Belkin F5D7230-4 delay

Hi all -

Just got cable broadband access at this house, and got a Belkin
F5D7230-4 802.11g router to distribute things. From the get-go, there
was a delay in connections through the router, even on the wired ports.
With the computer connected directly to the modem, "ping google.com"
generates a response every second, as expected. Put the router in the
middle, and the pings are 5-6 seconds between results. The DNS
resolution is quick, but the actual traffic gets clogged up somewhere.
Other traffic (e.g., web surfing) is similarly delayed, typically when
loading the page initially.

The router was updated with the latest firmware (8.01.21), with no
apparent effect.

Suggestions?

Hmmm,
Maybe your ISP has not enough bandwidth. Try at different time of the
day. Don't blame the router.

I'd like to not blame the router, but it's pretty tightly linked. No
router, faster connection. Router in loop, connection delays. Take it
out, get the speed back.

It's been a consistent delay characteristic through the day/evening, on
all three machines tying in on the router (2 XP, 1 Linux).

It occurs to me that the router is doing NAT; perhaps that's a source
of delay, in setting up a new connection? Or the firewall
functionality, for that matter. It doesn't seem to be DNS, as that
resolution happens quickly.

Still hoping for a slam-dunk....

Hi,
Tried with only one computer hooked up at a time?

Yep. This was evident when I first plugged things in. I thought it to
be a misconfiguration (and it still could be), but it is slow on the
most basic situation: one computer connected via wire. And I did just
try with the firewall "disabled", no effect.

Check the cable, Woody

Maitland Florida? Road Runner?

What to do:
1. Take the router out of the picture and connect your PC directly to
the cable modem.
2. Run every diagnostic you can think of:
tracert ip_address_of_roadrunner_gateway
ping ip_address_of_roadrunner_gateway
tracert your_favorite_web_server
Look for where the latency increases.
3. Run
http://jlab4.jlab.org:7123/ (Virginia)
and any other online diagnostic and speed test. Are you getting
the advertised speeds?
4. Analyze the results and see if there's a pattern. If the delays
are always between you and RoadRunner, then you either have a broken
cable modem or RR has a problem.

If that looks good, then do it again with the router installed. Do it
from a wired ethernet connection to take wireless out of the picture.
The results should be identical. If not, then the router is broken.

Try it with wireless. The wireless should be faster than the RR
connection so the result should be about the same as with the wired
connection.

Incidentally, I spend about an hour troubleshooting a customer DSL
connection with erratic performance and flakey downloads. I
eventually found the miswired ethernet cable between the modem and
router. Make no assumptions and check everything.

Here be common problem of the marsupial creature which be looking like
big mouse/mini rat. Creature not so nice because he like eating ethernet
cable. Before cable fully broken by creature all strange faults present. I
be thinking it to do with the not match of the impedance and the wave
reflections which beget the errors.

You be checking your cables.

the assumption we are all making is that you are comparing like with like -
ie PC connected using Enet and Enet WAN between cable androuter.

If not, then could be other stuff.....

1. does the local LAN work reliably?

check ping etc to the router from the PC - if that is OK, then that
particular cable is OK there (although you may need a crossover / or not
between the router and WAN).

2. if the router lets you - run diags from the router interface, so you are
only testing the WAN.

FWIW some netgears will let you test DNS, use ping, and so on.

if all OK, then my guess is probably a config mismatch.

3. check the settings when cable is directly connected on the PC - MTU, IP,
DNS adr and all that.

then compare against the router. any differences then need looking at.

a UK cable modem site that may help (although no guarantee NTL / Telewest
use anything like your setup)

I'm sure I wasn't hallucinating, but the characteristics today are
different than yesterday. Back then, quick pings to yahoo.com without
router, slower pings with. Today, it's slow no matter the
configuration. Seems that some entity about five hops in (still in the
RR realm) introduces the delay.

Thanks for all the suggestions. The NW cables are all fine, reliable
comms, just a delay when establishing a network link. And when did
"traceroute" become "tracepath"?
