We decided to roll out a few mifi’s, and we did not like the fact they decide to go into tethering mode when plugged in, and not wifi. So I pulled one open, browsed settings and came up empty.
I backed up the configuration and looked through a few of the settings, and one stood out : routeroverusb, changed that from 0 to 1 and presto!
FIX :
1) Go to IE while connected via Wifi and not hooked up to USB, punch in your Mifi device IP (default 192.168.1.1)
2) In the top right, put in admin as the password (unless you changed it), and hit enter.
3) Click on Advanced > Config File
4) Back up the config file
5) Make a duplicate of that file, and open it up with wordpad/notepad (note MS WORD).
6) Find the line :
and change it to
7) Save the file, and go back and upload it.
While you are at it, boost the maximum transmit strength from 13 to 25. In the same configuration file, find the line
and change it to
I do not know where they came up with 25, but I wouldn’t try it myself, might drain the battery on the device more, or cause it to be unstable. I have not tested that.
Now, back in the web administration page, select the File, browse, and then upload file to add the new configuration file. Wait for the upload to complete, you will get a popup/progress bar. The device will then reboot itself. If it doesn’t hard shut it off yourself, and once it’s back running, hook up via wifi (not usb tethered yet), make sure it works, then plug it in.

This was a very simple mod, did not require anything, other then 4 new/shorter screws to replace the ones that were longer on the M4, and a bit of electrical tape. Without hte electrical tape, the drive was undetected, it was shorting out by touching the metal top…so there is a reason to the spacer :).
So far battery life has improved over the 320gb 7200rpm drive the x220 came with. I’d say a good 30 minutes over a usage. The battery still needs a bit of burn in though.

EDIT : Thanks to mark for commenting, you can get these screws :
“The screws are M2X3MM part #10124 from laptopscrews.com.”
I recently purchased an awesome little laptop…the Lenovo x220.
Specs :
Intel Core i7-2620M Processor (3.4GHz, 3MB L3, 1333MHz FSB) w/ USB3
Genuine Windows 7 Home Premium 64bit
12.5″ Premium (IPS) HD (1366×768) LED Backlit Display, Mobile Broadband Ready, 2×2 Antenna
IntelĀ® HD Graphics 3000
4 GB PC3-10600 DDR3 SDRAM 1333MHz SODIMM Memory (1 DIMM)
250 GB Hard Disk Drive, 5400rpm
ThinkPad Battery 29++ (9 cell)
Intel Centrino Advanced-N 6205 (2×2 AGN)
I decided I wanted to get an SSD, and opted for the Crucial M4 series. It required a little tweaking to get into the x220. I had to unscrew the middle spacer, and it slide right in.

These aren’t bad numbers at all, considering the manufacturer rates them at :
Sequential Access - Read
Up to 415 MB/s (SATA 6Gb/s)
Sequential Access - Write
Up to 175 MB/s (SATA 6Gb/s)
What I really like about this drive is the low power consumption, SATA 6/Gbp/s, as well as the 40,000 IOPS. I still think SSD’s are the number one upgrade for any PC (as long as they are SATA 3+ capable). They just make the system that much faster.
