Archer AX80 Router Does Not Recognize Laptop’s IP Address

Topic

New Reply

I am using an Apple iBook 3 laptop running OS9 as an email server on my LAN. It is connected via an Ethernet cable to the router. It works fine with my TP-Link Archer 8 router.

I recently bought a TP-Link Archer AX80 WiFi 6 router. I changed the router on the LAN to the AX80. It works fine except it doesn’t recognize the email server. When I ping the email server’s IP from a PC, I get a Destination Host Unreachable response.

I have been trying to get the email server’s IP addressed recognized for 3 days. I have restarted the iBook multiple times and changed its IP address, but it is not recognized. Since I need email, I replace the Archer AX80 with the Archer 8 at the end of the day. This works and I have access to email.

Any suggestion as to how I can get the AX80 router to recognize the email server’s IP address would be greatly appreciated.

Hope this isn’t too basic. This is how I set up my network.

For TCP/IP My suggestion is to use a static IP address for the server so that the IP doesn’t change. You will need IP address, subnet mask, and Gateway according to your router. If you are connecting with ethernet you shouldn’t need the router ID/pwd.
Example on computer:
IP section
192.168.1.100 (assigned static IP)
255.255.255.0 (subnet mask)
192.169.1.1 (Gateway – usually router IP address)
IPv4 (assuming the older h/w does not do IPv6)
DNS section
192.168.1.1 (I use my router IP, you may use another DNS server)
WINS
NetBIOS name (the computer’s name)
Workgroup (same as other computers – default is often WORKGROUP)

On the Router:
Use the computer name to reserve the IP address (static) in the correct Network bandwidth.

Oh, and be sure ypu have a goor ethernet cable!

Thanks PKCano for your suggestions. I do use a static address for the email server. I have the IP address, subnet mask and DNS information entered in the email server’s configuration. It has been working since 2007, even as I have upgraded the router multiple times over that time span. Also, it continues to work when I revert to the old router. This at least tells the Ethernet cable is good.

IP section
10.1.1.248 (assigned static IP)
255.255.0.0 (subnet mask)
10.1.1.240 (Gateway – usually router IP address)

DNS 1: 68.105.28.16
DNS 2: 68.105.29.16

IPv4

I don’t see anywhere in the old or new router configuration settings to enter a static address for the email server.

Thanks again for your responsiveness and suggestions.

I have an Archer 90. Settings:

Login -> Advanced tab -> Security -> Access Control

You will need:
Device name
IP Address
MAC Address
Configuration type (Wired/Wireless)

The AX80 has two major options when you turn on Access Control. They are Blacklist and Whitelist.

It appears that I would have to add all of the devices on my LAN to the whitelist. I have a few devices that connect via cable to the router and many more that are wireless. If they are active when I prepare to set up the whitelist, I can capture their MAC and IP addresses. However, many get their IP addresses from the DCHP server so that the IP address may change if the lease has expired. Then, the MAC and IP address for such a device will not match with the Access List entries.

Another problem is when we have guests and they want to access WiFi. Will I be forced to setup a Guest Network?

I am just thinking out loud here. Do you have experience using the Access Control setting on your Archer 90?

I would try some experiments on my AX80, but I am also having trouble getting it to access the Internet. It worked the first time I hooked it up, but couldn’t see the email server. The next day I was able to get it to connect following some advice from TP-Link. When I hooked it up today, it did not access the Internet and the procedure I used yesterday did not work. So, I hooked the Archer 8 back up and am quitting for the day. I will work on it again tomorrow.

I appreciate your help and suggestions. I will let you know when I solve my 2 problems.

The router’s IP is not 10.1.1.1 or the top of the stack (used for the Gateway)??
Have you tried using the router’s IP for the DNS instead of your ISP’s??

I use the method I described to attach my two printers and two NAS drives. You don’t assign the devices static IP’s that are on WiFi receiving their IP from DHCp. And I don’t set a static IP for my computers (combination of Macs and Windows) either, for WiFi or ethernet. Only the devices that need to be “always found in the same place.”

My router has been set up for years with the router IP at the bottom of the IP stack (some use the top instead) with the DHCP range at the first 100 addresses above that. The static addresses are set above(/below) the DHCP range, so they don’t conflict with the arbitrary addresses. For example: router at xxx.xxx.xxx.1, DHCP range set at xxx.xxx.xxx.2-100 or 150 (depending how much you need, includes guest that come and go), and printers, NAS at xxx.xxx.xxx.200 to 249 (static).

I use the router’s xxx.xxx.xxx.1 for the Gateway and DNS on the LAN side. I let the router’s connection to the ISP handle handle the ISP’s DNS servers on the WAN side (ie, Cox’s DNS servers 68…. or Cloudflare, or another). I don’t have a server, so I don’t know if it needs to see the ISP’s DNS.

My Mac’s run Windows in Parallels VM’s, which adds another twist because they set up a shared IP internally. But I haven’t had any network setup problems in so long I can’t remember.

Hope this helps.

I think that your new AX80 6E wi-fi doesn’t backward support your iBook’s old 802.11b wi-fi.

I totally missed that point. You’re probably right. It’s been a long time since the iBook 3.
Is there a network adapter with iBook 3 port to RJ45 (with drivers for the old OS) that could provide a later version of 802.11?
He is using Ethernet, not WiFi.

Thanks Alex5723. The iBook is connected to the router via a cable. I didn’t know it had a WiFi capability. When I bought it around 2005, our LAN was all cable based.

802.11b made its debut in 1999, 25 years ago. Time to move on to newer wifi wherever possible.

Thanks Ben. The iBook is connected to the router via a cable. I didn’t know it had a WiFi capability. When I bought it around 2005, our LAN was all cable based.

The wireless components of my LAN use newer WiFi protocols.

PKCano: Problem solved. Access Control was not the solution. It turned out that the Ethernet port I used on the new router was bad. I plugged the email server into a different port and it works fine.

I also had a problem getting access to the Internet with the new router. I finally talked with tech support today. I had used all of the suggestions they had online, but they did not work. What did work was:

• Leave the router on
• Remove the power on the modem
• Disconnect the coaxial cable
• Power up the modem
• Wait 3 minutes
• Connect the coaxial cable

Thanks for your help!

Also, thanks to Alex 5723 and Ben Meyers!
