yeah, i think it's about every seven days the connection got dropped. when i called verizon DSL support, they tried hard to persuade me to upgrade to Fios. the woman kept saying Dsl is outdated and bound to have problems. that really annoys me. in the end, nothing was done to fix my problem.
the Aus 3.02 firmware seems working, but upstream speed is very slow, that wrecks my voip service. maybe i didn't get all the settings correct.
I updated my DSL-2750b (hw:T) to AUS3.02 and turned it back into a fine device. I am running on Verizon's DSL network in the USA with no issues at all. Verizon seems fine with it as long as you know what you are doing (ie not peppering the helpdesk with dingbat calls, etc.) (I save those for "FurryNutz! (just joking)), but if you don't know what you are doing it simply won't work and Verizon won't help you to make it work either. Verizon already has their network auto-polluted from themselves, so I consider the way I am running the DSL-2750b T1 to be cleaner than the out of box experience that Verizon provides. And I prefer the D-Link interface over Verizon's any day (Verizon's firmware reminds me of AOL. Every page is plastered with the word VERIZON. It's convoluted, time consuming to navigate and proprietarily cryptic. All in all Verizon firmware is a difficult to tolerate experience and a headache to tweak. Did I say that the USB port won't work with Verizon's firmware (no... I didn't and no, it won't). But I won't be using that feature anyhow as it adds a potential security risk on my front end and a hard disk to boot, mercy sakes alive, you better know how to nail that down if you are going to use D-Link DSL-2750b as the connection to your internet provider and install a USB disk on it as well!
I use the DSL-2750b to make the connection to Verizon and thats it. Under SETUP, Local Network, ROUTER SETTINGS -> I have configured the DSL-2750b with a static IP address (although it's not necessary, the third byte of my 2750's IP address is different than the rest of the local network, it keeps things pleasantly unpredictable in "my little network of treachery" (for hackers, etc) and gives me a noticeable demarcation that I'm at the boundry between my local network and the Internet. The network class remains consistant (ie the subnet remains the same).
There is no wireless, no igmp (any ref to IGMP is disabled), no DHCP, no verizon DNS (use openDNS or some other available DNS for best results), disable packet flow accelerator, no QOS, no Queue config, under advanced> network tools> the only box checked is ADSL2+, no UPNP (security issue), no IPV6, WMM disabled, multicast set to AUTO (even though disabled), OBSS disabled, under multicast---> no boxes checked, no IGMP snoop, no SNMP (another security issue), under TR-069 (potential security issue) Inform Disable, Display unchecked, connection checked, make up user name and pword, WAN loop, acs user/pw same as connection request, interval 300, https://noacs.com .
Under Internet Setup: Its DSL (not eth WAN of course), VPI/VCI 0/35 VLAN MUX n/a, pppoe_0_0_35, PPPoE, Serv cat UBR without PCR, QOS is set to strict (though I don't use it), auth method is auto, check dial on demand (with idle timeout), uncheck pppoe pass-thru, mtu 1400 MRU 1492, no ppp ip ext, ----> NO CONFIG KEEP ALIVE! (if your problem persists perhaps try it (if it is currently checked and you are having issues get rid of it)(the same holds true with that other setting---> IDLE TIMEOUT, I'm using NAT and firewall (contrary to popular belief and advised configuration), NO IGMP (I have IGMP stuff enabled at the router (gateway)), service name pppoe_0_0_35, WAN IP address is dynamic.....
I use a network jack from the DSL-2750b and plug it into the yellow internet jack on a netgear WNR3500 wireless router and I config all the necessary options on the netgear router and keep the intenet modem as simple as possible. (except for firewall and NAT). Basically my gateway IS the netgear router and the DSL-2750b is the intenet.
With verizon speed test I get Latency = 40ms, Download = 14.22 MBps Upload = .94, highest rates at off peak hours. Its never dropped anything. I've booted it 10 million times since last week though (checking features and tweaking, etc, so who knows? I may have a problem and just don't know it. My network is still a work in progress, my ISA firewall is down and under construction, etc. (But, why yes, I do have a honeypot (but its more like a Ya-te-veo))
At any rate I really do like this DSL-2750b now that its de-Verizoned. I'm not very comfortable demoting it as I have in its current configuration, so I may very well change it all around, disable the modem and use it internally. This device has TREMENDOUS potential. But if you want to use it as a modem to Verizon I am pretty much fairly well versed in all the different configurations on how to do that, so feel free to ask me any questions and if you need my email address, just let me know. I could even make a config, back it up and email it to you if you want...
Good Luck! I hope this helps. Let me know if you have any questions, etc...
PS. Never doubt the ability of a defective network cable to mysteriously ruin a perfectly good setup. In this case I don't think it matters if you are using crossover cables or normal network cables--- but it depends what you are connecting it to / to it. AND another thing to check with connection issues is the network interface box. Its the grey box outside, in case you didn't know. Go give it a physical checkover, make sure the screw is tight (not hanging wide open), damaged, etc... if all looks normal, open it and look for mice, ice, water or anything absolutely insane. Even the connectors inside could come loose from wind, rain, sleet, etc and the vibrations that they can produce. You could also get interference along the whole wire (inside and out) (from the Dslam to your PC) from flourescent lights, micorwave ovens, drug stores (satellite broadcasts), there is no limit for the imagination with regards to DSL and line interferance issues. The good news is you only have 2 or 3 miles to investigate if you are desparate and you can't get verizon to do it, but they will blame it on your DLS-2750b and the DLink firmware, because it will be easy and convenient for them to do so. So swap in a different modem if you can and verify that it isn't the DSL-2750b itself and if the problem persists with a different modem don't use the dsl-2750b until the line issue is fixed... I'd try to stay off the radar with it, that is if it is a verizon issued device--- otherwise don't let them put verizon firmware on it or you will hate it and want to throw it in the trash. And you aren't missing any filters on any of your telephone devices are you? (I had to ask)
