Solution 3 – Reset your modem (and more) Now, let’s switch to more basic solutions, which are probably the first thing you’ll do anyway.Here are some of the actions you need to do to troubleshoot your modem/router: Once again, if you’re not sure how to do any of this, check your router/modem manual for more detailed instructions.So if you have DHCP at both ends and you are trying to establish a service that requires IP addressing, you can use this script to make it all work.If you feel so inclined, please leave me some feedback if you found this useful.And here’s how to do that: Solution 7 – Change the number of DHCP users And finally, the last solution that involves the DHCP process is changing the number of DHCP users.More precisely, you’ll have to increase the number of DHCP users in your router settings.hostname=$matichost&myip=$current IP&wildcard=NOCHG&mx=NOCHG&backmx=NOCHG" :if ($current IP ! = $previous IP) do= else=# DNSo Matic automatic DNS updates # User account info of DNSo Matic :global maticuser "user" :global maticpass "password" :global matichost "Yourhost" # No more changes need :global previous IP # Print values for debug :log info "DNSo Matic: Updating dynamic IP on DNS for host $matichost" :log info "DNSo Matic: User $maticuser y Pass $maticpass" :log info "DNSo Matic: Last IP $previous IP" # get the current IP address from the internet (in case of double-nat) /tool fetch mode=http address="checkip.dyndns.org" src-path="/" dst-path="/dyndns.checkip.html" :local result [/file get dyndns.contents] # parse the current IP result :local result Len [:len $result] :local start Loc [:find $result ": " -1] :set start Loc ($start Loc 2) :local end Loc [:find $result "" -1] :global current IP [:pick $result $start Loc $end Loc] :log info "DNSo Matic: IP actual $current IP" # Touching the string passed to fetch command on "src-path" option :local str "/nic/update?

It is NOT impossible, thanks to some scripting and a couple of free services.

Usually, the limit is Once again, since the process of changing the number of DHCP users varies from router to router, it’s better to check the manual for detailed instructions.

Solution 8 – Update network drivers Another common solution for various network issues is to simply update your Wi Fi driver.

So, we need a method to update our DNS entry…a SCRIPT!

Here are some of the most common issues: Solution 1 – Reset TCP/IP The first thing we’re going to try is resetting the TCP/IP stack.
