I r4ealize you probably never visit this video anymore but I recently purchased 2 TP-Link WR940N routers and they are really bad. It doesn't take much to get them to lock up and need a reboot. It gets worse the more bandwidth I am pushing through the Wii router. I believe it's a memory problem so I'm going to try upgrading the memory on one of them and see if it works or helps. I'm an electronics hobbyist with reasonable SMD soldering skills. Nice video. Very useful for me.
Wow! I've added tiny 0402 resistors to get my serial port working but upgrading the RAM is SMD insanity! Good work! My old routers hardly have enough RAM for newer versions of OpenWRT, so it seems like a good idea but.... this is SMD insanity.
do note that knowing what pin layout said chips have is very important... don't want to place a 5v onto a 3.3v or worse short circuit to gnd on accident. Hope you have a great day & Safe Travels!
Hi, I bought a new router for home, by is an old model with 64Mb of RAM. Do you think is enough for home user with IPTV, netflix, 20 IOT devices (Sonoff) ?
please sir any help from you will be appreciated, i need to upgrade my tl-mr3420 v2 to 64M and 16M flash please and please help me with the firmware or resources needed sir thanks.
Frankly speaking, I wasn't 100 percent sure whether it is going to work with OpenWRT, but it worked. I guess it will work with DD-WRT as well, just because I don't see any reason why wouldn't it. But it is just my thoughts.
on OpenWrt webpage they have a list of supported routers with flash and RAM memory details openwrt.org/toh/start but these are only routers which OpenWrt supports, your router might not be in here
isn't there some sort of issue with lead free solder anyhow? I read something about tin whiskers from such solder. Although I have not had any electronic devices fail I most likely have something with that lead free solder in it somewhere. It seems that when something is working right there is always some no good son of a bitch looking for a way to ruin it.
I also heard about tin whiskers, but I've never seen it or experienced any issues related to it. The only issue for me with lead-free solder is higher melting temperature, so sometimes it is difficult to unsolder components. Also, there are a lot of different kinds of lead-free solders, with different additives, so they have very different properties and different melting temperatures. But I am not an expert on the subject.

Hey
Wanna give us an update on your project?
It would be great 👍
I like it. As hobbyist I can appreciate your soldering.

Thanks for these router-reated videos!
I'm going to upgrade my router soon, but just the flash chip☺

Hope you have a great day & Safe Travels!
Amazing work!
Does somebody have schematics TL-WR740n v3? i can't solder the FLASH chip because i screw up the pcb

It is
Great job
Can i swap others models bios chip on tplink router??
Hi bro, what about adding usb port to router 701nd v2 ? If you know pls show how to drill the chip 9331 correctly.
can we increase ram to 128mb or higher ???
please make rom upgrade as well
Good video
How to upgrade phone ram
hello, do you know how to testing ic ram on board ddr3?
Can I do that same with my TP-Link with DD-WRT?
please sir any help from you will be appreciated, i need to upgrade my tl-mr3420 v2 to 64M and 16M flash please and please help me with the firmware or resources needed sir thanks.
Will this work on all router
Where your video to upgrade from 4 to 16 flash
I already use DD-WRT. Do I have to do anything extra or charge to Open-WRT?
Frankly speaking, I wasn't 100 percent sure whether it is going to work with OpenWRT, but it worked. I guess it will work with DD-WRT as well, just because I don't see any reason why wouldn't it. But it is just my thoughts.
How can I see RAM available and used?
how check infomation CPU, RAM of Router any? please help me
on OpenWrt webpage they have a list of supported routers with flash and RAM memory details
openwrt.org/toh/start
but these are only routers which OpenWrt supports, your router might not be in here
Can you do the same thing with a pc
Yes, but no soldering is needed
