5 out of 5 eggsAn excellent ADSL2 Modem/CPE/Router

Pros: I'm not absolutely sure why this modem CPE has such horrid comments. It ain't a Cisco although it's the best modem I've ever owned. TP-Link is excellent for the price and can't be beat. This thing is very responsive and works nicely w/ my Centurylink ADSL2 in bridge mode and in router mode. Very stable, very low latency, exactly as described.

Cons: It is plastic

Other Thoughts: It needs to be metal

1 out of 5 eggscould never get it working my dsl

Pros: price was nice

Cons: i could never get it to work with centurylink they have a ppoe password login network. no matter how many times i type it in i couldn't get it going,even got on the phones with their techs.

Manufacturer Response:

Dear customer,
We apologize for the inconvenience caused.
may I provide you some suggestions?
1. Check if your line is ADSL or VDLS; The TD-8840T is an ADSL modem router. If your service is VDSL, the TD-8840T cannot work on it;
2. Check with Centurylink the following parameters and then reconfigure the modem router again:
VPI/VCI
WAN Connection Type
Encryption

If you need further info, please don't hesitate to drop me an email@ howard.he@tp-link.com
Best Regards!

3 out of 5 eggsVulnerable

Pros: (trying to be nice) Configuration offers plenty of options
Inexpensive
Nice features: 4 ports and QoS

Cons: US-CERT Vulnerability 834723: "The TP-Link 8840T DSL router's remote management feature is enabled by default." -- that is, a remote attacker can log on with the default password. I actually think the router is a bit adaptive, but this is still really weak. ie: SPI is disabled by default in their latest firmware.

I'm getting lots of unexplained errors in the log. Thousands.

Other Thoughts: The connection is stable, but two things together are enough for me to look for another product.

I don't know what to make of tp-link. (is "TP" for Twisted Pair, or Toilet Paper?) They have products with a lot of features and (apparent) value for money, but they suffer from significant flaws. If they work hard to improve quality, then they have a lot of potential.
