Google Chrome RWIN

31 May 2011 - 02:35 PM

Is it possible to change the RWIN of google chrome?  Both internet explorer and firefox use the 256960 (MSS * 44 * 2^2) which I set but chrome uses its own RWIN of 65536 for some reason.

Home Networking dilemma

20 April 2009 - 09:46 PM

Well I have this networking problem that I just can't put my finger on.  As I was making this picture I came up with an Idea.  I hope you will too.  Computer "B" can ping my network but no one in the network can ping computer B. (Just keeping it abstract here) All connections are physical Cat5 cable.

RR Boost on non-Turbo plan?

...it's still horrible miserable.. at least here in San Diego North County.. horrible miserable loss, ping... and speeds are miserable... 3900/384, adn the TV parts has problems as well. Maybe the res tof you have had service increases, we are getting screwed badly in my area..

For the last half of 2008 both my timewarner internet and TV were horrible.  No internet for as much as 2 days every month, and the packet loss on the TV made it unwatchable.  Today, I almost mistook my download speed for my LAN speed.  In this picture you can see what appears to be speedboost on my 10mbps RR service plan.

Download Connection is:: 11998 Kbps about 12 Mbps (tested with 51195 kB)
Download Speed is:: 1465 kB/s
Bottom Line:: 209X faster than 56K 1MB Download in 0.7 sec
Tested from a 51195 kB file and took 34.954 seconds to complete
Download Diagnosis:: Awesome! 20% + : 123.84 % faster than the average for host (rr.com)

In case your wondering this is San Diego.

Ram Upgrade on a HP

07 January 2009 - 11:21 AM

My pavillion a1524n came with 1 GB of samsung DDR2 PC-4200 and one open slot for another stick.  So I bought Corsair 1GB DDR2 PC-4200 to add in.  (Part # VS1GB533D2)  The Samsung works in slot 1 and slot 2.  The Corsair works in slot 1 and slot 2.  But If I put them both in at the same time bios says slot 2 is empty no matter the combination.  The board is rated by HP for 2 x 1GB of ram.   I'm wondering if the HP motherboard has some weird setting preventing this from working or if it's proprietary.  Your thoughts?

Help (packet loss?)

27 September 2008 - 12:34 PM

All computers in the house are suffering from terrable download speeds.  Download tests show frequent pauses between bursts of good speed which point to packet loss.  Restarting the modem and router have no effect.  PunkBuster also kicked me for "loosing key packets."  The average ping to a variety of websites is 60-100ms (which is good).
