Terrible! Couldn't even get past configuration without freezing

Lorelyn M., Newegg
24 July 2014
  • Summary: This could just be a fluke, but it doesn't leave a good impression of ZyXEL. I've been configuring networking equipment going on a decade, and have never had such prominent issues out-of-the-box.
  • Pros: Aesthetically pleasing, bright port LEDs, fanless/quiet, seemingly feature-packed, seemingly robust web-based configuration.
  • Cons: Both of the units I ordered (one of them as a replacement) suffered from freezing issues.

Good Purchase

Jeb H., Newegg
25 September 2013
  • Summary: The layout takes a while to get acquainted with, but that is to be expected. All I have ever used is one competing brand.
  • Pros: This is a feature rich firewall. I was pleasantly surprised. After reading the other comments posted, I updated the firmware first. Setup was fairly painless, help buttons were available in areas where I had questions. I did print a manual to read. I still plan to read it in my spare time.
  • Cons: It was inconvenient to find out the hard way that the DNS defaults to the unit. I should have read the screen more closely. When I typed in the DNS ip addresses it was really for the second and third entries and not the first and second.

Love these things!

Anonymous, Newegg
31 July 2013
  • Summary: We've been looking for a new hardware firewall/router solution for our healthcare clients and I think I've found what I've been looking for. Just have a few in place, but after the second one decided to replace the firewall in our office. Out of the box access is very simple to figure out (uses the default we're all used to). Prompts you to configure a new admin password immediately (no brainer there - hint, hint, D-Link and Netgear).
  • Pros: Inexpensive. Dual-WAN - both Gigabit. Easily configurable LAN ports. Simple DMZ setup. Highly configurable (even use a company logo on the splash screen). Actual hardware firewall and not a 'firewall.' And NOT a Cisco. Praise!
  • Cons: None so far

Great line of routers

Marty W., Newegg
27 June 2013
  • Summary: If your looking for a high throughput, dual WAN, multiple vpn router, this is a great option.
  • Pros: We use this to connect clients to cloud systems, multiple vpn's no problem, web services, monitoring, support. We currently run ZyXEL 100/200 routers, multiple 20/20W's in the field, managed switches in the datacenter. Firmware has addressed every issue we have ever had and their support was great the 2x I've had to call them in over 3 years.
  • Cons: it doesn't make coffee

Good router

John L., Newegg
11 June 2013
  • Summary: Overall very satisfied. The Tech support was readily available when the documentation fell short (which it does quite a bit) and was very helpful. All my issues were resolved within 5 minutes. (Of course I had spent a lot of time testing before the call so didn't have to do much work) If I needed the add on stuff I would have to jump up three levels to get the full 100 meg throughput I needed. That's too bad.
  • Pros: Lots of features, very fast routing and IPsec tunnels. Descent web interface and documentation. Good tech support.
  • Cons: II turned on their anti-virus and Intrusion dectection signature features and the performance tanked. Since I was buying this as a router I didn't care that much but the Intrusion detection signature service would have been nice. I can't imagine the speed loos if you ran the anti spam and filterng apps too. Got my full 100 meg internet throughput with ste apps turned off, dropped to about 35 Meg with them turned on. Documatation is good in ways but assumes you already...

Product good but!

William Y., Newegg
8 May 2013
  • Pros: Product is easy to setup and works well.
  • Cons: The advertising on this product is very misleading. 50 VPN connections and 25 SSL VPN connections. I wanted to use the SSL VPN but soon found out the device is only licensed for 2 SSL VPN users. You must purchase severalty a 5 or 25 user license for more remote connections. Not really happy about this.

  • Summary: you wont be sorry
  • Pros: Very fast, For a small office I cant imagine needed anything more. Above average contruction.
  • Cons: If there is any con it is that since thins does so much it is a little complicated to set up the first time, if you can do a sonic wall this is very close to that

The best I have experienced yet!

Mr. S., Newegg
8 December 2012
  • Summary: I'm not a networking expert; I have no certifications or formal education in networking, although I built and administer our network for the company I work for which has about 75 users and a total of around 125 devices on the network at the main office, and literally dozens of other tiny networks across the country.
  • Pros: Feature Rich. Reliable. Wonderful web interface. Daily logs include statistics, which has been a help for me.
  • Cons: Object oriented programming a little confusing at first; multiple steps required for setting up port forwardings for example. Long boot time (about 3 minutes if I remember correctly).

  • Summary: Throughput with IDP on is reduced by quite a bit.
  • Pros: Feature-rich router that can be had for less than comparable other routers. Free firmware upgrades for the life of the product.
  • Cons: Cost of extra VPN, SSL, and similar options can be a bit high depending on requirements but still not bad.

Have many Zyxel's in the field working great!

Danny C., Newegg
2 March 2012
  • Summary: I have literally every client of mine with hundreds of millions of dollars of companies that depend on these units. Not a single failure or outage due to the Zyxel equipment. Many other brands charge annual maintenance for support and updates, but they provide them for free for the life of the product.
  • Pros: I have at least 8 of the USG 100s and 200s in the field running for SMB customers and have about 50 total Zyxel devices running personally and at multiple clients. Not 1 has every failed! Support is great (real person on the phone in typically less than 5 minutes), and free firmware and tech support for the life of the product.
  • Cons: A few issues here and there that are always fixed by firmware updates. There are so many options that many people get over whelmed but take it slow and you will figure it out. Most people have not heard of the brand.
