

My only changes to the E2000 were to:

-Change network address from 192.168.1.1 to 192.168.2.1

-Setup wireless

Same results on speed test....

Connected wirelessly to 2Wire 8 Mbps

Connected wirelessly to E2000 2.5 Mbps

Any ideas?

You might try to tweak the wireless settings (specifically the wireless channel) by using the techniques here:

Thanks for the tip. However, I have the issue whether using the wired interface off the router .... or wireless.

I dug out another old router WRT54GL using DD-WRT and otherwise used the same settings -- Voila, 12 Mbps speeds.

Looks like I'll be returning the E2000.

Thanks for your help.
