D-Link still the best

I owned an old D-Link 614 router for more than 5 years with no issues. Last year I decided it was time to upgrade. I asked for the DIR-655 for Christmas and got it. It's been almost a year now and no issues at all. Very reliable and much better reception than my old 614. I think that this is such a great value that I replaced my family's router for one of these a month ago.

I've had this router about a year.  It's simply the best wireless router I've ever used.  I had to give my vote for it because I see it getting some bad reviews here.

Opening ports is simple and works every time without restarts and such.  Setting up is easy too.  I haven't had to upgrade the firmware.  It's never dropped a connection on me in a year of use.  The internal software is quick too when you open ports or make any other changes.  Wireless and direct connects are fast with no speed loss.  I even have a Vonage phone system connected to it and it works without any break up.  In addition everything is nicely color coded.  The firewall works great.  When I have all the ports closed Zone Alarm never has to block a single external access attempt.  Just a great piece of hardware.

Very pleased with this router, Linksys makes the best routers IMO.  After my headaches with D-link this is a pleasure to use.  My D-Link router used to drop connections all the time,  I got so mad I think I used a hammer on it and went back to my old Linksys. lol  I bought this to replace my old Linksys router.  I also set up a NetGear router for a friend and that was as bad as D-Link or worse.  It kept dropping connections. We returned that one and got the best Linksys router available at Best Buy.  We set it up without any problems or dropped connections.  I never have problems with Linksys.

I have my router set up upstairs with my PC.  When I connect downstairs with my Mac Laptop I get a great signal, 5mb line, 566k per second transfers.  No complaints here.

My set up is a homebuilt AMD 64 system with XP service pack 2, all updates.  I'm using firmware version 1.00.5.

After reading all of the negative reviews about the early firmware I was a bit hesitant to purchase and was looking at the N56U as a cheaper, more battle-tested alternative.  My current D-Link gaming router was nearly $200 back in the day (2007) but has quickly become outdated with modern WiFi standards (mainly security).  I decided to order the N66U and received it very quickly from Amazon.  It shipped with Firmware Version 3.0.0.3.90 which is newer than the version giving people trouble.  I did notice there is now an even newer version than that available but I haven't upgraded yet.

The router is beautiful.  It runs cool, is easy to setup and has exceeded my expectations.  I have 2 HTPC's in the house, one behind a concrete wall.  My old router could barely stream SD movies to it without disruption and drops.  Since I installed the N66U as the backbone of my home network, I have been able to stream 1080p MKV's with DTS through my concrete wall without a single hiccup!  I was floored.  Really surprised me.  It has been up and running for three weeks without rebooting or needing further configuration.

Here's a list of connected devices:
Gaming desktop PC
File server PC
Living room HTPC
Bedroom HTPC
2 LAN printer/scanners
Cisco VOIP office phone
Wii
iPad
2 iPhone's
AppleTV Gen 2
DirecTV whole home DVR's

All devices were easy to setup with WPA2.  I love having the 5GHz band for HTPC's and iPad and the 2.4GHz band for the others.  Also dedicated Guest network that keeps guests off my LAN but provides access to the internet.  So many advanced features as well, too many to describe here.  An excellent value.  Kudos Asus!

I carry this where ever I go with my laptop. It fits in a pocket and gets good range with D-link and other brand APs. I've used it at hotspots with no hang-ups what-so-ever. At home I get my full 22Mbps connection speeds, but out on the road I still get a fast 11Mbps. Software is better than XP's Wireless Configuration thingy and I recommend this over other adapters because of all this.

Been using 24/7 for SDR & they run great. Very happy with this dongle, a lot of fun

My first D-Link wireless router was a DI-624 that I purchased about 10 years ago.  The wireless in the DI-624 started to drop connections, so a year ago I purchased a DIR-880L AC1900 to replace the DI-624's wireless capability.  I moved the DI-624 in between the cable modem and the DIR-880L and disabled the wireless on the DI-624.  This added another layer of protection and let the DI-624 handle all the crap network traffic (such as port scanning).  Well, my faithful DI-624 died.  So, I purchased the DIR-866L to replace it.  Might be overkill, but I love the granularity of the user interface and configuration options.  Very satisfied.

1/2/2016 update:  My DAP-1650 (wireless access point extender) connects to my DIR-880L via 2.5GHz and 5GHz with no issues.  My DIR-880L connects to my DIR-866L via wired Ethernet.  My DIR-866L connects to my cable modem.  No dropped connections or router reboots from any of these three devices.  Been running like a champ for three days, now.

The WRT54G, introduced in 2001, was the original hacker's delight.  Linux-based, plenty of expandability, and best of all, 3rd party firmware.  The GL is the same router as the original WRT54G.  Linksys has since cheapened the WRT54G series, using less RAM, slower procs, and worst of all, VXWorks instead of a real Linux OS.

Over the years I've ran various 3rd party firmware on them.  That's of course why you buy this model!  DD-WRT is for those who want ALL of the features possible.  Maybe it's better now, but it's occasionally sacrificed reliability in the name of advanced features. I personally run PolarCloud's Tomato on all of mine.  Stable, clean interface, and it can handle a decent amount of traffic without bogging down.

