hi everyone.
i got here through google.
ill explain the situation first, en then the f*ckup i made.
i bought a keeplink. managed poe 8 x 2.5 1 x 10
from day 1 the sys light kept blinking.
the switch worked normal.
gui worked. and a switch is normaly a set and forget item.
3 a 4 weeks later my internet connection droped.
reset all. modem, switch pc. still nothing.
tryed gui ( 192.168.0.10 ) no exces. did factory reset of switch and it worked again.
now. 3 weeks later my internet speed dropt from 300mb to 80mb
tested modem ( wifi on phone is direct on modem) and that had 300mb.
problem was in switch. reset. no good.
again factory reset and the speed came back to 300mb.
set ip subnet and gateway again. all good.
but light still blicks. so reading this whole tread #326
i thought that might be the problem.
so i flashed it. now it is bricked.
( i blame only myself ) and in this case the cheap chinees chips...... i think its an hardware issue off faulty chips.
some keeplink guy said he flashed it, and it works, so i dont think its an software issue
its stuck in a boot loop. de s 9 and p lights blink. and the connection lichts light op ones orange. ones green and that just repeats.
no connection through utp.
192.168.1.1 , 192.168.0.1 x.x.1.168 x.x.0.168 x.x.2.1 x.x.2.168 x.x.3.1 x.x.3.168
( and yes everytime is put my pc ip in the same range before i tryed )
connected pc. direct to switch ( everything else disconnected )
i tryed networkscanner nothing found in the network ( normaly i should find the gui login page ) full range 192.168.0.0 to 192.168.255.255
so it is officialy dead, i just went to amazon and orderd a usb serial connector and it should get here this week.
i wil try to document the repair. because its not realy clear on how i should do it. ( putty and and esc and a kabel , no idea )
3.3v and no vcc connected. post #216 is no help for a noob.
reading the rest. i might have an suggestion. take first page. pin first post. and make an overview of all download links PER ROUTER.
make a CLEAR disintion on 4+1 4+2 8+1 poe and managed. and ad keeplink in ( haha )
because reading 25 pages and 494 post. was 6 hours of my life i never get back.
the thread is for 1 router. but some people start talking over other 4 +1 firmware. that will brick a 8+1 mine. and you lose overview,. and gets confusing.
gtz. keep you posted
it took 2 days off figuring every thing out. and a lot, really a LOT off flashing
the short awnser is im f*cked. the switch is bricked. it is a chip problem. i need to order a new one 2 euro for 10 pieces. and find someone to solder them on. ( i dont like micro soldering ) a phone repair on the corner can do that for me,
i do need someone to lift the KEEPLINK firmware v100 from their router. the 8 x 2.5 1 x 10 mananged and poe version. or any 8 poort at this point. ( poe is hardwired doesnt need software to work )
thats how it sits in the corner at the moment.
the long story is
i got an 232 board. connected the rt tx and gnd pins to the pins in the router.
openend putty at com3 57600 baud and plugged in the router
tekst starts scrolling. and its the bootloader. till the line open web dumb. and then it doesnt start the web. but restarts the bootloader. over and over. pressing esc.. ctrl alt esc. and ctrl alt and [ doesnt work. but ctrl alt and [ , and holding it. lets it run till the mac adres line. at that point it stops scolling and the connection light on the switch commes back on . at that point the switch was accecsable at 192.168.1.1 ( my original )
and i can upload new firmware. but after reboot. same boot loop.
a few things i notised.
with serial connected when disconnect the usb line. the board stil has power. ( strange only rx tx and gnd connected )
the light stayed on.
so after flashing. i disconnected the power. the serial connection. and disconnected the internal powersource ( the light was on for 3 min after i pulled the power cord. so i geuss some VERY heavy cappasateurs. normal is like 10 20 sec all power off and dissapated
after the 1.9 still had the bootloop i thought to myself f*ck it. its bricked anyway. so. i downloaded all the bin files from this forum.
and try every single one. also the 4+1. i flashed them all to test, even googled bin files 8 + 1 router and flashed those.
even the l3 routers. also the 12+4 8+4 8+2 so basicly ANY bin file i could find. close enough
strange enough. the didnt even give that mutch errors durring boot.
because unmananged normaly just work, nobody uploads firmware. i would like to test it though. unmanaged is beter then bricked.
my old switch i connected it, and it just worked for 5 years. this managed sh*t, well. i think i know why the good brands cost 500 euro.
if a 5 cent chip crashed the entire switch..... that sucks.
12mb 10 mb and 6mb and all bin files i could find
i didnt get a fault code or errror durring flashing.
some firmware flashed and then the ip jumped. i found 192.168.1.1 192.168.1.168 192.168.1.199 as flash login ( funny is. in putty you can see 192.168.0.10 as login site )
watching the boot in putty. i didnt see very strange errors with the boot. it just kept rebooting after the load web line.
all the other brands. some just booted. with errors but still all gave a boot loop.
the one thing that bugs me is that 1 bin file for a 4 + 1 switch ( this forum ) acually made the S light burn in stead off blink. it look fine. but the bootloop still looped. all the other bin files all kept mij S light blinking.
the S light blinks at same speed as the wrightspeed when flashing. so my logic is that the blink is the acces to flashrom. loop = blink. normal = burn.
after all this my conculsion on my keeplink is : the flash chip is broken. thats the problem. not so mutch the firmware.
i need to order one and resolder it. reflash it. and i think it will work. the poe is hardwired so that always works. so managed firmware is fine.
i installed linux on a old laptop. and wil try to reverse the bin firmware. see if there is someway to get a linux shell in the router going. or something we can change. because there is 0 support from manufactuar. no updates. it is just sell the stuff. and forget the customer.
nothing is documented. the bord isnt online. no specs. you can google the chips. but also not all off them.
but i would need to talk to someone with a bit more knowhow.
