D-Link AC750 DSL-2875AL

I've never had a problem – I'm somewhat surprised at all the negative reviews this has received. We bought ours about 4 years ago and from the start it was easy to set up (the only time I haven't had to ring Telstra for assistance) and the speed is better than some of our previous modems and as I said it's been running smoothly for around 4 years. After reading these… Read more

reviews I feel as though I was one of the lucky ones to get a good modem. I know this review isn't going to convince people to buy this model, and I probably won't either once I need a replacement unless I can get one exactly the same as the one I have now.

The only complaint I have is that the reset button doesn't work.

90% drop outs; causing countless missed deadlines and lost job applications – We had Netgear on ADSL. Connections were stable and speed was great even though we were only on ADSL (ADSL2 not available in our area). When we were forced onto NBN we had to buy a "fibre to node VDSL". Not being aware of this requirement and needing connection that night; we ran at 4pm to JBHifi to purchase a modem with no time to carry out… Read more

research.

Simply put: within a couple of weeks i called iinet and demanded they put us back onto ADSL for the new NBN connection spent 80% of its time connected but not actually connecting. I was advised that there were no problems with either iiNet or NBN and that i could not revert.

For months i dealt with a modem that, as i said, spent 80% of its time going nowhere. I missed two job applications because of the constant instability. I want to make it clear; i did not leave these deadlines until the last minute - there was simply NIGHTS ON END WITH NO CONNECTION...

I started a home business and need something reliable so I have asked my husband to research modems and we did so. We discovered that this is a common problem.

Clearly, what we thought was NBN or iiNet problems was simply a bad modem problem.

It may work for you and if it does, great, you have saved money. In our respect the additional expense far outweighed the damages resulting from numerous missed deadlines...

Opens up to CSRF dns hi-jack attacks when ADSL line state is reset – While the hardware for modem/router works fine, the config is easy enough to drive, the firmware is terrible and is full of bugs. This modem router suffers from the CSRF attack, even with the current firmware 1.00.05. Whenever the DSL line resets due to line noise, the DSL-2875AL will often drop its access connection rule, enabling WAN access… Read more

to the standard ports, even though the config is disabled. When this happens the router config web page becomes accessible from the WAN side. ie. all the access ports are open. When I go to https://www.grc.com, do a Shields-up test, and select Common Ports ShieldsUP!! Services. It shows all TCP ports 21, 22, 23, 80 and 443 all open, instead of being stealth! And of course, when the webpage is open to WAN CSRF attack the router's DNS server settings can then be hi-jacked and changed to something else that are not my ISP's DNS servers. This happens to me a few times.

I've tried to set up advanced IP filters to close down all these ports but the filters only apply for outbound traffic. I try to point the access ports to non-standard ports in the high 60000 numbers, but nope, router resets them to the standard ports whenever the bug occurs!

D-Link support for this model is non-existent; D-Link just replied with an acknowledgement that they've have received my email and are looking into it and nothing since then. Definitely looks to me like they have abandoned any firmware update on this model.

I've lived with this problem by constantly checking the remote access of the router's config page, and whenever it's enabled, I toggle the router's config, for 3 months waiting for it to be fixed. But no more, recently I bought a Belkin AC1200 modem/router to replace it and it's completely solid, unlike the DSL-2875AL.

I do not recommend the D-Link DSL-2875AL at all to anyone, especially as the CSRF security hole will never be closed and if your ADSL line state is unreliable and prone to reset, your modem/router config page will be open to WAN access even though it is prohibitively disabled - and with only one LAN port you can't even use it as a network switch.

Still the same opinion! – Well fellow internet users, I wrote a review on this modem/router just over a year ago, and I still stand by what I said. Let's not forget also, this is nowhere near what you would call expensive and I can't imagine how spending 3 times as much would give me any better results. If you're after a mod/rout that will perform great and you haven't got… Read more

a house full of kids using multiple devices, this will do the job. As I said, it runs(Wi-Fi) my pc, tablet and Xbox360. I can watch YouTube on Xbox and it's just like watching TV(does not stop and start). Download full-length movies, overnight(it's not NBN). If you've got good adsl2+ signal and you're not 50kms from your local exchange, if you're not trying to send your Wi-Fi thru 5 or 6 concrete walls and it's just everyday general use, then I would recommend this product. I have never had a problem, except once when the exchange was knocked out after a severe electrical storm,(nothing to do with the modem). PC tells me I'm getting 95-100% signal all the time, and that's about 20 meters around the corner of a brick wall and thru a doorway. I can't fault this product!

A all-round bad product – Complicated set up, poorly worded instructions. Randomly connected and disconnected things. After 15 hours of trying to make it work, I took it back! I will never buy D-Link again.

Constant Dropouts – I wish I had read these reviews before buying this unit, which was recommended by Harvey Norman. Multiple daily dropouts from the first day. After nagging my ISP about it for weeks, thinking it was their fault, they eventually gave me one of their modems to try. Problem immediately solved, with better WiFi range as well. Very disappointing product.

Do not buy this modem - you will regret it – I bought this model modem about three months ago now. At first it worked quite well but that appears to be because I was only using it connected to my laptop. I started using it for some serious wireless work and connections started dropping out. I discovered that the most recent firmware for the product is like April LAST YEAR. Three weeks… Read more

elapsed and last night the connection just totally flamed out. Hard reset, three reflashes, all the connection options, red light - I've looked at the forums and it appears I'm not Robinson Crusoe. By buy D Link, hello new modem.

Piece of cr@p – Worked okay (only okay not great) for a month or two and now it drops out every minute or so. Its off more than its on. Done all the troubleshooting techniques with no improvements. The store (JB hifi) wont give a refund after 30 days so now i'm going to get sent another one of these from the manufacturer. Very frustrating indeed.

Terribly Unreliable – I need to write this review quickly; I dont know how long this DSL 2874AL will remain connected. My experience of this product is the same as other one or two star reviewers here.

Quite possibly the worst modem ever made – This thing is terrible. It can't stay up for 24 hours without requiring a reset, which may or may not fix things. Devices randomly can't connect either via wifi or ethernet, or can connect to the net but can't connect to the modem page (which is bizarre). Devices randomly can't see other things on the network. Before anyone thinks I've just… Read more

got a lemon, I returned it to DLink and they sent out a new one - which had the same exact problems. Piece of junk.

Terrible as! – Replaced a netcomm wireless n with this AC router and i am so disappointed...... (lost of connection, cannot get ip addresses for some devices, poor range.......) I am bringing it back today.....

Useless – Manual says no wifi password when new, would not connect. Login and password via network hard connect also failed. Tried the hard reset multiple times and still no good. Useless and never worked.

Bad Product – I bought this modem router. This modem can not keep connection. and some my devices can not obtain IP address sometimes. I tried relocate & firmware update. But still same problem. D-Link support said just hardware reset & relocate or disabling auto channel scan and try different channels. It can not solve the problem. I replied E-mail. But they… Read more

did not answer. So I bought an apple Airport Express with modem. It's completely no probelm! I should not buy D-Link never ever!

Terrible product – I recently bought this router to replace an old netcomm router. I have had no end of trouble with this router, and support from dlink is non-existent. This router does not hold a config or connections, its unreliable to the extreme and not meeting my needs at all. I'm very disappointed and really just want to have a reliable internet connection.… Read more

When it works, its very fast Bad firmware release or something because its virtually impossible to maintain reliable connectivity for over a couple of days at a time.