Some 12 years later, these routers are starting to show their age.  No 5GHz support, no USB support out-of-the-box (although some people have soldered USB ports onto them), slower procs, only 802.11G and not 802.11N or 802.11AC.  That said, I still have quite a few of them out in the field for both business & home use.  I even bought one this year to replace one which took a nasty lightning strike.

I mostly use these as pure routers and shut off their WiFi APs, preferring to deploy Ubiquiti's UniFi and AirMAX wireless access points which run 802.11G, N, and AC.  No reason to replace the router if it's doing the job and wireless technology has passed it by.

Now were talking.  Affordable, multi-ports and easy to install thanks to Mary from D-Link!  I thought that I had no choice but to go with a Wi-Fi Router for ever which cost me high dollars from Windstream.  I did not want a Wi-Fi router but for years dealt with it even though I used it for Ethernet only.  Many people are waking up to the detriment of Wi-Fi in our airwaves and the effect it has on humans and all living things not to mention demise of the Bees and Butterflies.  It ceases life one by one.  Wi-Fi also has the worst ability to send and receive data not to mention is 100% open to all to tap into for confidential info.  Thank you D-Link for understanding this new alert and offering a true hard wire Ethernet Router.  You made it possible for all of us to continue to use the internet safely.  Mary from D-Link, Agent # AR004217 wins the prize in assisting me with the install of this new little unit.  My case # with D-Link is C66686109 and a very proud customer.  Thank you Amazon and D-Link!

I been using this router now for about a year and I have try several router, but this router is the best by far. I have 33 network connections between wire and wireless and they work perfectly without a drop.

Bought this router yesterday, and compared to my Linksys router which completely failed 1 day after the warrenty expired, I am thus far very impressed.  Linksys slowed down the cable internet big time and made wireless internet nearly impossible, having to reset it every day.  D-Link is by far the better way to go for wireless internet.

I purchased the D-Link DIR-615 (Rev E) to replace/upgrade an older D-Link wireless G router that had been in service for about six years.  This version (Rev E) of the DIR-615 is rock steady with no drop outs.  It works fine in mixed mode connected to both my G devices and N devices.  I see no performance issues when connected to both types of devices at the same time.  Our Wii and Mac Airbook connect via G wireless and the Dell laptop and wireless WiFi Blu-ray player connect via N wireless.  The set up was easy and straight forward.  I did not use the supplied set up CD.  I went into the set up via my browser by entering the address of the router.  For the price, this is a great N router.

This piece of equipment has worked like a charm, great range, strong signal I just wish it was simpler to connect. D-Link systems has a great website to make it simple to connect. I just wish I didn't have to fill all the stuff in but is pretty simple and like I said it's got fantastic range for the price. Works well for me.

Another great product by tp-link.

Very easy to set up.  Very good coverage and it looks sexy.  The wirecutter recommended this and I can see why.  my 5 GHZ speeds are insane.

The UI (user interface) is very simple and easy to figure out.  There is also a great App for TP-Link called "tether".  Great options for parental control without needed a degree in IT.

Almost plug and play.  The speeds I am getting are fantastic.

D-LINK's support is really good.  A representative  (Badge # AR004217) just spent over an hour with me figuring out a connection challenge and updating my settings (Case # C6792740).
  My initial call to D-LINK went through to a live person quickly.  The representative helping me was patient, polite, and considerate.  She helped me through all the steps necessary to diagnose my problem and install the latest firmware.  It took a while, but she hung in there and provided really great service.
  Good hardware is fine, but it eventually needs support.  I'm glad I went with a D-Link product, because the support is outstanding.

I have several and although large they are extremely reliable. I also like the fact that Tp-Link continues to update the firmware regularly.

I purchased this product about 6 months ago. The cisco 4200 router I had wasn't pushing enough signal to get from my computer room/office to the living room where I have a smart TV. The D-Link Range Extender worked great! Set-up was easy (my router has a WPS button on it) and within 15 minutes I was able to stream movies from my PC straight to my smart TV. My kids used the D-link connection to connect their Wii game player. The game room is a good 300 feet away from my computer room/office. They were able to get a connection before I installed the D-link extender but the connection was unstable. Using the D-link connection we were able to use the NetFlix feature of the wii and were never able to do that without the extender.

Sounds great right??

Now for the bad news!

I came home from work yesterday to my wife saying, "the internet was down". She had grown accustomed to using the d-link connection on her iPad to play Candy Crush. If you're addicted to Candy Crush you will understand why this was an emergency. I noticed that my Cisco router wireless signal was still available and my office computer was working fine. The d-link signal was not available. I unplugged the D-link and walked through the setup again (luckily I saved the box and the instructions) only to discover the d-Link was dead.

My D-Link died after 6 flawless months. Has anyone else had this same problem?

BTW: My wife can get her Candy Crush fix again as, she just has to play in a place closer to the Cisco router.
