2 out of 5 eggsNot good by itself- but you can make it work

Pros: -Working good for me as only a wireless access point (so far)
-Shell Shocker price made it worth it

Cons: If this was your sole router for both wired and wireless networking- good luck.

Other Thoughts: I bought this DIR-651 and the DIR-657 router from Newegg each for $20. For $40 total it was worth it- eventually (I almost gave up). First thing- I updated both their firmware. I then spent a lot of time figuring out what worked best because I constantly ran into problems with each, but I was trying to run each as a sole wired / wireless router as they’re intended (my plan was to give one router to a friend). It wasn't until I ran both at the same time- the DIR-657 as my router (for wired only) and using the DIR-651 as an access point (for wireless only) that I had success. I first tried running the DIR-651 as my router, but I found the 657 was better. I then made the 657 my sole router and the 651 as my access point.
I changed the 657 default IP address without a problem so they wouldn’t conflict (I wanted to change the DIR-651’s IP address, but it was so finicky it wouldn’t let me). They both come configured with IP address I changed the 651 to I disabled all wireless on the 657 and made the following changes- I reserved each device I had with Add DHCP Reservation under Setup / Network Settings. Parental Control set to None. WAN Traffic Shaping and QOS Engine Setup disabled. I used all Firewall settings except DMZ. I saved all my settings under Tools / System. Since I’ve done that I haven’t had the 657 drop gigabit networking once. I am copying 4 gig files from one computer to another at average of 112 megabytes per second (smoking fast).
On the 651- I disabled Advanced DNS. I set wireless to 802.11n only. I disabled Auto Channel Scan. Security Mode – WPA Personal – WPA2 Only – AES. I disabled the DHCP Server because I was using it as an access point. I disabled QOS Engine. I enabled all Firewall settings except DMZ. I disabled Dynamic DNS. Saved the Configuration under System.
All these settings worked for me (other settings may work too, but I’m still testing). I actually like having it this way now because I’m a wired guy- I prefer not to use wireless. This makes it easy for me to just unplug the 651 and plug it in when I need it (I have read that high frequency wavelengths may be detrimental to our health- the new routers on the market have taken it a step further and doubled the frequency, but yet nothing is as fast as wired anyway. This also includes high frequency wireless phones. Maybe these frequencies aren’t a problem, but I prefer not to be a guinea pig). This is a review for the 651 and I know I intertwined the 657, but I’m sure you can use a second, separate router as an access point and keep costs down setting it up this way. This also gives you a 6 available LAN ports because you’ll use up one from the router connecting the access point and one from the access point itself- 3 left on each. 6 is better than the original 4. I should also add that I did not test the 651 as a sole wired router. Perhaps these problematic Dlink routers work ok with only using one or the other.

3 out of 5 eggsNeeds a lot of configuration

Pros: Is very cheap. Work great as gigabit switch. Once you do a lot of work with the configuraton it will work very good, even Wi-Fi

Cons: Out of the box, it is junk as Wi-Fi router, Wi-Fi resets all the time, But It can be fixed with setup

Other Thoughts: To fix it you will need:
1 Firmware update to the latest version
2 Configuration: You will find usefull information on D Link forum: topic=39174.0
Also you need to config DNS servers manually
Turn off ALL QoS or Disable Traffic Shaping (DIR only) GameFuel (DGL only and if ON.) options. Advanced/QoS or Gamefuel.
Turn off Advanced DNS Services if you have this option under Setup/Internet/Manual.
Turn on DNS Relay under Setup/Networking.
Setup DHCP reserved IP addresses for all devices ON the router. Setup/Networking. This ensures each devices gets its own IP address when turned on and connected, eliminates IP address conflicts and helps in troubleshooting.
Ensure devices are set to auto obtain an IP address.
Set it to use mixed G and N, NOT b,g and n
Once you get it to work, save your configuration

1 out of 5 eggsDlink DIR-651

Pros: You can use it a as a gigabit switch

Cons: Wireless is unreliable, requires resetting periodically
Cannot change IP address, of the router, or you permanately lose ability to admin the router by IP address. (yes, if have an ip address on the new network, yes I can ping it, no there are no other devices conflicting,yes I rebooted it)
Bottom line: If your OK with the fact that any given time your router "might be working" then this is the router for you.

Other Thoughts: If you cahnge the ip adress of the router you must, configure if by the name dlinkrouter from that point forward. So add an entry to your host file or make sure you point to the router as a dns server.
One star is a generious rating.

2 out of 5 eggsNot an upgrade

Pros: It works, it was cheap, has gigabit ethernet.

