NOTE: Little clarification, this is not needed at all ,as memory is freed when required.
WHY IT MAY BE HELP-FULL: This clears the page-cache , dentires and inodes.
IT’S TRANSLATION : It may be that you are watching a movie or using a Virtual Machine , a resource hungry process has filled up your ram by caching data and the data needs to be continuously removed to make space for new data . This is managed by the kernel.
IF YOU STILL DON’T GET IT: Notice video in your movie hanging (not audio) while your ram gets cached Or your system running a bit slow ?
1) Stop the process consuming loads of memory. (Check System Monitor).
2) Open a terminal with root privileges .
4) echo 3 > /proc/sys/vm/drop_caches
5) echo 0 > /proc/sys/vm/drop_caches
1) Find Vendor and ProdID
In the generated list where Manufacturer is ZTE , Incorporated
Take Vendor and ProdID
eg. Vendor=19d2 ProdID=fffd
-You can also use lsusb to get entry with ONDA Communication S.p.A in format a:b
2) Load Module
modprobe usbserial vendor=0x19d2 product=0xfffd
After this step 3 interfaces /dev/ttyUSB* where *(0-2)
should be created .(if not then rmmod usbserial ->remove device->modprobe again->insert device )
3)Configure (Run in root mode)(NOT FOR FEDORA go to 6)
Add number eg. #777
Add your username and password in the fields.
Ideally running wvdial should be enough.
ping google.com to check if you are connected)
6)However in fedora(and if above steps dont work for you) after modprobe
Go to System>Administration>Network>New>Modem>
In Modem Properties (Despite error)
change device to /dev/ttyUSB0
Phone number #777
Username and Password -as you have
Provider Name -any
Save And activate
Lets go back to the basics of IP addresses and their naming format.
An IP address is the unique identification code of a machine connected to a network (local or www)
The name eg.www.google.com is just an alias of the numeric ip addresses(here IPv4)
1)Windows -> Run ->cmd
1)Linux ->open terminal

I had been noticing for many months now that certain udf discs were not being mounted by fedora 8.
mount: block device /dev/sr0 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/sr0,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

Enabling wifi on Lenovo R60 AR5212 using madwifi-0.9.4.tar.gz :
Well i am sure everyone installed madwifi and it actually worked for some people ( see ankur‘s Directives ).
1)open terminal in su mode and enter directory where the madwifi-0.9.4.tar.gz has been extracted.
2)type ‘make’ press enter
3) type ‘make install’ press enter.
4)type ‘ modprobe ath_pci’ press enter.
Now here some people would have gotten “unable to insert module ….. no such device”
Heres what to be done :
1) go to /lib/modules/18.104.22.168-42.fc8/kernel/drivers/net/wireless/ath5k
2) rename ath5k.ko to ath5k.so.bkp (actually you can just delete it or blacklist it see comments)
3) go back to the madwifi directory to termianl
4)type “make uninstall ” press enter.
5)type “make clean” press enter.
7) Rename re-extract your madwifi-0.9.4.tar.gz to a different folder ( THIS ISNT NECCESSARY, BUT EVERYTIME I HAD TO DO THIS)
8) enter the new madwifi directory . Type “make clean “press enter.
9)type “make” press enter . type “make install ” enter.
10) type “modprobe ath_pci ” press enter.
NOW no new errors should come your network manager will now have wireless network selection.
!!!!!!!ENJOY!!!!!!! (PLZ COMMENT IF THIS METHOD WORKED FOR YOU OR NOT!!)
