Question about D-Link AirPlus DI-614+ Wireless Router

1 Answer

No access to port 25 for wireless clients

I have four computers (3 wireless, 1 direct) connected to my D-LINK 614+ router. MY ISP is Optimum Online. Last week, all three computers linked wirelessly to the router lost the ability to send email via Outlook Express. However, the computer connected directly to an Ethernet port could still do so. Attempts to send an email via the Optonline mail server results in the following message: The connection to the server has failed. Account: 'optimum mail', Server: 'mail.optonline.net', Protocol: SMTP, Port: 25, Secure(SSL): No, Socket Error: 10060, Error Number: 0x800CCC0E This is error occurs on each computer, so I believe the problem must be within the router rather than an individual machine. I should mention that receiving email via port 110 on each machine is working fine. Optonline tech support tried to fix the problem but was unsuccessful. I tried using telnet to directly access the mail server. It worked fine for port 110, but failed every time to address port 25. To confirm this wasn't a problem with the Optonline mail server, I tried another mail server (my work machine)and port 25 would not function on this server either (the same message was generated). However, on my job's mail server I was able to select a different port (587) for SMTP. This immediately allowed me to send email via Outlook Express. Therefore, I concluded that the problem must be the router will not allow access to port 25 for wireless clients. I reset the router to factory defaults, but this didn't work. I re-flashed the router with the latest available firmware. This didn't fix the problem either. I am not using encryption. The only custom settings I'm using is a MAC filter for router access and static DHCP. So the problem remains that a direct-wired client can access port 25, yet wireless clients are blocked. I'll probably have to replace the router, which admittedly is older, but this is a problem I'd love to solve. Any ideas?

    I immediately thought that the ISP was at fault, and tried to work through the problem with them first. I turned off the Firewall (ZoneAlarm) and AV prog (AVG) and this didn't help either.

    The confusing thing is that the three computers always worked until a week ago, when they all stopped accessing port 25 simultaneously. This brings the ISP under immediate suspicion, but they insist that they are not blocking the port, and the computer connected to the Ethernet port kind of supports their claim.

    I thought about trying one of the computers with a built-in NIC on a direct port to see what happens, although I'm pretty sure it will work if I do this. I will try safe-mode networking, but everything seems to point to the router, rather than an individual machine.

    D-link doesn't support this model anymore, so I guess I have to cough up the money to buy a new router, which definitely won't be a D-link.

What happens if you connect one of the wireless machines with an ethernet cable? Any chance you have a Firewall of AV program blocking port 25 on these machines? Have you tried Safe Mode With Networking? I'm sure you realize that is most often caused by the ISP blocking Port 25, but I assume they would have told you so if this was the case.

My linksys w/2phone ports cannot hook up with the ethernet


Most Cable Internet Service Providers (ISPs) use Media Access Control (MAC) Address authentication to establish Internet connection for end-users. MAC address is a unique identifier assigned to the network adapter/s of the computer.
To set up your Linksys router to work with a Cable ISP, you have to enable the MAC Clone feature of the router. MAC Cloning is a procedure which enables a router to copy the MAC address of the computer registered with the ISP.
To set up a Linksys router with Cable connection, you need to perform four steps using the computer that's been registered with the ISP:
i. Verifying Internet Connection
ii. Connecting the Devices Together
iii. Checking the Router's LEDs
iv. Setting Up a Linksys Router for Cable Internet Connection

Verifying Internet Connection
Connect the computer to the Broadband modem using an Ethernet cable without the router installed. If you cannot get online, contact your ISP. If it's online, use the computer to set up the router.
NOTE: Some cable modems use the USB port. If the physical connection is via USB port, you may not be able to go online via Ethernet connection. Contact your ISP to have the Ethernet port of the modem configured.

kb17251-001_en.png NOTE: The image may vary depending on the computer and modem you're using.
Connecting the Devices Together
After confirming the Internet connection through the modem, connect the modem to the Internet port of the router; connect the computer to any of the four Ethernet ports at the back of the router. For instructions, click here.
Checking the Router's LEDs
After connecting the devices together, check the lights on the front panel of the router. Ensure that the Internet light, as well as numbered light corresponding to the Ethernet port where the computer is connected, is lit. For further instructions, click here.
Setting Up a Linksys Router for Cable Internet Connection

Try to change the LAN IP address of your router to 192.168.2.1 by accessing the router's Setup page. You also need to set your Westell modem to "full-bridge mode". You need to ask assistance from your ISP to bridge the modem. After that, set-up the Linksys router to PPPoE then power cycle it.

Accessing ISP email account


There are numerous ports used and methods to send and recieve e-mail my setup uses the pop / smtp method where I believe the default ports are 110 / 25 however my ISP uses two other ports. Routers with port filtering enabled may allow 110 and 25 by default but are unlikely to permit other ports chosen by your or my ISP. The riskier change is to disable all port filtering. The safer option would be to open the ports required by your ISP (as well as closing the default ports that are unused).

In order to achieve this we will need to determine the ports you utilize for e-mail.

We will need to be able to access the router for configuration with a web browser.

A second option is that your computer has a firewall blocking your e-mail ports. However if this were true your e-mail would never work. The process is similar to the router in that the required ports would need to be open or the e-mail program given permission to access the internet in your computer's firewall program.

This could be a lengthy process determining your e-mail client accessing the configuration to determine the ports used. Determining if the router and/or the internal firewall are the issue and making the appropriate changes to one or both as determined necessary. If you, your neighbor or a friend is knowledgeable in these areas it may be easier to have them as
