I got this ASUS RT-AX56U two years ago while my old TP-Link keep rebooting randomly. I got this router at a 30% discounted price during a online marketplace sale. I’m quite happy with the price i get. Three days after that i got the parcel and start to setup the new router.  The setup process for this new ASUS RT-AX56U is simple and everything was done within 15min.

Daily Usage

In term of usage, we work from home since covid. So here are the things that we do daily: web browsing, instant messaging, teleconferencing, mobile gaming, video streaming, VPN, SSH and FTP.  Total device ranging from 8 to 15.

Browsing

i got a very smooth browsing experience. The respond time (If you notice, every time you click on a new link, there is a “Waiting for www.asus.com ….” ) is way shorter than my previous old router.

AiProtection

Few days later, my wife receive a share link from one of her friend. When my wife click on the link, it shows the site is being blocked due to malicious site detected. This is a great feature for non-tech savvy user.

WiFi Coverage

This router come with 2.4 GHz and 5 GHz. Because my head is quite sensitive towards 5 GHz raiod, i disable the 5GHz since day one. I only turn on 2.4 GHz  WiFi at home and the coverage is superb! It manage to fully covered a 1,200 sqft apartment. So far, i didn’t find any blind spot in my house although i just put my router on the floor. (I know i might get a better performance if i put my router on a higher position)

AiMesh

Although this router come with AiMesh, my house is not big enough to play with the AiMesh. Let me check with my neighbours if anyone want to test AiMesh together in the future.

I’m very satisfied with the overall performance, and the router is still in good condition. I would say it can still last for another 5 years and it still can fulfil my networking needs.

If you using network folder or printer, your might encounter some scenario that you might want to logout from the current connected network and reconnect again. This might due to change of user privileges from the connected server, reconnect to the same network folder using different user or etc. I just encounter the change of user privileges from server and it get me more than an hour to figure our how to logout from network share. To benefit everyone, i’ve document down the solution here.

For those who want to logout from network share follow the steps below:-

1. Right click on Window button and select PowerShell (Admin)
2. type ‘net use’ and enter, it will list out all the network path that you are currently connected
3. determine the path (eg: \\somenetworkpath/folder ) that you want to logout
4. now type ‘net use \\somenetworkpath\folder /DELETE’ and enter
5. System should now log you out from the network.

If you are using Custom Taxonomy and writing your own query, try not to use your own variable to declare the posts_per_page. If you use your own variable and it might have conflict with WordPress default post_per_page option and show 404 page not found error. To solve this, just replace your post_per_page variable to WordPress default post_per_page option and the issue will be solved.

$my_posts_per_page = get_option( 'posts_per_page' );

Now, some of you might want to ask, how am i going to modify the default value ?

Just go to “Settings” => “Reading” => and edit the value for “Blog pages show at most”.

Happy coding!

All order has a status. Each order statuses explain where is the order is at the moment, starting from pending and ending with complete. Here’s the order status that are being used in woocommerce:

• Pending payment – Order received (unpaid)
• Failed – Payment failed or was declined (unpaid). Note that this status may not show immediately and instead show as pending until verified (i.e., PayPal)
• Processing – Payment received and stock has been reduced- the order is awaiting fulfillment.
• Completed – Order fulfilled and complete – requires no further action
• On-Hold – Awaiting payment – stock is reduced, but you need to confirm payment
• Cancelled – Cancelled by an admin or the customer – no further action required
• Refunded – Refunded by an admin – no further action required

Hope this helps everyone understand the woocommerce order status clearly!

To apply coupon for new customer in Woocommerce, follow the steps below:-

• Before apply the code below, you have to create a new COUPON. I’ve created a new coupon name ‘firstlove’
• Now you can copy and paste the code below into your theme functions.php

  /**
   * Frontend validate new customer only coupon code
   * hook: woocommerce_after_checkout_validation
   */
  add_action('woocommerce_after_checkout_validation','check_new_customer_coupon', 0);
  
  function check_new_customer_coupon(){
  	global $woocommerce;
  	// you might change the firstlove to your coupon
  	$new_cust_coupon_code = 'firstlove';
  	
  	$has_apply_coupon = false;
  
  	foreach ( WC()->cart->get_coupons() as $code => $coupon ) {
  		if($code == $new_cust_coupon_code) {
  			$has_apply_coupon = true;
  		}
  	}
  
  	if($has_apply_coupon) {
  			
  		if(is_user_logged_in()) {
  			$user_id = get_current_user_id();
  
  			// retrieve all orders
  			$customer_orders = get_posts( array(
  					'meta_key'    => '_customer_user',
  					'meta_value'  => $user_id,
  					'post_type'   => 'shop_order',
  					'numberposts'=> -1
  			) );
  
  			if(count($customer_orders) > 0) {
  				$has_ordered = false;
  					
  				$statuses = array('wc-failed', 'wc-cancelled', 'wc-refunded');
  					
  				// loop thru orders, if the order is not falled into failed, cancelled or refund then it consider valid
  				foreach($customer_orders as $tmp_order) {
  
  					$order = wc_get_order($tmp_order->ID);
  					if(!in_array($order->get_status(), $statuses)) {
  						$has_ordered = true;
  					}
  				}
  					
  				// if this customer already ordered, we remove the coupon
  				if($has_ordered == true) {
  					WC()->cart->remove_coupon( $new_cust_coupon_code );
  					wc_add_notice( sprintf( "Coupon code: %s is only applicable for new customer." , $new_cust_coupon_code), 'error' );
  					return false;
  				}
  			} else {
  				// customer has no order, so valid to use this coupon
  				return true;
  			}
  
  		} else {
  			// new user is valid
  			return true;
  		}
  	}
  
  }

• once done, you can try to apply the coupon code for a new customer. It should work as expected.

If the code above could not satisfied your requirement, you can freely modify.

Happy Coding!
