Bionic TCP Buffer Tweak
Free AppAbout Bionic TCP Buffer Tweak
**REQUIRES ROOT**
Your DROID BIONIC contains a hidden feature where network buffering parameters within its Linux kernel are modified and managed according to the type of network connection you are using. For unknown reasons, Motorola and Verizon have the buffer sizes for their 4G LTE link set comfortably high while all other network links (including WiFi) are set very low.
This app provides a tweak to /proc/sys/net/ipv4/tcp_[r|w]mem and /proc/sys/net/core/[r|w]mem_[default|max] to increase the buffer sizes for WiFi and 3G to those used by the 4G LTE link.
Takes effect immediately, and modifies the properties for 'wifi' and 'default' profiles so they match those of the 'lte' profile. This ensures the new settings take effect seamlessly as you switch between wifi and 3G or 4G LTE.
Provides a "Default TCP Buffers" button to roll back to the Bionic's default settings.
This app does not load these settings upon reboot automatically; you will have to load the app manually after a reboot to force the settings into effect. I will look into automating this later.
I have not run any speed measurements to prove out whether this improves network performance, but with my own usage it does seem that webpages load quicker and don't "hang up" as often during loading. It's a subtle difference. YMMV.

I love this app since Droid 2.3.6! I just wish it would stay on and wouldn't need me to enable it after each reboot. But, not real complaints… superior wifi speeds when it's enabled.

This app absolutely FIXED my connecting issues! I would go from having the Google services that turns your 4G LTE letters blue, and no Google service which turns the letters white. I would go through this continually sitting in my home NOT moving around. I would also lose network connection as well, losing everything... 4G/3G, including all bars. I updated my Bionic when Verizon rolled out the update just a week ago, and ever since then I had TERRIBLE connection. So I perused the internet trying to find a way to uninstall the update but ran into an article praising this app. So I downloaded it and.... BAM... it fixed everything! I'd pay a pretty penny for this app! THANK YOU!

You have to manually reapply every time you reboot phone.

Not sure why a wifi tweak also fixed Bionic's notorious data drops issue but I'm almost certain it did. Could be coincidence. 5 stars if its true. Oh, and Wifi is a little faster too!
