Help with unknown IP address in tracert

[NastySquared]

Any help is appreciated...

I've been experiencing slowdowns intermittently with my internet connection.
I have DSL with a static IP address

Routing through a Linksys WRT54G with DD-WRT v24

When doing a tracert from my computer the log is as follows

Tracing route to www-real.wa1.b.yahoo.com [69.147.76.15]
over a maximum of 30 hops:

What I don't understand is the second hop. Why would a 192.168.XX.XX address be AFTER the hop to my router? I even plugged the modem directly into my router and it still hopped to the 192.168.254.1 before going out to my net provider.

I contacted them and they claim to now know what that address is and they don't have any network devices with 192.168.XX.XX address

Sounds like your modem is handling PPPoE duties. I imagine if you offloaded the PPPoE settings to your router, you'd lose that extra hop. 192.168.xx.xx addresses are reserved for private networks if I recall correctly.

44ms is negligible taking into consideration the rest of the timimgs.

A lot of times a provider will use private address for their internal transport network.

I was under the impression PPPoE required a username / password (which my provider doesn't require) and when I click the DD-WRT settings for PPPoE it asks me for them and doesn't have a place for me to enter my static IP address

Yes, 44ms is negligible but when the internet slows to a crawl the hop AFTER 19.168.1.1 to 192.168.254.1 is in the range of 1000ms

Makes sense but wouldn't they be aware of this and be able to let us know why we're seeing this IP address in the tracert (of course... it is tech support, and often I think they just say stuff to end a call quickly)
