TP-Link TL-WDN4800 - 5GHz Not Found Solved! (Hackintosh & Windows)

TP-Link Wireless Card




Recently I have been having issues picking up the 5GHz channel from my router using the TP-Link TL-WDN4800. Some days I would boot up and the computer picks it up from the jump but in the past few days, it would give me network errors dropping downloads and the Internet connection itself. At first, I thought it was my ISP but my Samsung S7 Edge and Apple iPad Mini 4 all seemed to be finding the 5GHz channel with ease. I did some Google-fu and found it has to deal with how the NIC picks up 2GHz/5GHz channels sent out from your router. I believe my ISP router was switching to higher channels on the 5GHz channel automatically and causing network errors when I was downloading huge files over WiFi from either compensating with the huge network downloads (2GB and up) or from the surrounding competing neighboring routers on my street.


I changed out from the boxy router that was provided by my ISP and switched it out with a Netgear Nighthawk R6700 (AC1750). Even with the switch, the TL-WDN4800 only recognized the 2GHz channel. Then, I found information on the hackintosh forums that the TL-WDN4800 would only recognize or find the 5GHz channel on certain defined channels. The Netgear R6700 had 153 set as the 5GHz channel up to 1300Mbps speeds. Switching it to channel 48 all of a sudden the WiFi card found it with ease. Subsequent tests confirmed my findings when I downloaded roughly 3GB of data without any errors or connection drops. Supported channels for 5GHz connections are as follows: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 36, 40, 44, 48, 52, 56, 60, 64.


Under El Capitan, channel 44 was recommended as under OS X Yosemite channels were different.

Historic Killingly Ballouville Mill

Image
  As I recall that April day in 2018, the memory unfolds with the vividness of a carefully preserved photograph. The sky, a vast expanse of unyielding blue, served as the perfect backdrop for our excursion. J and I, driven by curiosity and a keen sense of adventure, stood at the threshold of the historic Ballouville Mill in Killingly, Connecticut. This relic of a bygone industrial era was nestled imposingly between two homes as if guarding the secrets of its storied past. Our entry into the mill was less an act of intrusion and more a gentle push through time's veil. An opening – not quite a door, nor a window – beckoned us into the heart of a forgotten world. Inside, the mill presented itself as a cathedral of industry, now silent and solemn. Wooden beams and columns, like the ribs of a great leviathan, stretched upwards, supporting the weight of history and time. The machinery, once the pulsing heart of this place, had long since ceased their hum of productivity. In their absence

Doorway on the Passaic River

Image
In the realm of industrial history along the Passaic River in Northern New Jersey lies a captivating tale of an oil company's struggle for survival against the evolving landscape of progress. Amidst the modernization of Route 21 in the 1950s, the Riverbank Petroleum Company later renamed to Northern New Jersey Oil Company stood as a fierce opponent to the development. Their existence pivoted on the river's access, a lifeline for their business. Relinquishing it meant demise, so they fiercely contested the eminent domain battles. Ultimately, a compromise was reached: a tunnel beneath McCarter Highway, enabling oil transportation without disrupting the flow of the newly expanded route. Riverbank Petroleum Company Wharf had its last recorded shipment of under 2,000 tons of fuel oils in 1997. Time has seen the oil company fade into history, leaving behind an abandoned, flooded tunnel. However, a peculiar sight remains – a doorway, a relic from the past, etched onto the side of Rou

Rockaway Metal Products Corporation

Image
Rockaway Metals Products (RMP) began as a sheet metal fabrication factory beginning in 1961. RMP occupied the site from 1971 to 1987 leaving a plethora of hazardous waste materials onsite. From 1990 to 2004 the building housed various tenants which even included an auto repair shop. Rockaway Metals a manufacturer of filing cabinets and other metal products closed down in 1987. It was leased a few years ago to different owners who did not manage the 4.85-acre parcel. The 155,000-square-foot building has long been an eyesore and trouble in the neighborhood since its closure. A coastal storm in March 2018 blew debris materials to adjacent properties. Rockaway Metals was acquired by Nassau County in 1995 by tax deed. The county has held onto the property for 22-plus years. In February 2011, the site was damaged by fire and condemned soon thereafter. For more in-depth legal ownership of the property, you can read more below in the source list under U.S. v. 175 INWOOD ASSOCIATES LLP.

Abandoned Factory Z (Northeastern, USA)

Image
Update : A full research write-up of International Silver Company's former Factory H boiler house .  This abandoned northeastern factory sits in the back of a quiet residential street surrounded by nature. Next to this two-story building remains another abandoned medical complex boarded up to the gills. Stay tuned for upcoming flicks. Getting into this building was quite hard. We hopped a perimeter fence in the middle of the morning just before a police car was sitting taking a quiet break or making their due diligence check on the property. This property is down the road at a current asbestos abatement medical hospital by the local town/state agency. Once on the property, it offers a mix of old machinery and pipework from this little factory which was probably much larger before residential developers took over. In addition, the building was free of graffiti and its brick-walled facade still looked like the day it was constructed. The only giveaway is the wide-open away roof

Former 75th Police Precinct Station House Renovated

Image
From Policemen to Priests: A Timeline of the Precinct-Turned Church   In the heart of the Cypress Hills neighborhood of Brooklyn, a piece of the city's history stands resilient against the march of time. The corner of Liberty and Miller Avenue hosts the formidable visage of what was once the 75th Police Precinct Station House. With its 19th-century bones and layered past, this station is a chronicle of the urban evolution, from its humble beginnings as the 17th Police Precinct—boasting a modest band of 38 men—to a bustling precinct accommodating 60 patrolmen, 14 horses, and a curious duo of police cats. This remarkable transition was ushered in by Captain Hugh Frank Gorman and his team on a balmy summer day, June 2, 1982. In its heyday, this precinct governed the largest territory in New York City, a sprawling nine-square-mile jurisdiction stretching from the fringes of Queens County to the town of Flatbush, and from the waters of Jamaica Bay to the county line. Within this labyrin
