Udskift din TDC Homebox med et modem.

This Article is in danish as it primary readers should be danish :).

Jeg har i flere år brugt mit eget modem på min TDC ADSL2+ forbindelse (20/2Mbit), i forbindelse med omlægning til en 40/10Mbit forbindelse, blev jeg konverteret til en VDSL2 forbindelse, mit god gamle netgear DM111 ADSL2+ modem, skulle derfor udskiftes til noget som kan forstå VDSL2.

Jeg havde ved et held fået et TDC VDSL2 modem (Askey RTV1800-D79), dette modem understøtter iht. til TDC’s lister både Vectoring, SRA, samt G.INP, hvilket burde sikre driften i langtid.

OBS: jeg har godt nok telefon på mit abb. men jeg bruger det ikke, så disse noter drejer kun om at få internet igennem.

i min naivitet troede jeg at der ikke var forskel på en modem løsning og en router løsning (Homebox), dette viste sig dog at der var stor forskel.

følgende er de settings jeg er bekendt med:

Homebox:
VLAN ID = 101
QOS = 1
VLAN MUX
PTM IPoE

Modem:
VLAN ID = 50
QOS = 0
VLAN MUX
PTM IPoE

Modem settings er fisket ud ved at tilgå http://192.168.1.1 på modemet, Homebox settings er fundet å TDC’s forum.

man kan via modemet hive settings ud, men umiddelbart ikke ændre noget på denne, dette kan man dog workaround ved at redigere den fil man får ud af settings, jeg ligger hermed min orginale fil op samt den redigeret fil som fik min forbindelse til at virke.

 

Original settings fra modem: orginal_setings

De settings jeg kører med idag: working_final_160203

NB: filerne skal ændres så de hedder .conf for at modemet gider at æde dem.

God fornøjelse med at få det til at spille med netop dit modem/router :)

den primære ændring er:

Orginal:

<WANIPConnection instance=”1″>
<Enable>TRUE</Enable>
<ConnectionType>IP_Bridged</ConnectionType>
<Name>br_0_1_1</Name>
<ExternalIPAddress notification=”2″>0.0.0.0</ExternalIPAddress>
<X_BROADCOM_COM_IfName>ptm0.1</X_BROADCOM_COM_IfName>
<X_BROADCOM_COM_ConnectionId>1</X_BROADCOM_COM_ConnectionId>
<PortMappingNumberOfEntries>0</PortMappingNumberOfEntries>
</WANIPConnection>

Modificeret version:

<WANIPConnection instance=”1″>
<Enable>TRUE</Enable>
<ConnectionType>IP_Bridged</ConnectionType>
<Name>br_0_1_1</Name>
<ExternalIPAddress notification=”2″>0.0.0.0</ExternalIPAddress>
<X_BROADCOM_COM_IfName>ptm0.1</X_BROADCOM_COM_IfName>
<X_BROADCOM_COM_ConnectionId>1</X_BROADCOM_COM_ConnectionId>
<X_BROADCOM_COM_VlanMux8021p>1</X_BROADCOM_COM_VlanMux8021p>
<X_BROADCOM_COM_VlanMuxID>101</X_BROADCOM_COM_VlanMuxID>
<PortMappingNumberOfEntries>0</PortMappingNumberOfEntries>
</WANIPConnection>

Jeg vil sandsynligvis skrive mere her ved lejlighed, når jeg får mere tid til at kigge på settings.

How to fix/hack the Samsung CLX-3175FW, imaging unit

Well the place where i do some voluntary work, had this Samsung CLX-3175FW Color Laser printer for some years now and the unit i starting to show to following warning: “replace imaging unit soon” from the old days doing repairs on different printers at the university, i found that a lot of manufacturers place small fuses, software counters that are supposed to make the user replace different parts in the printers normally these parts are quite expensive, some of these “errors” can sometimes be reset without that much work, and the this was one of them.

What you needs is the following:

A Solderings iron

A 56Ω 0,25watts resistor

Let’s get to work.First thing is to take all the color cartridges out of the printer and place them somewhere safe (be sure not to drop the color powder on anything)

next thing is to remove the wast toner box in the left side, now remove the imaging unit.

image_unit_samsung

you should se 2 cobber contacts in the right side of the imaging unit, this small device can be removed from the unit.

resisitor_samsung

inside the unit that i took apart, there where 2 resistors, the small one, is actual just a  “sense” function that makes the printer aware if the unit is not installed, in my case the resisitor was a 140KΩ, the larger resistor was a 56Ω but this resistor was burned and did no longer function. So this resistor functions as a “new” device put into the printer, the printer then burns this resistor to reset the imaging unit counter.

a quick trip to the storage with a new 56Ω resistor, i removed the old one and soldered the new inside the unit, i used a 1% resistor as this was the only type that i had.

i then put the unit back into the imaging unit, and cleaned the unit for any excess toner, and dust.

then i put everything back into the printer and powered the unit on.

i printed a report for the unit and wolia :) the printer now thinks the imaging unit is new.

report_samsung

i den took the unit apart again and checked the resistor, somehow the printer didn’t burn i properly so i remove the resistor , just to be sure that i didn’t break anything, maybe the original samsung placed resistor is easer to burn?, but hey what the heck it did the job.

This fix/hack cost around 0.50DKR, and a new imaging unit cost around 900-1100DKR so witch one do you chose?.