Cons: The wifi range leaves a lot to be desired. My old G router I have in my basement has better signal throughout my house than this N router has just two rooms over. Also, even though I have it set for mixed G/N use, I can't get my G laptop to connect, but my tablet works fine switching from one to the other.

Other Thoughts: I have the DIR-651 set up as a second wifi access point connected to my home network through gigabit ethernet. It does what I need it to do but was hoping for better. Even though it says it's capable of 300mbps, I could only get it to connect at 130mbps to any device. Better than G speeds but not even close to spec, and that's in the same room. Signal coverage is horrible despite two antennas. Would return it but not worth the return costs, only paid $20 for it.

3 out of 5 eggsD-Link DIR-651 Review

Pros: Wireless N, Gigabit Networking allows for faster network transfer speed of files/folders over 500MB. Smaller and uses less electricity compared to my older WRT54G. Standard complement of settings to be expected from an N generation router.

Cons: Setup for gamers/hobbyists/professional users can be a hassle since the manual provides little in the way of detail or even good definition of features. You will turn to the manual for help when the router, even with the latest firmware the router will still have problems.

Other Thoughts: Many people report having all sorts of internet slow downs, connectivity issues, etc.
I keep a secure network (no SSID broadcast, wpa2 + tkip, etc etc. With few new devices being connected to my router, I was able to create a DHCP reservation list under the manual setup/network settings page "inside" the router. This seems to have corrected the apparent issues I encountered with slow web-browsing on devices on the reserved list.

2 out of 5 eggswas not an upgrade

Pros: it worked, could easily set admin password, SSID, encryption

Cons: advertised application for large home, supposedly faster and with wider coverage, did not perform as well as 5 year old Linksys G router/access point

Other Thoughts: went back to store

5 out of 5 eggsGreat, Cheap, Tiny, Gigabit router after firmware update

Pros: I have had no problems with video Skype, torrents, or gaming. This router paired with my unrestricted 200Mbs fiber connection from my ISP equals super smooth and fast connections. I can now transfer 20GBs files in minutes over my wired network and the wireless coverage is so wide and fast. I can't believe I got all this for less then $60 and in such a small package.

Cons: Open WRT and DD-WRT don't work yet. There are a lot of settings and option in the setup menu and it can be a bit confusing because D-Link uses different terms and words for functions that all the other companies seem to use common tech terms for.

Other Thoughts: My DIR-651 came installed with 1.00 but after reading many reviews and forums about the problems the router had and the fact that firmware 1.10 fix the problems I installed it and it is great. People having internet problems after the 1.10 firmware update might be restricted by ISP limitations.

1 out of 5 eggsGarbage

Pros: None to speak of - would say low price - but the quality is lower so that is not a pro

Cons: Everything - drops connections - lack of features. I am in a deployed environment, so internet connectivity is already slow - doesnt help when the router sucks.

Other Thoughts: all around worst router I have owned...

4 out of 5 eggsits ok

Pros: This router is OK. I was looking for a cheap gigabit solution and this is what the local store had. I was in back and forth between this one and a buffalo ($15 bucks more) but this one does its job

Cons: Without the firmware, you will get all the problems from previous users. It was recently updated and the updates do their work..otherwise prepare for disconnection issues as well as not saving the settings after a reboot. No DDWRT support.

1 out of 5 eggsThe reviews are correct.

Pros: Small, simple design. Gigabit LAN. No overly-bright obnoxious looking lights like with other routers. Price.

Cons: 1. Devices connected via wi-fi will lose connection and subsequently, are unable to reconnect automatically because the router has a problem issuing IP addresses. Rebooting the router fixes the problem temporarily but it has to be done at least daily...sometimes multiple times per day. The only way I've found to resolve the problem is to issue static IP addresses to each device but that's impractical for me.

2. Wi-Fi range is mediocre.

3. Browser setup interface is "clunky", awkward and anytime a setting is changed, the router takes 60-75 seconds to save the setting before you're able to continue making any other changes.

Other Thoughts: I've owned and setup several different wireless routers from various manufacturers (including D-Link) over the past 15-20 years. This router is by far, the worse I've experienced.

I could have dealt with the mediocre wi-fi range and the awkward user interface and been satisfied with the router but the wi-fi connection issues were downright frustrating.

With previous wireless routers, I was accustomed to just picking up whatever device I wanted to use (smartphone, laptop, tablet, etc.) and being able to connect to the internet instantaneously. That convenience came to a screeching halt with the DIR-651.

I figured that since it had comparatively few reviews, the bad reviews must have been due to user error. Not so! This is just a bad router and updating the firmware to the latest version didn't help at all.

I've never before felt compelled to post a negative review about a product but the DIR-651 makes it easy.
