The increase continues to be driven by higher depreciation and amortization of our fiber network assets, up 60% year-over-year. Total operating expenses for the fourth quarter of 2022 increased 16% to $30 million from $26 million for the same period last year. The increase is primarily the result of the following: People costs were up $2.7 million this quarter with increased workforce costs to support business expansion related to Ting Internet growth, as well the continued Wavelo ramp. Sales and Marketing costs increased by $0.4 million year-over-year, mainly driven by increased investments in the Ting Internet business expansion. Facility and third-party contracting and support costs were up $0.9 million, and credit card fees were up $0.3 million, while stock-based compensation increased at $1.9 million year-over-year.
These were offset by a reduction in professional fees of $1.1 million and lower bad debt charges of $0.4 million. And lastly, foreign exchange impacts decreased expenses by $0.2 million this quarter, primarily driven by the year-over-year impacts from the revaluation of our of foreign-denominated monetary assets and liabilities. As a percentage of revenue, operating expenses increased to 38% for Q4 of this year from 31% for the same period last year. We reported a net loss for the fourth quarter of 2022 of $13.4 million, or $1.25 per share, compared with net loss of $2.0 million, or $0.18 per share, for the same period of last year. The net loss was driven predominantly by higher interest expenses, including the new preferred debt with Generate Capital; the accelerated build of our fiber network and ongoing ramp of the Ting Internet operations and related higher operational and depreciation expenses; and higher stock-based compensation and investment into the Wavelo platform.
Note, our tax expense reflects our geographic mix, with taxes payable in Canada on our legacy domains business. Adjusted EBITDA for Q4 was $6.7 million, down 47% from $12.7 million for Q4 2021. That total breaks down amongst our three businesses as follows: Adjusted EBITDA for Tucows Domains was $10.6 million, down 3.7% from Q4 of last year, reflecting the normalization of renewals to pre-COVID levels. Adjusted EBITDA for Wavelo was negative $1.1 million, a decrease of 119% from a positive $5.9 million last year. The decrease is primarily due to lower high-margin professional services from DISH, an impact of $2.9 million, and a contract asset-related revenue recognition impact related to the reassessment of fixed payments in the DISH agreement.
The contract asset and associated revenue recognition varies based on the estimated relative mix of variable and fixed payments. The year-over-year impact of the contract asset change was negative $2.1 million this quarter. As of December 31, 2022, the contract asset balance is $7.5 million, and it will unwind as a contra revenue over the term of the contract, which is up for renewal in Q3 2024. Adjusted EBITDA for Ting was negative $6 million compared with negative $4.8 million in Q4 2021 as we continue to invest in our fiber network expansion. And finally, the Corporate category had adjusted EBITDA of $3.3 million this quarter as compared to $0.6 million in Q4 last year with the increase primarily driven by lower corporate expenses this year versus last year, including one-time items in Q4 2021 and a higher earnout from the sale of the Ting Mobile customers to DISH.
Turning to our balance sheet, cash and cash equivalents at the end of Q4 were $23.5 million, compared with $30.5 million at the end of the third quarter of 2022 and $9.1 million at the end of the fourth quarter of 2021. During the quarter, we had $2.9 million in cash from operations compared with $10.5 million in Q4 last year with the decrease being due to our lower net income once adjusted for non-cash items. The working capital impact was consistent year-over-year. Our cash was more than offset by our investment of $36.7 million in property and equipment, primarily for the accelerated build-out of the Ting Fiber Internet network, in addition to the continued investment in the Wavelo platform. Note; that number reflects the actual cash paid for capital assets in the quarter on our cash flow statement.
