I laugh every time I see this as a Frontier field tech.
ADSL filters are NOT bi-directional... you have a filter backwards! The filter plugs into the WALL, not the PHONE. Make sure your filter is connected directly to the wall, THEN the phone. ie, jack receptacle, splitter, filter, line cord, phone. To eliminate that whole splitter/filter confusion, I say you should call in and request a field tech come out to install a "NID Splitter." More on that below:
I recommend every ADSL customer, no matter who your phone company is, get a full install.
- There needs to be an ADSL splitter installed at the Demarc outside the house/building, and a homerun (direct line) to the DSL jack to get a decent signal quality.
- Specifically request that your line be groomed. This means conditioning the line to provide the best possible sync rate for your ADSL modem. We would cut bridge tap (google it), eliminate load coils (google it) and provide the shortest loop length with the biggest gauge wire (26awg is baaaad for DSL) possible.
- Also, I highly recommend you call in to ask if you are currently on an Adtran DSLAM, and if not, request to be migrated if one is available. Ill post why below.
- Pro tip: With Frontier, we've been overhauling our ADSL network. We are using Adtran TA5000, and "pole mounted" variants such as the Adtran TA1148a and v to provide newer, faster, and more robust flavors of ADSL2+, as well as adding the capability of Bonded ADSL2+, ADSL2+ Annex-M (Annex-M is tentative, currently its Annex-A), and VDSL2. Currently the highest speed available over our VDSL2 platform is 40/10 in select markets.
For those that are lucky enough to have Fios (fiber to the premise), its a no brainer. Same cost as DSL, but insanely fast internet.
