Enjoy ultra-fast WiFi

With the ASUS DSL-AC88U WiFi Modem Router you can experience ultra-fast WiFi speeds of up to 2167 Mbps. Whether you're gaming online or streaming 4K Ultra HD movies, the router provides fast performance at all times, so you can enjoy smooth streaming and low-latency online gaming.

Make the most of multiple ways to connect online

The DSL-AC88U is a two-in-one router with multiple ways to connect to the internet. You can use the DSL-AC88U as a modern router or as a standalone WiFi router according to your needs. It lets you switch between connections if one fails, and back again once it's fixed.

Beamforming technology

A four antenna design provides a wider WiFi range and stronger signal stability. AiRadar beamforming technology focuses your signal directly to your devices – and not around it like some routers – which means you get faster, stronger and clearer WiFi.

Connect to USB-enabled devices

With built-in USB ports you can connect external storage drives, printers or 3G dongles, and share them with other users via WiFi. Share 3G and 4G, files and connected printers across your WiFi connection.

Good performance, typical Asus routing kit
No compatibility with any of the rest of the Asus AIMesh systems so it's an expensive elephant.

At this price, you're better off buying a £30 tp-link router that can go into modem mode and an Asus AX-56U. You'll get the modem speeds, a WiFi6 network that's future-proof and you'll still have change left over for a takeaway.

Good stable modem router that copes well with multiple tv’s streaming, laptops and phones running internet all at the same time
Can be a little tricky to setup and VPN not available straight out of the box as you need additional software to run the VPN

Delivering your online order

Get this delivered when it suits you

We’ll show you your current delivery options for this item in checkout. Subject to the time you order, and where you want delivery, these options will include:

  • FREE standard delivery in 4-5 working days
  • Next day delivery or any following day between 8am & 5pm (£5.00)
  • Delivery in a timeslot of your choice next day or any following day (£10.00)
Please note: if we’re out of stock of an item but getting more in, we indicate – on listings pages and the product page – how soon we can dispatch for delivery to you. In this case, please go ahead and order, and we’ll contact you later to confirm an exact delivery date.

Important update on our delivery service for small items

Our courier partners (DPD, Royal Mail and On the Dot) have all updated their delivery processes to take extra precautions due to Coronavirus (COVID-19). Please follow the below advice:

1. Customers can use the DPD app to nominate a ‘safe place’ for their delivery to be left if they do not want close contact.

For customers unable to use the DPD app, DPD is still able to offer a contact-free delivery, and will take a picture of the property and capture a proof of delivery name instead of capturing a customer signature.

2. Royal Mail is an unsigned service . Where Royal Mail needs to deliver a parcel, its teams will place the parcel at the customer’s door. Having knocked on the door, the delivery teams will step aside to a safe distance while the item is retrieved. If the delivery cannot take place, Royal Mail will take the parcel to the local depot for collection by the customer.  The parcel will be held for 18 days as per normal process.

3. For On the Dot, where a standard signature delivery is not possible, On the Dot will attempt to leave the parcel in a safe place and inform the customer of where the parcel has been placed.

To see the courier partner for your delivery, please check your dispatch confirmation email (which will also include your tracking reference).

Returns and refunds

Whether an item you’ve bought is faulty or damaged, or you’ve changed your mind, it’s easy to get a refund.

Items you haven’t opened
Within 21 days of receiving an item you paid for online, on the phone, or in store you can return it for a full refund – provided your purchase is still in its original and unopened packaging. This promise is in addition to your statutory rights.

Items you’ve opened
Within 14 days of receiving an item you paid for online or on the phone, you can return it, even if you’ve opened it. To receive a refund, you must:

  • Let us know you plan to return the item within 14 days of delivery/collection
  • Physically return it within a further 14 days.
The item must be returned in ‘as new condition’ – not used or installed, and in its original packaging. More on returns and refunds.

Order online and collect in store

Order & Collect ­­– The majority of our stores are now open and offering a collection service, allowing you to safely order online and collect from store contact-free.

Our stores with parking available can offer a Drive Thru collection experience using the parking bays clearly marked outside the store. Here’s how it works;

  • Once you’ve had confirmation your order is ready to collect, drive to the store.
  • When you’ve arrived, click on the link in your confirmation email to let our team know.
  • One of our colleagues will put your order in your car boot.

Stores, including those which DO NOT have parking outside, can still offer a safe Walk Up service. We have safety measures in place to keep you and our staff protected whilst you queue. Here’s how it works;

  • Once you’ve had confirmation your order is ready to collect, walk to store and head to the collection point.
  • When you’ve arrived, click on the link in your confirmation email to let our team know.
  • You’ll get a text when our colleague is preparing your order for collection.
  • Please remember to keep 2 metres away from our colleagues and other customers.

If the store already has stock of your item, you may be able to collect on the same day. If your store doesn’t have stock, we can get some in, but it may take a little longer. Don’t forget to wait for your ready to collect email and check store opening hours and whether the store can offer Drive Thru, Walk Up or both collection options before heading out.

We strongly recommend that you check whether you will be able to carry the item, or whether it will fit in your vehicle before placing your order.
