duplicate acks, no pl though. I think the duplicates may be my problem. If i crank up my send window, i get like 960 on the ndt tests, yet i cant go over around 70 KB/sec. Duplicate acks must slow it down.... so if i get it adjusted to where there aren't any dups, do you think it'll be faster?

[BAF]

hmm... the anl test under more details says: (the 5mbit test)

estimate = 3.1 based on packet size = 10Kbits, RTT = 145.87msec, and loss = 5.41419E-4

The theoretical network limit is 3.1 Mbps

The NDT server has a 8192.0 KByte buffer which limits the throughput to 438.74 Mbps

Your PC/Workstation has a 252.0 KByte buffer which limits the throughput to 13.49 Mbps

The network based flow control limits the throughput to 10.32 Mbps

Nitro gives me 3.08 dl and says:

estimate = 3.01 based on packet size = 11Kbits, RTT = 135.67msec, and loss = 7.45712E-4

The theoretical network limit is 3.01 Mbps

The NDT server has a 8192.0 KByte buffer which limits the throughput to 471.71 Mbps

Your PC/Workstation has a 250.0 KByte buffer which limits the throughput to 14.44 Mbps

The network based flow control limits the throughput to 10.75 Mbps

[VanBuren]

i dont really know how this packet reordering work, but i think your right you have alot of dup acks, and loss on the other test, make a traceroute and post it here

I have a fan blowing under my bed where the modem + linux firewall and my server are, as the modem + wireless router felt a little warm. I consistantly get 600 kbit upload (download needs to be retweaked i guess, 3-4 mbit) now that i have cool air blwoing on the stuff.... maybe it was too warm to do good or something.

thanks for the help so far.

Also, my network card is an integrated intel pro/e 100mbit card, on my asus p4p800... should I try putting a different card in? The WAN card in my firweall is integrated, and the lan card is a 3com 3c905b.

[VanBuren]

try this start-run-cmd

type ping -n 100 66.109.1.46 and hit enter

see if you have any loss, try both without network load and also while downloading

Also that has an additional 5 KB/sec upload, as my mom picked up the phone in the middle of the loaded ping test

and QoS/traffic shaper is off.

try another NIC, and see if it helps

it might have been loss just on the route to that testsite

You know, i've been thinking. I read somewhere that the 2.3.1.3 firmware for the sb5100 was buggy. I think it was that. I have that same firmware.... some bug about uploading. Come to think of it, i got ~200kbit on my 256kbb cap, ~400 on my 512kb cap, and now ~600 on the 920 kb cap.... i posted on dslreports.com.

My laptops upload (which is wireless) is only slightly better. prolly not the nic, aren't intel nics good?

[VanBuren]

Intels NIC

[BAF]

yeah, the only problem is a) i can get motorola's firmware, and i cant update it. For cable modems, the firmware is controlled by your isp. I would have to get adelphia to push the update :/

[VanBuren]

ask your ISP if you can lend a modem with a working firmware to test with

VanBuren

[BAF]

that's not so easy, i am 15 and i have to rely on my parents to do this stuff. they "dont know anything about this stuff" so they are hesitant to do anything

[VanBuren]

i understand, well you have very good speed even tho you dont max out, by now you probl know what settings that works best with your modem.

VanBuren

[BAF]

hanks... Ill let you know what comes out of my post about firmware on dslreports. A bunch of techs for adelphia read/post in the foruns, so maybe there has the power to get me a new firmware too.

[VanBuren]

good luck BAF
