Hi. I'm at my wits end.
My original configuration:
I have a laptop (HP Pavillion dv9700). It comes with an integrated Intel
Wireless WiFi Link 4965AGN adapter and is running Vista Home Premium. I
have a D-Link DWL-2200AP wireless access point. I have an old Gateway
computer with a P3 processor running at 650 MHz and five NICs that was
running FreeBSD 7. I have a Westell DSL modem with 3000/768 service through
Verizon. The Gateway is set up as a firewall with ipf. The notebook
connects wirelessly to the WAP, which is cabled into a NIC in the firewall,
which is cabled to the DSL modem through a different NIC.
The problem:
I noticed that my wireless was running slowly. Verizon has a speed testing
website, so I test my speed with it. My upload speed nearly maxes out at
>700 Kbps no matter what my configuration is. My download speed doesn't
typically get above 90 Kbps. BUT, I have a PC running Windows XP Pro
connected to a third NIC in the firewall, and the speed test nearly maxes
out both upload and download speeds.
What I did:
Okay, something's wrong with the wireless link. I connect the WAP directly
to the DSL modem and retest my speed. I'm running at FULL speed, so the
problem isn't with the wireless connection between the laptop and the WAP.
So I reconnect the WAP to the firewall with a different (new, prefab,
unopened) ethernet cable and retest. Download speed sucks again; it's not a
cabling issue. So I move to a different NIC and retest. Download speed
still sucks; it's not the NIC. So I move to the NIC to which my XP PC was
connected (which got fast download speeds) and retested. Download speed
STILL sucks. I buy a D-Link DAP-1522 wireless access point and replace the
DWL-2200AP. I retest and get sucky download speeds. I've been wanting to
move to OpenBSD and pf for some time now, so I install OpenBSD 4.3 on the
firewall, set up my DSL connection, DNS service, and DHCP service. I
configure pf with a minimal configuration that basically lets all outbound
traffic pass and blocks all inbound traffic from the internet. I test
connectivity, and my Vista laptop and XP PC both connect to the Internet and
can talk to each other. The firewall can talk to everything. I put all
cables back to their original configuration; everything's connected as it
was when I first noticed the problem except for the new WAP, the new OS, and
the new cable. I retest my speeds. I'm back where I started: XP PC gets
full speed internet service, laptop gets sucky download speeds through the
wireless link. So with OpenBSD on the Gateway I retry everything I just
described above with the new WAP and new cable and get the same results. I
put everything back to the original configuration again except the WAP, OS,
and cable. I test the speed over the wireless link again and get sucky
download speeds. I copy a large file from my XP PC to my laptop (which is
still connected to the firewall wirelessly all this time) and I get GREAT
transfer speeds.
Conclusion:
So I can talk through my WAP and through my firewall to anything else on my
side of the internet connection at full speed, and everything that's not
wireless can talk through the firewall to the internet at full speed. But I
cannot talk through my WAP and through my firewall to the Internet at full
speed. I can talk through my WAP to the Internet (not through the firewall)
at full speed.
Can anyone please offer some assistance?
Thank you...
Additional information:
The three NICs in the firewall that I tried use the vr, xl, and ne drivers.
The vr has a VIA Rhine or RhineII chipset. The xl is a 3Com 3c905, and the
ne is a generic card using the Realtek 8029 chipset.
