I am not quite sure what its the problem, my other guest the dont have the problem like I do they use Windows, and I use Linux.
I am losing network bandwidth and I am quite frankly I am not sure why, I don't have allot memory 495.6Mib But I clean my PC every few days "BleachBit"
Date.......CPU..........Network Receiving...........Sending
Oct/08.....12%.........313.5Mib.........................10.5Mib
Oct/12......47%.........0.0 Mib...........................0.0 Mib ..... ( I have Internet)
I have read some where on the magazine Network receiving suppose to be higher.
so how can I fix this issue please i am having allot problems, u use cable from Comcast
I am not quite sure what Information you might need from me to give.
Thank you very much
Note:
I use Ubuntu 8.04 LTS

guessing it's a glitch in firefox, try using opera, or perhaps tweak firefox with some different settings.
Do a search on the forums for "speed up firefox", that might help.

add to /etc/modprobe.d/modprobe.conf (or the appropraite distro specific translation)
| Code: | | alias net-pf-10 off |
that should cause a significant increase in speed.

I have try this........... before an my network still drop
Howto: Tweak and maximize your bandwidth in Ubuntu/Linux via sysctl!
Here I will unleash a few hidden settings that should improve your internet speed, and work with all current linux operating systems including Ubuntu:
| Quote: | | sudo gedit /etc/sysctl.conf |
Then Paste the Following at the end of the file:
## increase TCP max buffer size setable using setsockopt()
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216
## increase Linux autotuning TCP buffer limits
## min, default, and max number of bytes to use
## set max to at least 4MB, or higher if you use very high BDP paths
net.ipv4.tcp_rmem = 4096 87380 16777216
net.ipv4.tcp_wmem = 4096 65536 16777216
## don't cache ssthresh from previous connection
net.ipv4.tcp_no_metrics_save = 1
net.ipv4.tcp_moderate_rcvbuf = 1
## recommended to increase this for 1000 BT or higher
net.core.netdev_max_backlog = 2500
## for 10 GigE, use this, uncomment below
## net.core.netdev_max_backlog = 30000
## Turn off timestamps if you're on a gigabit or very busy network
## Having it off is one less thing the IP stack needs to work on
## net.ipv4.tcp_timestamps = 0
## disable tcp selective acknowledgements.
net.ipv4.tcp_sack = 0
##enable window scaling
net.ipv4.tcp_window_scaling = 1
Save and exit.
Type in terminal
to apply the settings.
You can disable all these settings by removing these lines you added via:
sudo gedit /etc/sysctl.conf

I still have this question:
| Quote: | Set the value of network.dns.disableIPv6 to "true" or false?
|
1. Type "about:config" in the adress field.
2. Set the value of network.http.pipelining to "true".
3. Set the value of network.http.pipelining.maxrequests to "100".
4. Set the value of network.http.proxy.pipelining to "true"
5. Set the value of nglayout.initialpaint.delay to "0"
6. Set the value of network.dns.disableIPv6 to "true"
7. Set the value of network.http.max-connections to "48"
8. Set the value of network.http.max-connections-per-server to "16"
9. Set the value of network.http.max-persistent-connections-per-proxy to "8"
10. Set the value of network.http.max-persistent-connections-per-server to "4"
