Hi.

I am thinking of buying the following modem :-

D_LINK DSL-2500U

My ISP is MWEB.Will the above modem work fine?

If anyone is using this modem,please let me know if u recommend it.

Thanks.:)
 
I bought one two years ago, still going strong and they cost around R280 so not too expensive either. It did have trouble allowing our two pc's to connect through it to Mweb, until I figured out to turn on automatic IP instead of using a custom one such as 192.168.0.xxx Although that could have just been some setting I missed.

Bought a second hand one about a week ago and it's working 100%.

Since it's only got 1 ethernet port if you want to connect more than 1 PC to it simultatneously you'll need an ethernet switch/wireless router though.
 
If you already have a wireless access point or a switch in your home, then that router is more than enough. The reason why you'll need a switch/WiFi AP is simple: the 2500U has only 1 LAN port.

You should be able to get the router brand new for less than R300.

You might have to update the firmware of the router to get some features working like DynDNS (or at least I had to update my router's firmware). Once you have the latest firmware, you've got a reasonably feature packed router:
1) it can dial multiple PPPoE accounts simultaneously
2) you can setup static routes (for splitting traffic: eg. local vs international)
3) dynamic dns (for linking a DNS record to your dynamic IP address)
4) SNMP (for monitoring the router traffic)
 
I have a 2500U as a back up, I found nothing wrong with it other than the lack of extra ports and wireless.

I plugged a linksys WRT54g into mine for the wireless and extra ports.

I then got hold of a newer D-LINK DSL-2640U with wireless on-board, what a piece of crap. Dropping the connection every couple of hours.

I am now a huge fan of NETGEAR it runs a little hot when the wireless is on 24/7 but hasn't dropped the line or fell over since its been installed.

I bought one today and it was easy to set-up for Telkom ADSL service. The fact that it's a very Russian version is a bit annoying. The SA D-Link web site is either faulty or down. Does anyone know where can I get the latest firmware?
 
zs7rsw: any particular reason why you'd want to upgrade the firmware?

You'll have to get the firmware from the Russian FTP site, but you have to make 100% sure that you flash it with the same H/W version.

Hi Pada

No good reason, I guess. It just seems to be a fairly old product and I thought it might be worthwhile updating the firmware, if there is a newer version. But perhaps I should let sleeping dogs lie...

Do not upgrade the firmware.

I did this now using http://ftp.dlink.ru/pub/ADSL/DSL-2500U/Firmware/ and the modem is now highly unstable and the interface is slow. It used to be very stable and controllable. I wanted to see if new firmware made it easier to switch between ISPs (the default gateway selection of the old firmware works OK except that MWEB doesn't allow using their DNS servers from WebAfrica, so in the end it's useless). The new firmware interface looked extremely nice, once you figure out where to switch from Russian to English (top right drop down), and eagerly I started setting up the ADSL. This was easy and seemed to work, except that there is a Save button on almost every page which, once clicked, takes a long time to do something and then another save button appears at the top next to an exclamation mark and a message urging you to save the changed configuration. OK, on to DHCP. These settings simply did not stay set. I could export the config to XML, edit the XML, import that and it worked then, but every minute the interface got slower and slower and I often just power cycled the modem to get control back. (I have checked the hardware version as instructed on the firmware site before flashing new firmware). At one point I had two ISPs set up and noticed I could finally also choose which one to use for DNS, which meant this was better, but trying to do anything at this point caused the modem to apparently reboot without reason. In the end I managed to remove all ISP settings, revert to factory settings and put one ADSL interface up for bridge mode. Now the PPPoE connection is made from the wifi router instead.

Looked very nice though, wish it would have worked better, but I really miss my old firmware now.
 
Aessa:
You probably flashed it with the wrong DSL-2500U firmware then.

There are many different build versions of the DSL-2500U - see http://ftp.dlink.ru/pub/ADSL/
Code: 
[DIR]	DSL-2500U/	        13-Jul-2011 15:53 	- 	 
[DIR]	DSL-2500U_BRU/	        13-Jul-2011 11:02 	- 	 
[DIR]	DSL-2500U_BRU_C/	30-Dec-2008 17:05 	- 	 
[DIR]	DSL-2500U_BRU_D/	21-Nov-2007 13:35 	- 	 
[DIR]	DSL-2500U_BRU_DB/	16-Sep-2008 15:11 	-
 
Did not notice those, but I have h/w ver D4 and from the readmes and other russian html files in the other folders I see only A1 C1 and other version numbers, not D4.

