dr.faramroze posted a topic in Tutorial and GuidesVerizon's Novatel, ZTE and Pantech pocket routers are very popular in US. Initially, Novatel 2200 Jetpacks were based on NV mode programming only. Now the newer Novatel 4510, 4620L, 4620LE and 5510 are based on CDMA SIM slots. The ZTE 890L and Novatel 4620L/LE are global mode MiFi devices where any GSM SIM will work on the go. While Reliance 1x works instantly upon SIM insertion, Evdo does not connect and needs to be tweaked a little. And data on Tata Indicom does not work without these tweaks. Requirements for Reliance CDMA EVDO on SIM:- 1. We have to know the 8 digit HDR password of the RUIM before begining the process. 2. Download 4620L drivers. 3. Mifi should start installing various ports after installation of the driver 4. Using DFS, connect to status port and send SPC 000000 (the Jetpacks do not listen without this port) 5. Do not read or change any settings 6. Go to data and in HDR UID/Pass write A10000xxx@ in your HDR username, and the RUIM's 8 digit password in the password field. 7. Go to MIP section, without reading write A10000xxx or 'net' in the first profile, same in the RM NAI. 8. Reboot 9. Insert SIM and 3G connected. Requirements and procedure for EVDO on Tata Indicom Photon SIM:- 1. Using DFS, send SPC 000000 and go to MIP profile, enter 'internet' in the first profile and reboot. 2. After this change, any Tata SIM can be used since it has a universal MIP, unlike Reliance. (Any data pack with any denomination works) Note:- This is only for CDMA band of the Mifi. Router configuration is done by wifi by vz.hotspot or . GSM_WCDMA is global auto APN. ZTE 890L is fully unlocked and does not require any tweaking. This tutorial pertains to 4620L, 4620LE and 5510. None tested on MTS. Important update:- For Reliance, universal username/pass = net/net working for evdo on some firmwares and some firmwares need HDR username A1000xxx@hrpd.xxxx in first MIP profile in DFS and nothing else. HDR password is no longer required to work. Mifi4620_Drivers.zip
Guide: Use Beer To Boost Your Wi-Fi Router! How to amplify your router's radio signal by using a parabolic antenna. The main problem with home Wi-Fi setups is the fact that houses have walls. These evil contraptions of brick and mortar attenuate radio signals to a great degree. With enough of them between your router and portable device, the internet connectivity is reduced to crawling about at speeds reminiscent of the student \ shell accounts of yore. Yes, you can always upgrade to powerful 802.11n routers, which are generally outfitted with stronger radios, but where's the fun in that? Especially when you can use beer to boost the signal strength of your g-spec router instead? You heard that right - this DIY (Do-It-Yourself) guide will show you how to increase your router's coverage with nothing but two cans of the manly elixir, and maybe some chakna for good measure. Theory Of Operation The idea is to concentrate the radio waves for a stronger signal by employing a parabolic reflector. This increases Wi-Fi signal gain, thereby increasing its range and giving it enough grunt to pass through walls. It's the same principle used in big-*** military radars watching over the horizon for incoming aircraft and nuclear warheads. To give you an example of how effective this is, here's a graph obtained from a Wi-Fi monitoring utility that shows a healthy 15% increase in signal strength as soon as I deployed the parabolic booster on my router.. What You Need • Two beer cans (soft drink cans will work too, but they don't taste as good). • Heavy-duty scissors. • A box cutter, commonly referred to as just a cutter - the kind you cut paper with. • A roll of cellophane or preferably, double-sided tape. • 6 packaging wires (the wires used to tie up cables in retail packages). Alternatively, use any thin metal wire of similar length. • A sidekick, to help you with the final step. • First-aid kid (just in case). Step 1 Drink beer. Step 2 Cut off the rims at both ends of each can. Ignore the overkill USMC KA-BAR combat knife; you can use something saner, such as a box cutter. Step 3 Use scissors to cut the beer cans along their lengths. Step 4 Cut off thin strips from the ends to get rid of sharp edges. Don't throw the strips away; we'll have use for them later. This is how it should appear at the end. Step 5 Use any reasonably thick rod to flatten the sheets. This is achieved by rolling them against their natural curvature. Step 6 Join the two sheets together with cellophane tape, with the shiny sides facing away from each other. Unless, of course, you've signed a sponsorship deal with Vijay Mallya. This is how the end result should appear. Step 7 Strip the insulating material off the packaging twine to get at the metal wire inside. Step 8 Wind the leftover aluminium strips around a pen to create two rings. Hold them in place with cellophane tape. Step 9 Loop three packaging wires through each ring. Twist them around to lock them in place. Step 10 Use a thumb tack, divider, nail gun, Chuck Norris' eyelash, or any other pointed object to punch six holes through the sheets. Each hole near the corners (marked in black) should be 3 cm away from the short edge and 5 cm away from the long edge of the sheet. Punch two more holes, whose locations have been marked red in the figure. Note that these holes will lie exactly inbetween the corner holes. Step 11 Push each end of the wire through the holes made in the sheet. Step 12 Bend the sheet to form a parabolic shape and twist the wire ends at the back to retain the position, as shown in the second figure. Don't twist and lock the wires running through the middle holes just yet. Step 13 Install the parabolic booster by passing the router antenna through the aluminium rings. Step 14 Download, install, and run any free \ shareware Wi-Fi monitoring tool, such as this one. Step 15 Get a friend \ relative to assist you. While he monitors the signal strength in the utility, you need to adjust the length of the unsecured middle wire on each ring. This has to be done because maximum signal strength is achieved when the Wi-Fi antenna is at the correct distance from the parabolic aluminium sheet. Once your sidekick alerts you about the best signal strength as reported in the utility, twist the loose end of the wires to lock the position. The first image shows how to adjust the position, while the second illustrates how to lock it in place. Note that the parabolic antenna has been dismounted from the router in order to illustrate the above point better. In actual practice, the adjustments and locking should be completed while the parabolic antenna is mounted on the router. Congratulations, you have made your own parabolic Wi-Fi signal booster! Now you can enjoy better signal reception even in the remotest corners of your house. Except if you happen to live in a saas-bahu type haveli.
