Wired client workgroup6/17/2023 Class A addresses should not be needed on the DIR router or required by a ISP that I have ever heard of let alone Charter. Depending what the ISP modems is using for DHCP addresses, if the are the same as the DIR router, then the DIR routers default pool should be changed from 192.168.0.1 to 192.168.1.1 or 192.168.2.1 for example on the LAN side of the DIR router as to avoid conflict between the ISP modem and DIR router. However is some cases ISP modems may not be able to be bridged, thus the DIR router and ISP modem are in a double NAT condition and it's possible to use the IP address that's given to the DIR router from the ISP modem and input this into the modems DMZ. Some ISP modems can be bridged and thus shutting off the modems internal router and then it should pass a public IP address (#.#.#.#) to the DIR router. If the ISP modem does have a router built in, some modems already have a Class C or should have a class C address on the LAN side, usually 192.168.1.#. Unless you have specific needs on the LAN side, Class C addresses should be used and should work for your needs. 172.# or 192.# IP address is used on the LAN side. Standard networking for DIR series routers in use with ISP modems, non router modems, typically use the public IP address (#.#.#.#) that passes thru the ISP modem and to the WAN side of the DIR router. Who is your ISP? What modem do you have? Did you test clients using DHCP from the router and/or static IP addresses? I tested both ways with the same results. It has all the same features, but now Class A network support is broken (at least on current modems). Now, we want to update support to include the new wireless AC standard, so the DIR-850L looked to be a reasonable choice. They also have all the required virtual server and port redirection features needed by small business. They are very reliable (zero failures in many years). The DIR-655 had sufficient features to easily manage small business networks using Class A networks. Yes, the connections were reset and/or devices restarted to ensure fresh connections were made after any changes. The same results were obtained with and without the modem connected, except that clients that could access the router could also access the Internet. Wireless clients worked fine either way, even if they were the same device (not connected to both ports at the same time). If the subnet mask was changed to 255.0.0.0, the wired clients would still get similar IP addresses (10.0.0.x), but they could not connect to the router. For example, if the router was given an IP address of 10.1.1.1 with subnet mask of 255.255.255.0 and DHCP of 10.1.1.20 - 254, wired clients would get a dynamic IP like 10.0.0.200 (yes, 10.0.0.x, not 10.1.1.x) and they could access the router. Yes, the wired client network settings were thoroughly tested. None of the IP addresses offered by the ISP were in the 10.x.x.x scope. Half the networks used static IP addresses and the other half had dynamic. I have no idea why the modem would affect what happens on the local net. So, there was one instance that worked, but the cable company wants to upgrade that modem. On 1 network with an older cable modem and a Class A network, all clients worked ok. On those Class A networks, the router was unable to be accessed by wired clients, but the wireless clients worked fine. 3 of the 4 networks had current cable modems. Link>What Firmware version is currently loaded? 2.03.What Hardware version is your router? B1.Also, I could not find any statement in the documentation that only Class C networks are now supported.įurryNutz, than you for your reply. Support for Class A networks has always been a distinguishing feature of D-Link routers when compared to similarly priced routers of other brands. Is this a firmware bug in the current generation routers like the DIR-850L? Or is this a purposeful new direction for the D-Link router product line? In contrast, previous generations of D-Link routers (eg, DIR-655) work fine when configured as a Class A network. Wired clients cannot browse to the router and cannot access the Internet. However, when setting up this router in a Class A network, wireless clients work fine, but wired clients do not. The DHCP server also allows setting a range in a Class A network (eg, 10.1.1.100 - 200). In the Network configuration, there is no restriction on setting the router's IP address to a value in a Class A network (eg, 10.1.1.1) and the subnet mask can be set to values such as 255.0.0.0 or 255.255.0.0.