This one is the same as the one I used:
http://ftp.dlink.ru/pub/ADSL/DSL-2500U_BRU_D/Firmware/NRU/1.0.47/
but this one I'm not sure of
http://ftp.dlink.ru/pub/ADSL/DSL-2500U_BRU_D/Firmware/RU_1.58/
except that this readme does not mention D4
http://ftp.dlink.ru/pub/ADSL/DSL-2500U_BRU_D/Firmware/
The changelog there does mention D4, so I might as well try the RU_1.58 later then.

P/N ends with EBRU9D4E so assuming BRU_D is the name to look for, matching the RU_1.58 location. Will try this tonight and post results for completeness.

Thanks.
 
OK that first attempt was with the wrong firmware, just lucky it worked at all I suppose.

First, the details of what worked:
DSL-2500U
P/N: RSL2500UEBRU9D4E
H/W Ver: D4 F/W Ver: RU_1.53
http://ftp.dlink.ru/pub/ADSL/DSL-2500U_BRU_D/Firmware/RU_1.58/

That worked out perfectly. Back to the old interface though, but it seems faster. Don't notice any reason to go for the upgrade and if the change log in http://ftp.dlink.ru/pub/ADSL/DSL-2500U_BRU_D/Firmware/ is worth anything (save html file, open with chrome, translate pop-up makes life easier), the changes weren't many. After the firmware flash the modem was eerily quiet, so I left it 3 minutes and power-cycled it. Came back just fine.

This thread, after translate, helped a bit:
http://forum.oszone.net/thread-135031.html
Also translated the readme next to the changelog and it turns out it very nicely shows you how to make sure which firmware to choose using images. Most importantly from my side, do not just use the first google result...

All in all, these dogs are sleeping again and I'm letting them lie now.
 
Cool, glad to hear you've managed to flash it with the correct firmware version and have everything up and running like it should ;)
 
Sorry to revive an old thread. But I found this thread useful so I thought I'd contribute rather than create a new one.
I've got the identicle device and the up to date firmware (RU_1.58).
My problem is the virtual server setup.

Ok, so I can't find ANYWHERE to change the admin interface from port 80 to port whatever (90).
If I add a virtual server to forward 80 to my internal web server, it informs me that the admin web will change to port 8080. It then succeeds in adding the virtual server, but thats about it. It still stays on port 80 and my forward isn't working.
grrr....
 
Just remember that the admin port is changed to 8080 ONLY on the WAN (PPPoE) connection.

How are you testing your port forwarding? I hope that you're testing it from a different Internet connection, even if you are just dialing another PPPoE connection from your PC.

I can't find a setting on my D-Link (v1.53 firmware) to change the port of any of the services (telnet, http, etc) either. I would actually recommend that you disable the services on the WAN/Internet connection, unless you have a very good reason to log in remotely to the router itself.

Once again .. apologies for reviving such an old thread, but what the heck ... it is useful!

I have the identical hardware (D4) and the identical firmware (RU_1.58), and .. the identical problem!
riverdusty, did you ever get to the bottom of the port forwarding thing ?

If I set a "Forward all ports" rule to forward all ports (1 thru 65535) to a LAN-side address, I also get the message about the admin port being moved from 80 to 8080 (presumably on the WAN side).

But ... after activating that port-forwarding rule, the forwarding doesn't seem to work. And ... lo and behold .. when accessed from the WAN-side on port 80 (HTTP), up comes the modem's login page !

This is especially weird because HTTP login from the WAN side has been expressly disabled :

DSL-2500U service control page.jpg

According to me, the DSL-2500U shouldn't even be responding to HTTP requests on the WAN side, not on port 80 or 8080 !
So what gives ?

Grateful for any support/advice you can offer.

It's ooooold news now, but .... just wanted to say a huge "thank you" for that post, Aessa !
I have the exact same modem (and firmware, now) and your post was a lifesaver for me a while back!

Do you still have your DSL-2500U, or have you changed to something different now ?
