I made maxim 232 chematic and I try to recover my Tenda w311R+ router, but when I power router in putty I recive this message (only at 57600 baudrate) LOOK AT THE PICTURE.
What can be the problem?
It stop here I try 20-30 times to plug in and out router power supplay but same!
Is that mean that my router is totaly bricked?
If I use default boudrate 9600 i recive in putty unrecognized symbols..just in 57600boudrate speet it show me text (attachment)
I supply my schematic with 5V but try with 3,3V and same situation.
Please help!

Did you configure the port at right speed in putty?
Try with NO FLOW CONTROW, turn off windows firewall and go to device manager and set up com port as setings as putty then try again.
and pay attention to this post: Ok, i did it, build a serial adapter with a MAX232 and two resistors on the tx-output for the W311R (to get 3,3V) It´s working again! Flashed it with DD-WRT, yeah ...
which firmware you flashed and bricked the router ?
which was the original firmware ?

If you need more help just write here
First off all thanks to "TendaW311R+" user to helping me!
Yes the only right speed is 57600 all other speed give me uncecognized caracters on putty serial connection!
Yes, I try to turn off flow control and same try to det settings as in putty in serial port and yes I turned off win firewall and ESET NOD firewall.
This part of text:

is not clear for me!
Which two resistor? Where to put? How many Ohm?
Can you put some picture?
Is it correct to supplay max232 with 5V or with 3.3V?
Why in my putty window write that I have 256KB?
I don't know what happent with router.My friend give me if I know to repair it. He said that he didn't flash with any firmware, but when I power router only power led shining. So there is no system on router, he doesn't booting, but when I connect tenda UPT cable in any yellow port to other swtch/router in switch I see that it led diode comes on!
So..please help me and advice me!

Hm, interesting. Did you test the power adapter ? - use multimeter to test it. It seems for me that there is a problem with some chip or power level or baybe the router is die. Maybe bootloader is dead. In first post of kapastratos the size is different and the start is different
According to resistors: I think that it can work without resistor but the text in terminal will not be readable or hard readable.
Did you read my posts in this topic ?
I had tenda w311r+ and damage pins (tx,rx,gnd).
Please tell me what solder did you use because I want to buy one for me to learn how to solder. I want universal one.

Yes, I'm test with multimeter and try other adapter for Tenda router it is OK.
The power supplay for max232 is PC power supplay and I try with 3.3V and with 5V. There is no diference.
No didn't find you post about rx tx, but I read whole forum, meybe I do not remember. Tell me the page number and I will find.
So what can I do now?
Is this router fully dead? What can I try yet?
About resistors..where can I find post about resistors? Can you post me here link?
About soldering..I'm buy solder in special electronic store..so I don't know the type of solder.

The post about resistors is in first page of this topic. I think that there is dead chip and you can use router only as a switch. Try to connect some port of router to another router and see if the second router 'see' the mac address of Tenda.

Ok..I found the story about resistors.
As I understand he only need it to get 3.3V, but he doesn't describe why he used it, which value he used!
Can anyone tell me something abot this?

Another idea: watch booting from putty and try to connect Tenda to another router/computer and see if there is difference in bootlog
