1.0 out of 5 stars Disconnects all computers every few hours., November 1, 2007
Verified Purchase(What's this?)
This review is from: NETGEAR GS108NA ProSafe 8-Port Gigabit Ethernet Desktop Switch (Personal Computers)
Very disappointed. I have other Netgear components on the network that have worked flawlessly for years, but this particular model does indeed have the issue many people have reported about disconnects. I could see how an average email checking / web surfing user would not care much about it, but I use software for work that requires a full restart when disconnected, so this switch drives me absolutely crazy.

Every few hours everything attached to it just disconnects, as if they are plugged into nothing. Sometimes it comes back up in about 2 minutes, about 25% of the time I need to unplug the unit and plug it back in to get it to reconnect to the computers again. I am back on Amazon to find a different switch and figured I'd warn everyone that this one is headed for the trash bin here. I still believe Netgear makes a great product, just this particular unit is flawed. Funny sidenote, actually disconnected me two times while writing this, don't think it wanted me to warn everyone about it. :-)

Why would you throw this in trash bin? I thought that the Netear PRO had a lifetime warranty. Why not send it back toNetgear for a new one, unless you don't think you can get a good one.

Another reviewer has also commented. Netgear won't honor their obligations, and if they do replace it. It will be another defective unit. I am trying a new HP that has not arrived yet.

I have the same problem with a GS108 and a GS116. The half-life seems to be about 6 months of power-on time. The switch itself then fails with constant link resets until it's allowed to "cool off" for an hour or so. Then, it only takes 20-30 mins to "warm up" and re-fail. Replacing the power supply doesn't help. It's not an attached device issue (different sites, different equip, same failures.

Truly, it seems like most of the sub-$500 switches have high failure rates, but the ones with case fans seem to have fewer complaints. At the cost, it's sometimes worth the peace of mind to toss it in the trash.

Retail models DO have lifetime warranty. It does take some patience and perseverance to get approval for RMA. Cross ship is $20, so keeping a spare, or paying for cross-ship is important. Alternatively, an RMA replacement could be sold to someone else and the $$ put towards a new JGS series switch.

The exact cause of this problem is the wrong capacitors they used in these switches. I personally went to radio shack and picked up four 1000 uF electrolytic capacitors (part number 272-1032) of which are rated at 35 volts instead of the 6.5 or so volts that they used. These are bigger than the originals since higher voltage rating, so I had to solder them in straight legged up and then bend the legs at a 90 degree angle to get the board to fit back into its casing. So, whenever you replace a capacitor either match or exceed the voltage rating, but do not use a different capacitance value (1000 uF in this case).

I grabbed four since two of these go into each switch. I have this model (GS108) and the five port version (GS105). So far I haven't had to replace the capacitors in the GS105, but you never know it might fail too. Ever since I replaced the capacitors in the GS108 switch it has worked perfectly fine as if it were brand new and still working after two years of replacing the capacitors.

Good to know. Thanks for the info, since I still have a GS105 I keep for spare.

Same thing happened to a video card, evidenced by popped caps. I found out that there's a whole slew of people who bought the cards and upgraded the capacitors for increased stability.

With the low cost of discreet semiconductors in bulk, I just don't see why they would think that saving literally 5 cents per unit would be worth the increased failure rates and corresponding customer dissatisfaction.

If the wall-wart power supply is 5V, then 10WVDC or even 6.5WVDC capacitors should work fine forever, as long as the parts' Working Voltage rating is at or above the maximum supply voltage OVER THE ENTIRE TEMPERATURE RANGE. If the OEM capacitors are failing, it may be due to low quality, and simply getting known-good parts of the same rating should solve the problem. I'd also check the wall-wart power supply: If it produces an unloaded output greater than 5.25V, it should be replaced with a well-regulated unit that maintains 5V +/-5% (4.75V-5.25V). No offense, but much of what RadioShack sells is classed as "hobby grade"; one would be better off ordering the parts from an industrial distributor, such as Digi-Key, Mouser, etc.

I found that Trendnet were cheap and reliable. When I ditched my NetGear, I got the TRENDnet 8-Port Unmanaged Gigabit GREENnet Standard Switch (8 x 10/100/1000Mbps). It's been running solid for 2 years now, as has a 5-port I'm using elsewhere. These are pretty close to the size of the netgear, half the cost, and the status LEDs are on the front, with all wires going out the back.

While the NetGear has lifetime warranty, that's quickly negated by shipping costs at the second replacement. The TrendNet has a 5-year warranty which is pretty decent.

Wow. I never knew switch-buying could be so complicated. I bought a rosewill 8 port 10/100 switch 5 years ago for $12.99 and never had a problem. Still rock solid but I wanted to upgrade to gigabit and thought I would shop around. Thanks for the warning on this.

In reply to an earlier post on Mar 31, 2012 3:21:24 PM PDT
Yah, gigabit is more sensitive to timing issues, which means the heat must be kept lower. That's where almost all of these issues come from. You find that the rated temperatures are different, except the cheaper switches overheat inside, even in "good" conditions.

My TP Link switch is going strong after 2 years. Almost the same as the netgear, but just a little better, and a lot more reliable. Also, uses less power.

What model switch is your TP Link? Is TP Link a good make overall?
